Application

In order to measure voltage and or PD on DC test systems an appropriate divider fulfilling the specifications acc. to IEC 60060-1 and IEC60060-2 is required.

Mohaupt dividers and coupling capacitors do fulfill this specification.

Dividers/coupling capacitors can be extended by a blocking impedance to act as a PD filter.

Of course the capacitors are capable to withstand transient voltage stresses in case of flash overs.

All dividers/coupling capacitors can be equipped with any type of PD measurement equipment acc. to IEC 60270.

The PD equipment itself is available at Mohaupt as a trading product. Mohaupt recommends the use of Omicron PD equipment: Omycron Energy

Benefits

  • Multiple functions in one unit: voltage divider, coupling capacitor
  • Compatible with all kind of PD equipment
  • space and cost efficient
  • reliable performance / withstands transient voltages
  • small dimensions and weight, due to modern insulation materials

Technology

Mohaupt voltage dividers/coupling capacitors are built in the latest insulation technology: Insulation materials used are Jarylec and Polypropylene film stacks. This gives a maximum of insulation performance at small size and high capacitance.

Furthermore, the losses (tan delta) are reduced to a minimum (<10-4). In addition the capacitive branch is graded by an ohmic column to achieve excellent voltage grading during operation and transient stress.

For safety reasons DC dividers/capacitors are equipped with an galvanic ground connection at the the low voltage end.
