To confirm that a line is de-energized prior to performing maintenance on it, the MRVD presents field practicality.
Actually 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 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.
The MRVD must be mounted on 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 operational condition of instrument and battery.
