3. Persiapan Sebelum Ujian

3.1 Urutan Pengkabelan Perangkat Keras

Connect ground terminal ① on the back of the host to ground, as shown in Figure 3-1.

Gambar-3 1

The two ports labeled ① and ② on the front of the main unit are both built-in CDN output ports that can be connected to the EUT (Equipment Under Test). Select one based on the EUT’s current and wiring configuration; see Figure 3-2.

Gambar-3 2

For safety reasons, the EUT may be placed in the sample box, as shown in Figure 3-3.

Gambar-3 3

Note 1: Before testing, verify that the EUT is in normal operating condition and meets the product’s rated operating conditions.

Note 2: The EUT should preferably be placed on the left side of the equipment so that the EUT connection cables do not need to pass in front of the surge generator’s touchscreen, thereby preventing interference with the touchscreen during the test.

For the Isolation Transformer wiring, see Figures 3-4 and 3-5. Depending on the EUT’s rated current and wiring configuration, connect one of the output ports (① or ②) to the built-in CDN input port (④) on the back of the host unit. Port ③ is the input port; connect the Isolation Transformer’s power cord to it.

Gambar-3 4

Gambar-3 5

Next, connect the power cords of the Surge Generator and the Isolation Transformer to an appropriate power source.

Note: The Isolation Transformer is used only to supply power to the EUT via the host’s built-in CDN; the Surge Generator’s own power supply does not need to be connected to the Isolation Transformer.

3.2 Konfirmasi Parameter Uji

3.2.1 Pemilihan Tingkat Tes

Based on the EUT installation environment and product standards, select the corresponding test level (priority levels are listed in the table below); lower levels must meet compatibility requirements:

5. Pengujian Lonjakan

5.1 Prosedur Operasional

After all the parameters in the touchscreen program have been set, turn on the Isolation Transformer. Turn on the air circuit breaker for the built-in network CDN on the back of the main unit, as shown in Figure 5-1.

Gambar-5 1

Start the test; see Figure 5-2.

Tangga	Note
①	Click “EUT Power” to power on the EUT
②	Then click “Start” to begin the test.

Gambar-5 2

If the oscilloscope function is checked, the program interface will display the surge voltage and current waveforms after each surge output, as shown in Figure 5-3:

Gambar-5 3

Note: When the EUT is connected and testing is proceeding normally, the surge voltage and current values and waveforms will be affected. The surge voltage and voltage waveform (1.2/50 μs) specified in the standard must be measured under a fully open-circuit condition; the surge current and current waveform (8/20 μs) specified in the standard must be measured under a fully short-circuit condition.

Open circuit, meaning that no EUT or cable is connected to the CDN output terminal, as shown in Figure 5-4:

Gambar-5 4

For a complete short circuit, the two ends of the surge coupling direction must be short-circuited. For example, if the current coupling direction is set to L> N, the L and N terminals at the CDN output must be short-circuited, as shown in Figure 5-5;

Gambar-5 5

5.2 Menentukan Apakah EUT Telah Lulus Uji

Tingkat	Kriteria evaluasi	Lulus atau Gagal	Gejala Khas
Nilai A (Kriteria A)	Performa sepenuhnya normal dalam batas yang ditentukan, tanpa anomali apa pun.	Biasanya dianggap telah lulus	No downtime, resets, display errors, or data loss; key parameters are within acceptable limits.
Nilai B (Kriteria B)	Temporary loss or reduction in function or performance, but recovery occurs automatically once the disturbance ceases, without the need for operator intervention	Harus diatur terlebih dahulu; umumnya dapat diterima.	Secara otomatis melanjutkan pemutaran setelah gangguan komunikasi singkat; kembali normal setelah layar berkedip; kembali normal setelah penyimpangan singkat dari parameter.
Kelas C (Kriteria C)	Temporary loss or reduction in functionality or performance that requires manual intervention to restore (e.g., restart, reset)	Harus diatur terlebih dahulu; dapat diterima dalam situasi tertentu.	Jika peralatan macet, peralatan tersebut harus dihidupkan ulang secara manual; jika program mengalami kerusakan, program tersebut harus dimuat ulang; jika parameter berada di luar rentang yang ditentukan, parameter tersebut harus disesuaikan secara manual.
Nilai D (Kriteria D)	Hilangnya fungsi secara permanen atau penurunan kinerja akibat kerusakan perangkat keras/perangkat lunak atau kehilangan data.	Ditetapkan sebagai kegagalan	Komponen terbakar, papan sirkuit rusak, data yang tersimpan hilang secara permanen, fungsi inti tidak dapat dipulihkan.

5.3 Post-Test Procedures

5.3.1 Pemutusan Peralatan

Jika EUT terlihat rusak selama pengujian, segera ketuk “Hentikan Pengujian” pada layar sentuh dan ketuk “Daya EUT” untuk mematikan daya EUT.

If no abnormalities occur during the test, wait for the surge test to end automatically, then click “EUT Power” to turn off the EUT’s power.

