Product Advantages
- Leak-Proof Structural Design: Solves the oil expansion leakage issue common in traditional TDM series transformers by integrating the oil reservoir directly into the high-voltage casing.
- Enhanced Insulation & Compact Size: Employs multi-level insulation based on the "distance effect" principle, significantly improving dielectric strength while reducing overall volume and weight.
- Elimination of Internal Discharge: Utilizes metal fixed leads and pressure clamping mechanisms to prevent partial discharge and ensure stable high-voltage output.
Application Scenarios
- Power Equipment Withstand Voltage Testing: Used for conducting AC or DC high-potential tests on power cables, switchgear, and transformers to verify insulation integrity per industry safety standards.
- Electrical Component Dielectric Verification: Suitable for testing the breakdown voltage and leakage current of insulators, bushings, and other high-voltage components in manufacturing quality control.
- Laboratory High-Voltage Research: Ideal for research institutions and testing labs requiring a stable and portable 100kV AC/140kV DC power source for experimental setups.

Frequently Asked Questions (FAQ)
Q: What is the maximum DC voltage 5kVA/100kv Frequency AC Hipot Tester can generate, and what special precautions are required for DC operation?
A: This unit generates up to 140kV DC. During DC testing, you must loosen and insulate the short-circuit rod (D) inside the high-voltage casing and add an external current-limiting resistor and filter capacitor to prevent damage to the internal silicon stack.
Q: What are the specific insulation resistance values that this unit meets according to the factory inspection report?
A: According to the factory test report using a 2500V megohmmeter, the insulation resistance is 2,500 MΩ for High Voltage-to-Ground, Instrument-to-Ground, and Low Voltage-to-Gro.
