ProxyVolt is a state of the art electrostatic power line warning system used for detecting the electrostatic field of any AC high voltage power line. ProxyVolt has been developing power line warning systems since 1999, when it embarked on a extensive R&D journey to develop an innovative, fully featured power line warning system. Born from a simple request from a client to protect his equipment and staff from coming into contact with high voltage power lines, today the ProxyVolt PV5008 is renowned for being an essential safety device for use within in the gas, mining, construction, transport, agricultural and government sectors both on a domestic and international scale.
