Voltage presence indicators / warning devices and detectors are electronic equipment widely used as protective devices against electrical risks, their main purpose being to detect and indicate the presence of voltage in low, medium and high voltage installations.
Voltage detectors are devices intended to check the presence/absence of voltage in all types of power installations.
Detectors provide optical and acoustic indications of the presence of voltage in the inspected power installation.
Voltage detectors are made according of SR EN 61243 and are in a permanent stand-by state.
The detectors for LV power installations are multi-use (multi-testers) electronic devices designed for detection and indication of voltage presence and other functions: continuity, resistance, rotary field indicator, diode test.
