State Grid JP Cabinet Low Voltage Standardized Special 20KV Impulse Voltage Tester

State Grid JP Cabinet Low Voltage Standardized Special 20KV Impulse Voltage TesterIt is a voltage wave test device with a waveform of 1.2/50Is. The front time of the instrument is 1.2I, and the back time is 50I. The instrument meets the requirements GB／T 14048、GB／T10963、GB／T16916、GB／T 16917、GB／T 14711、IEC255-5 Standard, used to test the ability of components to withstand transient overvoltage, as well as the electrical clearance and creepage distance of appliances.

Precautions

★State Grid JP Cabinet Low Voltage Standardized Special 20KV Impulse Voltage TesterAs a high-voltage tester, it has high voltage, high energy, and high danger if touched, which endangers human safety. The power supply of the instrument must be reliably grounded, and this manual must be carefully read before use. Be extremely careful when using, and always pay attention to personal safety. When the interval time relay, impact frequency relay are on, and the DC voltmeter is reading, do not touch the 1H and 2H high voltage output terminals, output lead clips, and test samples to avoid electric shock.

To ensure the reliable operation of the instrument, the power supply of the instrument also needs to be reliably grounded. It is strictly prohibited to conduct high-voltage impact tests without a grounding wire. Because thousands of volts of voltage can damage low-voltage control and detection units.

Before polarity conversion, the high voltage should be continuously pressed firstStop pressingButton until the high voltage metercharging voltageOnly when the display is close to zero can it be carried out, otherwise, the high voltage that reverses instantly will cause damage to the instrument.

When it is necessary to detect the waveform and peak voltage of the instrument, it can be done throughWaveform detectionVoltage divider detection (voltage divider ratio of 50:1).

When the instrument malfunctions and needs maintenance, it should be carried out by professional personnel. When opening the box for maintenance, the high-voltage capacitor should be discharged with a grounding wire before proceeding to avoid electric shock.
