Multiple spaced windings in a coiled cable antenna improve ESD detection in small reactors while keeping the handheld sensor compact and durable.
Multiple narrowband receivers verify coincident, recurring partial discharge pulses across power cycles to reject radio interference and cut false positives.
Phase-locked timing windows and UHF detection separate true partial discharge events from RF interference in three-phase high-voltage systems.
Switching unit connects wire rods and stator core to terminals for simultaneous insulation testing.
Compressible conductive fibers establish electrical contact with insulated high voltage devices.
Rounded conductive surfaces and insulators prevent arcing damage when testing high-voltage isolators above 3,800V.
