Wireless controller, a system implementing a wireless controller and a method which allows wireless control of high voltage test modules utilize wireless networking technology for the control and monitoring of High Voltage test equipment providing, for example, a completely galvanically isolated controller for High Voltage test modules. Utilizing wireless networking, with controller/regulator tied as talker/listener to reduce possibility of outside access to local network. Controller may be battery powered to provide full isolation of user from high voltage equipment. Other accepted group members can be added to monitor operations remotely with minimal possibility of outside intervention.
