Model MWT-1 Magnet Wire Tester is a specialized high-voltage power supply
designed especially for performing the standard dielectric strength test on twisted
enamelled wires. The unit includes a test cage and all necessary equipment to
run the test, except a small quantity of mercury, fine steel balls or saline solution.
The test cage is equipped with a plastic 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. Mercury* cups are machined in a nylon bar,
which plugs into sockets within the cage. This permits easy removal of the cups for
filling, emptying and cleaning.
The maximum output voltage is 20kv, and there is an adjustable (automatic) rate-
of-rise of voltage to the specimen. Testing always begins at zero volts. When
breakdown occurs, the reading of the voltage at breakdown remains on the
voltmeter, although the high tension is automatically disconnected immediately.
THIS METER MEETS THE FOLLOWING STANDARDS:
