3. Verify that the Installation is dead – DEHNcheck Voltage Detectors

HSA 194 High-Voltage Indicator
Nominal voltage range 110 ... 420 kV / 16.7 and 50 Hz
Easy and safe testing
• For contactlessly verifying that switchgear and high-voltage
overhead lines or centre-earthed monophase traction power
lines are dead
• Cost-effective / space-saving transport

General Information:
Temperature range – 25 °C ... + 55 °C, climatic category N
For use in wet weather conditions _
Indication Acoustic and visual
Self-testing element Yes

Special instructions for the use of HSA 194 110 420 SN7737
(Part No. 767539)
The device can be switched between the “climbing check“ mode (switch
position when climbing the tower) and the “110 ... 420 kV“ mode for
verifying that the overhead conductor is dead.
