Dividers for Impulse Voltage Generators

When combined with our advanced impulse test systems, they are used to test HV apparatus such as Power Transformers, Instrument Transformers, Switchgear, Breaker, HV Cable etc. Tests are conducted with lightning, full or chopped waves, and / or switching impulses. HAEFELY HIPOTRONICS impulse generators integrate the highest safety systems which ensure a safe operation for personnel and test object.

CS External Damped Capacitive Impulse Voltage Divider

Product Brochure

The external damped capacitive impulse voltage dividers of the CS type can be used to measure full and tail chopped lightning impulses up to 1MV as well as switching impulses at voltage levels up to 750kV. This voltage divider serves simultaneously as a load capacitor for the impulse testing equipment. Provided with an adequate additional secondary part it can also be used for AC voltage measurements.


CR Internal Damped Capacitive Impulse Voltage Divider

Product Brochure

The internal damped capacitive impulse voltage dividers of the CR type can be used to measure full and tail chopped lightning impulses as well as switching impulses up to the highest voltage levels. This voltage divider serves simultaneously as a load capacitor for the impulse testing equipment. Provided with an adequate additional secondary part it can also be used for AC voltage measurements.


CZ Optimal Damped Capacitive Impulse Voltage Divider

Product Brochure

The optimal damped capacitive impulse voltage dividers of the CZ type can be used to measure full and tail chopped lightning impulses as well as switching impulses at voltage levels up to the highest voltage levels. (Identical design as CR type but damping resistor at test object instead of divider input what result in less reflection).This voltage divider cannot be used as a load capacitor for the impulse testing equipment. Provided with an adequate additional secondary part it can also be used for AC voltage measurements.


R Resistive Voltage Divider

Product Brochure

Resistive (low resistance) voltage dividers of the R type are fast and have good response parameters. Therefore they are normally used for measurements of full and front chopped lightning impulses or impulses voltages with steep wave fronts. The response time of the divider is in accordance with IEC 60060. Resistive voltage dividers are used when an additional capacitance in the test circuit is not permissible due to the slowdown effect on the rise time. This voltage divider cannot be used as a load capacitor for the impulse testing equipment.


RCR Universal Voltage Divider

The damped capacitive universal voltage dividers of the RCR type can be used to measure full and tail chopped lightning impulses as well as switching impulses up to the highest voltages. Provided with an adequate additional secondary part, it can also be used for the measurement of AC voltages as well as for DC voltages thanks to the additional ohmic parallel branch. This voltage divider serves simultaneously as a load capacitor for the impulse generator.
