HIGH VOLTAGE
Peak Voltage Measurement
Precise measurement of high AC voltages according to VDE 0432 and IEC 60060 in connection with a high voltage divider
For the measurement, the principle of the capacitive or ohmic divider is used, which can be switched in the peak voltage measuring device.
Peak Voltage Measurement
In high voltage measurement technology, the peak value, or the effective value, of the voltage is determined in accordance with VDE 0432 or IECV 60060. The peak voltage measuring device from MPS Mess- & Prüfsysteme GmbH can measure these two values in connection with a high voltage divider (capacitive or resistive). In the event of flashovers in the high-voltage circuit, this is indicated in the SMG.

High Voltage Divider
For the precise measurement of high voltage with our peak voltage measuring device (SMG), a high voltage measuring divider is required, depending on the application, it can be offered in capacitive or ohmic design. Our high-voltage measuring dividers consist of an upper and a lower capacitor, the lower capacitor is very finely balanced in order to be able to maintain the required tolerance of <= 1% or <= 0.3%.
With these measuring dividers, in connection with the peak voltage measuring device SMG, high voltages can be measured precisely.
- Cpacitive from 50 to 1200kV
- Ohmic from 5 to 100 kV
- Further versions on request
Depending on customer requirements, the high-voltage measuring dividers are manufactured for different measuring voltages and capacities.
If the partial discharge is to be measured in addition to the voltage, the voltage divider is built with decoupling impedance.
