1kV - 800kV, Super Voltage Proximity Tester
Catalog ID: H1990ST
- Non-contact unit reads field intensity to determine if line is energized or not
- Must select range based on expected voltage
- Separate Universal Adapter available
Lights blink and alarm sounds when placed in electrostatic field above trigger threshold. Five flashing red lights alert the operator. High-pitched tones also signal nearby personnel of present voltage that could be dangerous when applying temporary grounds or performing maintenance. Can be used to check overhead lines, in substations and around switchgear. Simply slips over the head of a standard 1-1⁄4"-diameter disconnect stick. Handy three-way switch permits selection of either the 1 - 100 kV or the 100 - 800 kV range for circuit being tested. Turns off unit to save the battery when not in use. 9-Volt alkaline battery readily installs by removing two knurl-head screws and sliding off the instrument cover. Test button checks both the battery and the tester. Depressing button activates signal circuits, sounding the tone and lighting the alarm lamps if the battery is good and unit operable.
