Feature

1.Very Low Frequency AC Hipot Test :

1). Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.     

2). Over-voltage protection: If the output exceeds the set limit of voltage, the VLF hipot test set will shut-down to protect itself, the actuation time is less than 20ms.

3). Over-current protection: VLF hipot test set is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.

4). A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.

2. High Voltage Insulation Resistance tester:

Feature

● Designed in strict accordance with safety standards, output voltage: 500v 1000v, 2500v, 5000v, 10000v.

● This instrument automatically calibrates the function and automatically calibrates the accuracy before testing.

● This instrument has the actual test product charging voltage measurement function, leakage current measurement function, automatic discharge function.


● It can automatically measure and memorize R15S, R60S and R10min values, and automatically display the polarization index (PI), the induced absorption ratio (DAR) test value and test time.

● Excellent anti-interference performance. When the interference current reaches 600mA, the instrument still guarantees test accuracy and strong anti-interference ability. It is especially used in 110KV and above large-capacity transformers and long-distance power cable power systems.

● Automatic discharge: The advanced high-voltage discharge technology is used to quickly discharge the capacitive sample. The discharge voltage is measured in real time during discharge (test sample voltage is 0v).

● Internal rechargeable lithium battery power supply or AC power supply, the real AC and DC does not affect the test accuracy.

● The analog pointer and the digital display coexist. The digital value reflects the accuracy of the insulation resistance of the test object. The analog pointer can reflect the dynamic change of the insulation resistance during the test.

● The alarm function during boosting, the buzzer warning has high voltage output, away from the sample, and the warning sound stops automatically after the test.

● Battery power digital display and undervoltage alarm protection.

● Intelligent battery charging management can effectively prevent battery overcharging.

●Automatic shutdown function: The instrument has an automatic shutdown function, and the measurement is completed for 5 minutes and automatically shuts down.

● Short circuit protection, the instrument will not be burnt out in the short circuit condition (use the voltage level within 2500V as much as possible in the nuclear phase).
