Properties
Retrofittable Voltage Detecting Systems for medium voltage (VDIS). Conversion of an HR or LRM interface into an integrated Voltage Detecting Systems according to IEC 61243-5 or IEC 62271-213.
Retrofitting without intervention in the switchgear
Retrofitting to all HR or LMR interfaces according to IEC 61243-5 resp. IEC 62271-213 possible
No battery required
Voltage test as well as self-test without battery or auxiliary voltage
Maintenance-free
No periodic maintenance test required due to permanent secondary-side insulation monitoring
Primary-side insulation monitoring of the capacitive divider
Early detection and indication of insulation losses in the primary C1 of the capacitive divider
Integrated self-test function
No external test device is required to test for absence of voltage. Integrated auxiliary voltage independent function test, according to patent DE103 04 396.
Integrated three-phase measuring point
The device has a three-phase LR measuring point for phase comparison, rotating field direction measurement, etc.
Retrofit defective HR interfaces
that no longer meet maintenance test requirements.
Integrated Y-interface
For connection of an external directional fault detection system or load flow monitor (e.g. IKl-23, IKl-50), connection via optional Y-cable.
