Voltage detecting systems

HR-ST

Voltage indicator fo high impedance systems

The voltage indicator type HR-ST is part of a portable voltage detection system, which is single-pole capacitively coupled to active parts.

Testing of the indicator - and the entire function of the unit - is possible with the HR / LRM function tester.

According to DGUV regulation 3 (table 1c), the unit is subject to the repeat test prescribed in a cycle of 6 years.

  • According to VDE 0682-415 (IEC 61243-5)
  • HR-ST: Voltage indicator for high-impedance systems
  • No battery supply
  • Voltage indication via flashing LED
  • Suitable for permanent operationb
