Capacitive High Voltage Detector Model 213HVD have been designed to meet the latest IEC Standards. It is self starting and automatically activated when the High Voltage is applied to the contact electrode. It can also be manually armed before use by depressing the TEST/ ARMING Button. This detector is intended for use on sinusoidal (50 or 60Hz) High Voltage Systems. Capacitive High Voltage Detector Model 213HVD systems voltage is 11kV. It is utilized to determine if a system is live or not, so that it may be safely earthed / grounded. Model 213HVD is designed for outdoor, but can be utilized indoor and in all wheather condition. It is housed in a rugged, reinforced nylon moulded casing and are shock drop and vibration resistant. Non standard threshold voltages can be customized to suit applications requirements. The High Voltage Detector have a low battery detection which inhibit manual arming when the battery is too low. The Nylon case is easy to clean and maintain and the High Voltage Detector is supplied with the cleaning kit. A visual indication shows when the High Voltage Detector is armed. When armed, the Green Leds flashes about twice per second. When High Voltage is detected, the RED Leds flashes about twice per second and the buzzer also buzz intermittently.
