    Abstract: A system for the verification of the absence of voltage has a first series of resistors and a first voltage limiter connected between a power line and a first voltage sensor and such as to limit a sensed voltage to a set amount above a threshold set by a standard and a first series of LC resonance filters connected between the power line and a RF signal generator. The system also has a second series of resistors and a second voltage limiter connected between the power line and a second voltage sensor and a second series of LC resonance filters connected between the power line and an RF signal detector. 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.
