HVD-QS High Voltage Indicator

HVD-QS High Voltage Indicator

The HVD Series High Voltage Indicator is designed for application in 7.2- 40.53 kV medium-voltage systems with rated frequencies of 50/60 Hz. It is suitable for installation in switchgear incoming busbars, circuit breakers, main transformers, and other critical points where reliable voltage presence detection is required. The device provides three-phase voltage indication and supports multiple LED display modes to suit various operational and safety needs. When high voltage is present, the LED indicators will flash according to preset conditions, offering clear and intuitive visual alerts to maintenance personnel and operators.

In addition to on-site indication, the HVD Series integrates configurable relay output for remote voltage presence alarm, control signaling, or fault protection linkage, enhancing both the safety and flexibility of the entire system. Its compact design, high reliability, and easy panel mounting make it an ideal solution for high-voltage distribution systems. Furthermore, the device incorporates a self-test function, allowing users to verify the indicator’s operational status at any time, thus improving system reliability and reducing the risk of operational errors.
