HUAZHENG - Model HZYDP-30KV - High Voltage VLF Hi Pot Tester

Power supply: 220V±10%, 50±5%Hz

Note: When a portable generator is used for supplying power, it is required that output voltage and frequency of the generator shall be stable (generally it is required that power shall be greater than 3 kW, the frequency shall be 50 Hz, and voltage shall be 220V±5%), otherwise some assistance measures shall be used to stabilize output of the generator.

Output voltage precision:

Degree of instability for peak value of output high voltage: ≤1%

Degree of instability for frequency of output voltage: ≤3%

Distortion rate of output voltage waveform: <5%

The instrument has the function of not burning the booster and the mainframe in case of power failure and sudden shutdown during the operation.

Service environment: Temperature: -10⁰C~+40⁰C, humidity: ≤85%RH

Description of testing range:

1. The capacitance of the tested product shall not exceed the maximum rated capacitance of the instrument, and the value is as shown in Table 1;
2. If the capacitance of the tested product is too low, the waveform would be affected. If it is lower than 0.05µF, the instrument would not output normally, so that the auxiliary device (optional) provided by the company can be adopted.
3. For capacitance estimation of common electrical equipment, see Table 2 and Table Table 2 Single-phase to Ground Capacitance of Different Types of Generators
