11.1. VCM100D/VCM80D voltage check meters technical specification
The VCM100D and VCM80D are OTS accessories that enable the voltage output of the oil test set to be checked by
measuring the actual voltage at the HV electrodes. The calibration meters fit in the oil test set chamber in place of a
standard vessel and are designed to ensure that the load on the OTS transformer is similar to the load during an oil
dielectric strength test.
Meter type: Proprietary 100 kV/80 kV Megger OTS voltmeter with 4 seven-segment
digit digital readout
Accuracy at 23 °C: 2.0% plus 2 digits to 50 kVrms
2.5% plus 2 digits > 50 kVrms to 75 kVrms
3.0% plus 2 digits > 75 kVrms to 100 kVrms
(VCM100D only above 80 kV)
Operational temperature range: 0 °C to 40 °C
Storage temperature range: 30 °C to +70 °C
Operational humidity range: 50% RH at 20 °C
Storage humidity range: 93% RH at 40 °C
Safety: The meter is only approved for use with Megger oil test sets
Dimensions (W x H x D): 250 mm x 150 mm x 115 mm
Weight: 1.8 kg
11.2. Storage and transportation
The Oil Test Sets are precision instrument that generates HV to 100 kV and needs to be transported and stored
carefully.
For PB models, a transportation case is available as an option and required by customers wanting to transport the
OTS80PB or OTS60PB by road, rail or air. A soft, shoulder carry case is provided as an option with the OTS80PB or
OTS60PB. It opens up to facilitate running a test without removal of the instrument and provides two side pouches
for storage.
The unit should be stored in a room or area where the environment is within the temperature range
of -30 ºC to 65 ºC and maximum humidity of 95% at 45 ºC.
The OTS80PB or OTS60PB has batteries fitted it should be fully charged at least once every three months to maintain
full battery capacity.
