1kV – 40kV, Multi-Range Voltage Detector (F-1)

MULTI-RANGE VOLT DETECTOR (MRVD) 1-40KV, To confirm that a line is de-energized prior to performing maintenance on it, the Multi-Range Voltage Detector (MRVD) presents field practicality. A field intensity meter, the MRVD is calibrated to read approximate line-to-line voltage when connected to any phase conductor. It responds to the magnitude of the field gradient between its end probe and floating electrode (at the universal hotstick-attachment fitting). If the universal fitting is close to a ground, another phase, or another voltage source, the reading should tend to be high- if it’s close to a jumper or equipment of the same phase, the reading should be low. The MRVD gives a metered readout capable of distinguishing actual line voltage from static or feedover from an adjacent line. Readings from an MRVD can be compared with numerical certainty rather than the subjective judgments associated with "fuzz-sticking" or "glow-detecting." Since the MRVD is not a voltmeter, no specific accuracy is claimed by the manufacturer or can be assumed by the user. Available in modes for various ranges, the MRVD must be mounted on a proper length hotstick for the voltage class involved. Complete instructions are furnished with easy, illustrated step-by-step procedures. Internal circuit and pushbutton permit check before and after each use to confirm the operational condition of the instrument and battery.

URD Voltage-Presence Test on Elbows with Test Points can be performed only by Model C4030979 set at TP and fitted with its Straight Probe. Responds to the magnitude of field gradient between its end probe and floating electrode (at the universal hotstick attachment fitting). If the universal fitting is close to a ground, another phase, or another voltage source, the reading should be high. If it’s close to a jumper or equipment of the same phase, the reading should be low. Numerical readings can be compared with numerical rather than subjective judgments associated with “fuzz sticking” or “glow-detecting”.
