Product information "CAPDIS-PI-HR_RR4_universal"
Retrofittable Voltage Detecting Systems for medium voltage (VDIS). Conversion of an capacitive 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 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


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.

Extra-long connection cables

The connections for L1 and L3 are designed with a length of 300 mm in order to be able to connect interfaces that are far apart.
