The 8175PL Series DC Hipot Testers The 8175PL Series dc hipot testers offer a 175 kV to 875 kV range in a convenient cascade design. These systems are SF6 insulated with each module individually capable of producing 175 kV at 17 mA. The standard power rating is 3 kW. Low leakage measurement, even with fluctuating line voltage, is possible with the standard 1% line regulation. The design also offers reversible polarity. This modular (expandable) construction favors the use of these portable testers in situations formerly requiring large mobile units. For example, when field testing, each technician can be equipped with one controller and as many modules as routine tests require. Then, for any non-routine higher voltage tests, additional modules may be assembled at the test site. A reusable shipping container is provided for each module for storage and transportation.

The 5250 primary cable fault locating system meets the demanding needs of electric utilities, electrical contractors, or any company testing medium to high voltage cables that require a highly portable, easy-to-use thumper system for quickly restoring electric service.

The 5250 utilizes an innovative, time domain reflectometer (TDR) along with the highest energy, battery-operated thumper on the market. The 5250 will reduce cable fault locating time by up to 80%. The 5250 can test faulted, loop feed underground residential distribution (URD) cable systems without having to disconnect transformers in an effort to sectionalize the cable fault between two transformers.

The battery powered 5250 combines a capacitive discharge, high voltage filter, digital TDR, and battery charger into one complete package. The operator can control all test functions through the digital TDR or by using the analog, high voltage controls on the 5250 front panel. The 5250 is connected to the cable under test using quick clamps and MC adaptors. Once the 5250 primary cable fault locator is connected to the cable under test, a trained operator can find faults in a matter of minutes.
