Impulse Spark Tester
IT-25B - Clinton Instrument Company
While most military standards now favor high frequency spark testing over impulse spark testing, the IT-25B Impulse Spark Tester is available for use in some aeronautic applications that still specify the impulse method. The IT-25B meets the test requirements of military specifications MIL-C-13777E, MIL-W-16878, and NEMA standards for hook-up wire used in high temperature wire applications. This method is favored as an alternate to a wet dielectric test.
