The Modiewark is a non-contact and contact voltage tester for detecting electromagnetic and AC electrical voltage sources from 110 volts to 750,000 volts at a range of 200mm to 300mm.
The Modiewark is a non-contact voltage tester which detects the presence of an alternating electric or electromagnetic field as both a proximity and touch device.
Its unique switching action allows for the identification of alternating currents at a distance between 200 mm and 300 mm from a voltage source from 110 volts to 750,000 volts.
The Modiewark has been used by industry professionals since the early 70’s for live or dead voltage determination of overhead power lines and underground power at the URD test point. Firstly as a proximity device to determine live or dead situations and then as a touch device to verify the tester has physically reached the AC field around designated mains under test.
The Modiewark can also be used indoors on the 240/110 volt setting, tracing voltage sources from power distribution boards and cable fault detection.
The unique nature of the sensor plate within the unit allows for directional checks such as checking low voltage when high voltage is nearby. Induced voltages on isolated conductors are checked by increasing the Modiewarks sensitivity.
Radiated field strength increases with voltage and decreases with earth shielding. The radiated field from a cable of closely bunched conductors supplied by three phase power tends to cancel. Detecting distance of a 240 volt single live wire is approximately 100mm and with a bunched neutral and earth, as a flexible cable, the distance is 50mm.
