The Westminster Beacon Voltage Detector is a capacitive type voltage detector and is designed for use on a.c. electrified lines.

There are two types in the Beacon series, the 5- 12 kV voltage detector and the 10 – 36 kV voltage detector. The thresholds for which are calculated from 10% of the maximum working voltage and 45% of the minimum working voltage. The Westminster Beacon Voltage Detectors are designed to be used with customers? existing operating sockets and earthing poles, although these can be purchased along with the beacon if required. The testers are colour-coded, yellow for the 10- 36 kV and red for the 5- 12 kV for easy identification.

The Westminster Beacon voltage detector must be checked for proper operation before and after use. Press the black ON button, and the green LED will light up and remain illuminated for 5 minutes. The detector cannot be turned off until the cycle has finished. This function prevents the battery from discharging accidentally. Press the TEST button to prove the testers function using the internal test facility.


Voltage Operating Range:10- 36kV
Threshold Voltage:3.6- 4.5kV
Part Number:EFV-17201