Turn off the circuit breaker for the host’s built-in network CDN.

Wait 5 minutes to ensure that the high-voltage capacitors inside the main unit have fully discharged, then replace the EUT for testing, or turn off the power to the main unit and the Isolation Transformer.

5.3.2 Tidying Up and Cleaning

Bersihkan area pengujian dan lap dengan kain kering. Jangan gunakan alkohol atau bahan pembersih korosif.

Surge testing is a destructive test; it does not automatically generate a test report, but the device automatically saves the test data. You can go to “System Information,” click “Test Log,” and export the corresponding test data to a USB flash drive via the USB port. The exported file is in TXT text format, as shown in Figures 5-6.

Gambar 5–6

6. Perawatan dan Pemeliharaan Rutin

6.1 Penyimpanan Peralatan

6.1.1 Persyaratan Penyimpanan Jangka Pendek

Jika peralatan tersebut digunakan setiap hari, tidak diperlukan tindakan lebih lanjut setelah setiap pengujian selesai dan peralatan telah dibersihkan.

6.1.2 Persyaratan Penyimpanan Jangka Panjang

Jika perangkat tidak akan digunakan dalam jangka waktu lama (lebih dari satu bulan), harap lepaskan semua kabel dan tutupi perangkat dengan penutup debu untuk mencegah penumpukan debu.

The device should be powered on once a month and left on for half an hour to prevent the aging of electrical components (such as capacitors and contactors).

6.2 Persyaratan Interval Kalibrasi

To ensure the instrument’s measurement accuracy and operational reliability, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. Users may determine the specific calibration interval based on frequency of use, environmental conditions, and quality system requirements.

7. Gunakan perangkat eksternal untuk memverifikasi keluaran lonjakan arus.

7.1 Using an External Oscilloscope (Using the LISUN Osiloskop Seri OSP sebagai Contoh)

7.1.1 Menggunakan Port CRO

7.1.1.1 Melihat Bentuk Gelombang Tegangan Lonjakan

Set the following parameters for the Surge Generator: Set the surge voltage to +1 kV, set the coupling direction to L to N, set the interval as short as possible (e.g., 5 seconds), and set the number of surges to a higher value to make it easier to view each waveform.

Do not connect any EUT; ensure that the circuit is completely open. Then, use the coaxial cable provided to connect the lightning surge tester’s ① “CRO-V” port to the ② oscilloscope, as shown in Figure 7-1.

Gambar-7 1

Press the ① “Menu” button below the ② “Trigger” button, as shown in Figure 7-2.

Gambar-7 2

See Figure 7-3: ① Select the connected channel; ② Set the trigger mode to “Normal”; ③ Click to proceed to the next page.

Gambar-7 3

See Figure 7-4; ① Select the rising edge.

Gambar-7 4

As shown in Figure 7-5, press the ① CH1 knob.

Gambar-7 5

See Figure 7-6: ① Select the 1X range; ② Turn off the current test function.

Gambar-7 6

The SG61000-5 series surge generator has a built-in 1000:1 Voltage Probe at the CRO interface. If the surge voltage is set to +1 kV, the actual voltage applied to the oscilloscope is 1 V. Refer to Figure 7-7. Turn the ① CH1 knob to set the ② oscilloscope’s vertical scale to 1/5 per division, or 200 mV, which makes it easier to view the entire waveform. Turn the ③ “Scale” knob to set the ④ oscilloscope’s horizontal time scale to 10 µs per division.

Gambar-7 7

Refer to Figures 7–8. Turn knobs ① (left/right) and ② (up/down) to adjust the waveform display to the appropriate position shown in the figure. Turn knob ③ (“Trigger”) to adjust the level to approximately the middle position.

Gambar 7–8

For the lightning surge test on the touchscreen, do not click “EUT Power”; instead, click “Start” directly. As shown in Figures 7–9, each time a surge is output, the oscilloscope will capture a surge voltage waveform as illustrated below. Use the horizontal cursor to verify the surge output voltage. Since the Surge Generator is set to 1 kV, the oscilloscope should display a reading of 1 V.

Gambar 7–9

Use the vertical cursor to confirm the surge half-width time; see Figure 7-10.

Gambar 7–10

Set the time base to 1 µs, leaving all other settings unchanged. Wait for the next surge output, then use the vertical cursor to determine the rise time of the surge, as shown in Figure 7-11.

Gambar-7 11

7.1.1.2 Melihat Bentuk Gelombang Arus Lonjakan

Keep the Surge Generator settings unchanged. ① Connect the coaxial cable to the “CRO-I” port to prepare for monitoring the surge current waveform. ② Short-circuit L and N to ensure a complete short-circuit condition. See Figure 7-12.

Gambar-7 12

The impedance between L and N in differential mode is 2 Ω, so the vertical scale of the oscilloscope is set to 1/2/5 = 100 mV. The horizontal scale is set to 5 μs. The other settings are the same as when viewing voltage waveforms. The same procedure is used to measure the output surge. The oscilloscope displays the waveform shown in Figure 7-13.

