SEW0002-TELESCOPIC HIGH VOLTAGE DETECTOR UP TO AC 24KV
|
|
● Telescopic, compact, lightweight.● High voltage detection.● Low voltage detection.● Self test button feature.● Easy-to-recognize indication.● Waterproof.
The HD detect the presence of voltage in AC lines. An elongate insulation rod permits checking of high tension circuits at safe distance for voltage. The equipment is compact, lightweight, and easy to handle, and is also available for voltage detection in low-tension circuits.
●Working voltage range:
H.V. : 3kV~24kV AC....hold grip portion to detect.
L.V. : 80V~600V AC....hold nameplate portion to detect.
●Frequency : 50Hz / 60Hz
●Operation Test : (Initial voltage)
(a)When stretched, hold the grip portion.
Put the sensing tip in contact with the voltage :
250V AC ± 50V the LED and buzzer should work.
(b)When retracted, hold the nameplate portion.
Put the sensing tip in contact with the voltage :
80VAC or below the LED and buzzer should work.
●Operation start distance
Distance at which operation starts when front metal is brought near Ø5mm O.C. wire with grip portion meld by hand.
Where 24kV√ 3 (voltage to ground)....about 20cm.
Where 6.6kV√ 3 (voltage to... |
