In 2010 ohm labs took over support for the sensitive research electrical instrument service park divider line. The high voltage resistors are enclosed in an acrylic tube protecting them from dust and contamination.

In 2001 ohm labs took over manufacture and support of the julie research labs line of high voltage dividers. 100 v to 240 kv. High voltage resistor divider probes designed specifically for this purpose can be used to measure voltages up to 100 kv. In this facility we test and calibrate hv relays hv dividers hv probes spark gaps our fiber optic systems and hv digital voltmeters up to 450kv.

Calibration service dc high voltage nbs resistor voltage. A low voltage fan exhausts heat out the top of the divider. Division accuracy 20 ppm. Ross engineering corporation s high voltage calibration lab provides high accuracy capability for conducting tough reliability tests on all our high voltage devices.

All ohm labs high voltage dividers include iso17025 accredited calibration. Is one such company. High voltage calibration dividers are available from several companies usually those that also make the hv equipment requiring their use. Primary standard hv measurements.

Calibration period 3 to 5 years. 2500a high voltage divider series. High voltage divider micro precision calibration inc. High voltage divider and resistor calibrations author.

These hv dividers are also used as a way to measure the voltage of a high voltage source permitting the low end of the divider or its output to be connected.
