OVERVIEW
VOLTAGE DIVIDERS / COUPLING CAPACITORS
FOR DC APPLICATION
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.
