High Voltage Tester

High Voltage Test Equipment: How This Catalogue Is Organised

Two hundred and thirty-six instruments, grouped into fourteen families. This page is the index to them: each family below is a working group of test equipment, and every product listed in this catalogue belongs to one of them.

Transformer and oil testing

• Transformer testers — turns ratio, winding resistance, dielectric loss, short-circuit impedance, tap changer analysis and the oil test suite.
• Instrument transformer testers — CT and VT calibrators, ratio and burden testing.

Switchgear, cable and line testing

• Switchgear testers — circuit breaker timing, loop and contact resistance, contact pressure and SF6 gas analysis.
• Cable testers — fault location, oscillating wave diagnostics and cable identification.
• Power line testers — insulator detection, salt density measurement and live-line insulation testing.

Protection, metering and power quality

• Protective relay testers — multi-phase relay test sets and secondary injection testing.
• Energy meter testers — portable meter testers, wiring checkers and secondary circuit measurement.
• Power quality analyzers — portable analyzers and waveform recording.

Earthing, capacitance and sources

• Grounding system testers — ground resistance, soil resistivity, ground grids and bonding.
• Capacitor testers — power capacitor testing, charge-discharge and overvoltage tests.
• Surge arrester testers — DC parameters, leakage current and counter testing.
• High current generators — DC and impulse high voltage sources, high current sets and temperature rise testing.

Batteries, general instruments

• Battery testers — internal resistance, capacity, discharge and lithium pack testing.
• Electrical test instruments — generator, line parameter, vibration and balancing instruments.

Every instrument in this catalogue is sourced from qualified partner factories in China, verified and tested against its datasheet before shipment and delivered with its test documentation. Houfeng is a trading company and supplier, not a manufacturer.
