The Criterion Instruments Limited Model AV-200VA-40-03 High-Voltage Test Set is a
specialized high-voltage power supply designed especially for measuring dielectric
strength on insulating sheets. The unit includes a test cage and all necessary equipment 
to run the test.

The test cage is equipped with a Plexiglas door so that the operation of the test may be
observed. This door is fitted with a safety interlock switch so that the operator cannot
receive an electrical shock. Inside the cage is a flat plate on which is placed the sheet and
is connected to the clip inside the cage.

The maximum output voltage is 20kV, and there is an adjustable (automatic) rate-of-rise
voltage to specimen. Testing always begins at close to zero volts (less than 400 V). When
breakdown occurs, the reading of the voltage at breakdown remains on the voltmeter,
although the high voltage is automatically turned off immediately.
