Abstract
A system and method for detecting the connectivity of an absence of voltage detector to the source of power to be detected has a first terminal wire connected to a first terminal and a second terminal wire also connected to the first terminal. An RF signal is placed on the first terminal and then its presence is detected on the second signal wire. This method and system can also be placed on each phase of a three phase system.
Claims1
A method for detecting the absence of voltage using an absence of voltage detection device comprising:
- initiation of a sequence by the user;
- checking a battery of the absence of voltage detection device;
- checking for a safe voltage threshold;
- checking a sequencer and oscillator of the absence of voltage detection device;
- performing a connectivity test via an RF generator connected with two leads per phase to a power source to be measured but one lead per phase to the RF generator;
- performing a voltage measurement test;
- and
- repeating the sequence of steps above.
