Megger VCM100 Calibration Meter

Megger VCM100 Calibration Meter

The Megger VCM100 is a calibration meter suitable for verifying the calibration of Megger and Foster oil test sets. The VCM100 meter will enable the high voltage output to be checked, traceable to national standards, and is suitable for all recent laboratory models of Megger and 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 Megger VCM100 meter is supplied in a protective bag.

Megger VCM100 Key Features:

• Allows a quick check of high voltage output to be performed
• Tests up to 100kV at an accuracy of 3% of full scale deflection
• Analogue display marked from 0 to 100 kV with 2 kV divisions.
• Easy to read mirror arc display with tolerance bands

New versions of the Megger OTSAF are programmed with a test sequence suitable for using the Megger VCM100. This sequence causes the output of the oil test set to ramp up from 0 kV to the maximum voltage value, pausing at each 10 kV point for 10 seconds to allow the calibration to be checked.
