The Nova 1401-LCT is an automatic dielectric breakdown tester. The tester performs the dielectric breakdown test on film insulated magnet wire according to NEMA, IEC, and JIS specifications. The tester has a test voltage range up to 20,000 volts at 50/60 Hz. The rate of voltage rise are (20, 50, 100, 250, 375, 500) volts per second.
In the Auto mode the test automatically stops and the dielectric breakdown voltage is captured and displayed. In the manual mode, the test voltage can be selected through a potentiometer for constant voltage testing of the specimen until failure. A timer indicates the test time of the constant voltage test.
The tester has a large clear polycarbonate test compartment with two safety switches. A mechanical contact specimen holder plugs into the high voltage terminals in the test compartment for testing twisted pair specimen. The dielectric breakdown test voltage is displayed until it is reset by the operator. Optional fixtures allow the Nova 1401 to test tape, films, or connect to other test fixtures such as ovens or humidity chambers.
