Electronic vs. Mechanical VLF Hipot Testers: Why Sine Wave Technology Is Revolutionizing Cable Testing
In the field of high-voltage insulation and medium-voltage (MV) cable testing, 0.1Hz Very Low Frequency (VLF) AC technology has become the globally recognized standard. By lowering the testing frequency from 50Hz/60Hz to 0.1Hz, technicians can perform effective AC withstand tests on large capacitive loads—such as XLPE cables and large generators—without needing massive, vehicle-mounted test transformers. However, […]
