The 700-D149 Series of AC Dielectric Breakdown testers represent a new
level of sophistication, flexibility and accuracy in dielectric testing
equipment. Each unit is equipped with a PLC-based control system that is
internally programmed to perform the D149 short-time test, step-by-step
test, and slow rate-of-rise test.
The unit can also be easily programmed to perform variations on these
test sequences. This dielectric testing equipment is equipped with a
voltmeter circuit that continually samples the waveform to determine the
breakdown voltage with the highest accuracy. The operator can control
all test parameters as required. At the conclusion of tests, all
relevant parameters (minimum, maximum, mean, and standard deviation) for
a series of tests on a sample are automatically calculated. Units are
available from 30kV to 100kV AC for a wide variety of applications.
