PP24 Power Pack

The PP24 is a high performance impulse generator that is capable of testing medium and high voltage windings. The output is controlled by a variable transformer from 2,000 V up to a maximum of 24,000 V.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The PP24 performs both surge and DC high potential tests when used with the AWAIV-12, AWAIV-6, D3R, D6R, and D12R as the control and display. It incorporates a supply monitor for safe operation from a well grounded supply. In addition, 45 kV rated test lead cables are provided.

The surge generator is designed to provide IEEE 522-2004 compliant test voltages. The key design element of the surge test circuit is it meets the requirements for IEEE 522-2004 compliant test voltages. The tester supplies 0.1 to 0.2 ?S voltage pulses to the coil or winding under test. Voltage rise time is 100 to 200 ns (0.1 to 0.2 ?s), so the PP24 complies with IEEE Standard 522-2004 and IEC Standard 34-15 when testing motor windings and coils.

The DC high potential (HiPot) test can also be done using these power packs. A test voltage is set by the output control from 2,000 V up to 24,000 V. Current is displayed and an overcurrent trip circuit monitors the test. If current exceeds the trip level, the test is automatically halted. In its most sensitive setting, the protective circuit will operate as low as 10A.

In addition, the host units monitors current. This provides a redundant level of safety for the DC high potential test.

The PP24 provides power and accessory connections from the host unit. These features make the PP24 a powerful and advanced impulse generator.
