Non-partial Discharge Power Frequency Withstand Voltage Test Device for Transformer and Circuit Breaker
Working Principle:
Apply gradually increasing voltage to the test sample until it reaches the preset test value (such as 1.1 times the rated voltage).
If there are insulation defects inside the test sample, partial discharge will generate high-frequency pulse signals.
The signal is transmitted to the partial discharge detector through a coupling capacitor and impedance box, and after analysis, the discharge amount (pC level), discharge type, and location are determined.
If the discharge amount exceeds the standard limit (such as IEC 60270 standard), the insulation of the test sample is judged to be unqualified.
Main components of Non-partial Discharge Withstand Voltage Test Device:
1) Non-partial Discharge Power frequency test transformer: The device itself does not generate interfering partial discharge during the testing process.
2) Control box
3) Isolated power supply with filtering
4) Coupling capacitor
5) Protective resistor
6) Impedance box
7) Partial Discharge Detector
Control Box
Isolation Power Supply with Filter
Partial Discharge Detector
SF6 Gas Filled Transformer
Coupling Capacitor
Isolation Transformer
What is the difference between non-partial discharge power frequency withstand voltage test and traditional withstand voltage test?
Traditional withstand voltage testing only checks whether the tested object has breakdown, and non-partial discharge testing can detect potential insulation defects earlier. It can effectively ensure the safe operation of the power system.
Please inform us of the following information when contacting us, so that we can provide specific technical solutions:
What test objects do you need test? Such as Transformer,CT/PT,Circuit breaker,arrester and so on.
