PMC Calibration is excited to announce the acquisition of several Ross Engineering High Voltage Dividers. The models acquired include the VD-30, VD-120, and VD-195. Ross Engineering’s precision high voltage dividers are calibration standards that have expanded our high voltage testing capabilities to 195 kV. Any of PMC’s four locations can now test all of your Hipot testers, high voltage test sets, megohmmeters, and much more!
The Ross Engineering high voltage dividers have been used as primary voltage standards by leading manufacturers. Accuracy <0.1% DC, 0.5% AC at 60 hertz. The three basic parts of the test are the voltage source (Unit under test), a Ross Engineering Voltage divider and a high accuracy bench top multimeter. The Ross Engineering high voltage divider output difference is as small as 0.1V at any input voltage 1kV to 1000kV depending upon the model.
