IEC 61243-1 High Voltage Detector (up to 110 kV)

IEC 61243-1 certified high-voltage detector delivering accurate live-line detection from 10 kV to 500 kV in power plants, substations and industrial grids. Dual acousto-optic alarm: a super-bright 200-lumen LED combined with a 90-100 dB penetrating buzzer ensures clear signals even in noisy or bright outdoor environments. Built-in self-test: a full-circuit self-check before every use verifies the device is operational, keeping the detector safe and reliable for live-line work. High-strength telescopic design: epoxy fiberglass reinforced telescopic pole glides smoothly with outstanding dielectric strength and aging resistance, making the detector portable and easy to deploy. Advanced anti-interference circuitry: high-sensitivity sensing filters out external electric field interference for reliable results, while low-power design and long-life button cells extend standby time and reduce maintenance. 'Dual safety' design: pressing the ergonomic test button simulates a live signal and triggers both visual and audible alarms, confirming that sensor, circuit and battery are fully functional before actual testing begins. Designed for busy 500 kV substations and midday line maintenance, where visibility and audibility are essential safety requirements.
