HVI Metrohm 33/66kV High Voltage Detector
 
The Metrohm 33/66kV High Voltage Detector (HVD) is an essential safety instrument used to determine whether high-voltage systems are live or dead. Part of a comprehensive range covering system voltages from 11kV to 275kV, these units are constructed using rugged plastic moldings and PVC extrusions, ensuring excellent resistance to shock, drops, and vibrations in demanding field environments.
 
Introduction
 
High Voltage Detectors (HVDs) are widely utilized across the electricity industry to verify that high-voltage lines are de-energized before maintenance or repair work begins. This process is critical for ensuring the safety of personnel. Designed to comply with relevant IEC standards, these HVDs provide reliable performance on various system voltages.
 
Operation & Features
 
HVDs are battery-operated electronic contact devices that provide unmistakable status indications. By utilizing both visual and audible alerts, the device ensures the operator can clearly identify the status of the line even in challenging conditions such as bright sunlight or high background noise.
 
 
Dual Indication: Features super-bright LEDs for visual signaling and a high-intensity buzzer for audible alerts.
 
Configurable Thresholds: Activation settings (thresholds) can be set in accordance with IEC standards or tailored to specific user requirements for various system voltages.
 
Integrated Self-Check: All detectors feature a built-in self-test facility to verify the unit is operational both before and after use.
