DEHNcap/P LRM

  SAG DCA P LRM - 767 102



DEHNcap/P passive voltage indicator used for an encapsulated switchgear installation


DEHNcap/P Test Unit (Nominal voltages up to 230 V / 50 Hz)

  Test unit for testing DEHNcap/P voltage indicators for correct operation
  Plugs into 230 V socket outlets

Test unit for testing DEHNcap/P voltage indicators or other HR (HO) or LRM indicators for correct operation. Both HR and LRM devices can be used for testing.

The test unit is plugged into the mains socket outlet and generates both test voltages for HR and LRM systems.

Part Numbers

Nominal voltages up to 230 V / 50 Hz

  TG DCA - 767 110



Test unit for testing a DEHNcap/P passive voltage indicator plugged into a 230 V socket outlet for correct operation


DEHNcap/A Voltage Indicator (Nominal voltages up to 45 kV / 50 Hz)

  Safe verification of isolation from supply voltage
  User-friendly
  Easy to use

Self-testing element -- DEHNcap/A electronic voltage indicators have an integrated self-testing element. By simply pressing the test button, the electronic circuit is tested for correct operation. The self-test is automatically performed as soon as the indicator is switched on. The voltage indicator is only operational if the test button is pressed, i.e. the function test was performed successfully.

Part Numbers

DEHNcap/A HR

  SAG DCA A HR - 767 111

DEHNcap/A LRM

  SAG DCA A LRM - 767 112



Self-test of a DEHNcap/A voltage indicator


DEHNcap/IT Interface Test Unit (Nominal voltages up to 45 kV / 50 Hz)

  Easy and safe testing

Self-testing element - The DEHNcap/IT interface test unit has an integrated self-testing element. By simply pressing the test button, the electronic circuit is tested for correct operation. The self-test is automatically performed as soon as the indicator is switched on. The interface test unit is only operational if the test button is pressed i.e. the function test was performed successfully.

Part Numbers

DEHNcap/IT HR

  SPG DCA IT HR - 767 121

DEHNcap/IT LRM

  SPG DCA IT LRM - 767 122



DEHNcap/IT interface test unit allows to carry out maintenance tests on coupling systems of switchgear installations according to IEC/EN 61243-5 (DIN VDE 0682 Part 415).


DEHNcap/PC-LRM Phase Comparator (Nominal voltages up to 45 kV / 50 Hz)

  Easy and safe testing
  User-friendly
  Easy to use

By attaching two optional HR-LRM adapters (Part No. 767 133), the DEHNcap/PC-LRM phase comparator can also be used for phase comparison in HR systems. DEHNcap/PC-LRM is designed as a universal phase comparator in accordance with EN/IEC 61243-5 (DIN VDE 0682 Part 415) and detects zero crossings, but no voltage values.
