Non Contact High Voltage
Sensors are useful, handy and safe device to detect presence of voltage by
proximity. The ‘Sensor’ need not touch live conductors and should always be
used with a ‘Hotline Stick’ (preferably a Fibre Glass Pole) suitably rated
for the system voltage under test.
The Sensor has selectable Voltage range settings (6
ranges in Model - 275 HTS and 2 in Model – 132 HTS). The sensitivity
selectors can be chosen depending upon distance between ‘Sensor’ and the
The internal circuitry triggers the audible and visible
(Buzzer and Neon) ‘ALARM’ when the sensor is brought in the radiated field.
The radiated electrical field increases/decreases with variation in
potential present in the conductor.
