Product Overview: A.B. CHANCE C403-1029 Multi-Range Voltage Detector 16 to 161kV
A.B. CHANCE C403-1029
MULTI-RANGE VOLTAGE DETECTOR (MRVD), 16-161KV
The Multi-Range Voltage Detector (MRVD) is designed for practical field use to confirm that a line is de-energized before maintenance. It functions as a field intensity meter, calibrated to approximate line-to-line voltage when connected to any phase conductor. The device measures the field gradient between its end probe and the floating electrode at the universal hotstick attachment. Proximity to ground, another phase, or voltage source may result in higher readings, while closeness to a jumper or same-phase equipment may cause lower readings.
The MRVD provides metered readouts, helping distinguish actual line voltage from static or feedover from adjacent lines. Unlike traditional methods like “fuzz-sticking” or “glow-detecting,” it offers more precise, numerical comparisons. As it is not a voltmeter, no specific accuracy is guaranteed. The MRVD is available in various range modes and must be mounted on a hotstick appropriate for the voltage class. Illustrated instructions are provided for easy setup and use, and a built-in circuit and pushbutton allow for an operational check before and after each use.
- Confirms that a line is de-energized before maintenance.
- Measures field intensity to provide an approximate line-to-line voltage.
- Distinguishes actual line voltage from static or feedover from nearby lines.
- Must be mounted on an appropriately sized hotstick for the voltage class.
- Features a pushbutton for checking operational status before and after use.
- Responds to the field gradient between its end probe and floating electrode at the universal hotstick attachment. A high reading indicates proximity to ground or other voltage sources, while a low reading suggests closeness to equipment or jumpers of the same phase. Numerical readings enable objective comparisons, unlike traditional methods such as “fuzz sticking” or “glow-detecting.” Comprehensive, illustrated instructions are provided for easy setup and operation.
