The Megger VCM100 is a calibration meter suitable for verifying the calibration of oil test sets. The meter will enable the high voltage output to be checked, traceable to national standards, and is suitable for all recent laboratory models of Foster oil dielectric strength test sets such as the OTSAF series and the OTS auto and semi automatic series. The calibration meter fits in the oil test set chamber in place of a standard vessel.
The design ensures that the load to the transformer is similar to the load during an oil dielectric strength test. The voltage indication is viewed on an analogue display marked from 0 to 100 kV with 2 kV divisions. The scale also shows pass tolerance bands to enable a quick assessment of the accuracy to be made. The meter is supplied in a protective bag.
