Claim 0:
1. A system for the verification of the absence of voltage comprising:
a first series of resistors and a first voltage limiter connected between a power line and a first voltage sensor and a such as to limit a sensed voltage to a set amount above a threshold set by a standard;
a first series of LC resonance filters connected between the power line and a RF signal generator wherein the RF signal generator and the first voltage sensor share a lead line;
a second series of resistors and a second voltage limiter connected between the power line and a second voltage sensor such as to limit the sensed voltage to a set amount above a threshold set by a standard; and
a second series of LC resonance filters connected between the power line and an RF signal detector wherein the RF signal detector and the second voltage sensor share a lead line and further wherein the system is configured to detect continuity to the voltage line by sending an RF signal generated by the RF signal generator through the first lead line and detecting it at the RF signal detector via the second lead line.