Note: Here, the current is determined using the method for measuring voltage. The actual current is 1000 V / 1000 / 2 Ω = 500 mA, which corresponds to the 500 mV shown in the figure below.

Gambar-7 13

To view the half-width, see Figure 7-14.

Gambar-7 14

See Figure 7-15 for the leading edge time.

Gambar-7 15

7.1.2 Menggunakan Port Output CDN

The built-in digital oscilloscope and CRO port are both provided to make it easier for users to view waveforms. However, if you need to calibrate the device, you must provide your own high-voltage probe and connect the oscilloscope directly to the CDN output port on the front panel of the surge generator. Refer to Section 7.1.1 and the scale of the high-voltage probe you are using when operating the oscilloscope.

7.2 Menggunakan Tabung Pembuangan

Tabung pelepasan dapat digunakan untuk memverifikasi dengan mudah apakah suatu perangkat menghasilkan lonjakan tegangan.

Connect the discharge tube to the Surge Generator as the EUT. For the Surge Generator’s program interface settings and discharge tube connection, refer to Figure 7-16:

Gambar-7 16

Do not click to turn on “EUT Power”; instead, click “Start” directly to begin the surge test. See Figure 7-17:

Gambar-7 17

When the surge is output, the discharge tube will flash; please dim the lights in the room to make it easier to observe. See Figure 7-18:

Gambar-7 18

This indicates that the device is indeed producing an output surge. If the discharge tube does not flash, please contact customer service.

8. Pemecahan Masalah dan Penyelesaian Masalah Umum

8.1 Perangkat tidak mau menyala

Gejala: Setelah menyalakan sakelar daya, perangkat tidak merespons (lampu indikator tidak menyala, dan kipas tidak berputar).

Kemungkinan penyebabnya: ① ​​Kabel daya tidak terhubung dengan benar atau rusak; ② Tegangan suplai tidak normal; ③ Sekring putus; ④ Varistor (MOV) terbakar.

Troubleshooting: Ensure the power cord is intact and securely connected. Power supply issues—such as unstable voltage, excessively high voltage, or harmonic interference—can cause the fuse or varistor to blow. It is recommended to use a voltage-stabilized, clean sine-wave AC power supply to power the device. Replace the fuse or varistor with one of the same type.

For the fuse locations, see Figure 8-1:

Gambar-8 1

See Figure 8-2 for the location of the MOV (metal-oxide varistor) inside the filtered power supply:

Gambar-8 2

8.2 Circuit Breaker Trip in the Laboratory

Symptom: When a surge is output, the laboratory ground-fault circuit interrupter trips.

Kemungkinan penyebab: Transformator isolasi tidak terhubung.

Prosedur: Hubungkan Transformator Isolasi seperti yang dijelaskan pada Bagian 3.1. Pengujian lonjakan arus menghasilkan arus pulsa sesaat yang besar; jika Transformator Isolasi tidak dihubungkan, hal itu dapat menyebabkan pemutus sirkuit gangguan tanah laboratorium (ground-fault circuit interrupter) mati.

8.3 Restart Perangkat Otomatis

Gejala: Perangkat akan otomatis memulai ulang saat terjadi lonjakan daya.

Kemungkinan penyebab: Kabel ground tidak terhubung dengan benar.

Solusi: Lihat Bagian 3.1. Hubungkan terminal pentanahan PGND di bagian belakang host ke ground, dan pastikan resistansi pentanahan ≤4Ω; jika tidak, tegangan tinggi mungkin tidak dapat dibuang dengan aman, menyebabkan perangkat secara otomatis memulai ulang.

8.4 Uji Sudut Fase Lonjakan Gagal

Symptom: The synchronization phase angle was set, but the surge test was not performed according to the corresponding phase angle.

Possible cause: The EUT power is not turned on.

Prosedur: EUT (Equipment Under Test) harus diberi daya oleh sumber AC, dan harus dinyalakan selama pengujian agar generator lonjakan daya dapat mendeteksi bentuk gelombang daya EUT dan melakukan uji lonjakan daya sesuai dengan sudut fasa yang telah ditetapkan.

8.5 Bentuk gelombang mengandung interferensi.

Symptom: When using the built-in digital oscilloscope or the CRO port to examine a standard surge waveform, zooming in on the waveform reveals some noise. See Figures 8-3 and 8-4:

Gambar-8 3

Gambar-8 4

Possible cause: The built-in digital oscilloscope and CRO port are intended to make it convenient for users to quickly and easily obtain waveform data, but they may generate a small amount of noise.

Procedure: If you need to obtain the actual output waveform of the surge generator, or if you wish to calibrate the device, use an oscilloscope and a high-voltage probe to directly inspect the waveform at the CDN output terminal, as shown in Figures 8-5 and 8-6:

Gambar-8 5

Gambar-8 6
