Overview

The PP30 PowerPack is a high power impulse generator used to test very large high voltage windings. The output is controlled by a variable transformer from 2000 volts up to a maximum of 30,000 volts.

• The PP30 performs both surge and DC HiPot tests when used with the D12000, D12R or AWA (12kV instruments) as the control and display. It incorporates a supply monitor to insure safe operation from a well grounded supply. In addition, 60kV rated test lead cables are provided.
• The key element of the surge test circuit is a grounded grid hydrogen thyratron tube. The tube conducts very high peak current (1000's of amps). Such high instantaneous currents are needed to fully test the very low impedance windings of large motors or form wound coils. This current is only produced for a few microseconds by the discharge of a 0.1 microfarad capacitor.
• Voltage rise time is 100-200 nanoseconds, so the PP30 complies with IEEE standard 522-1977 and IEC Standard 35-15 when testing motor windings and coils.
• The DC HiPot test can also be done with the PP30 along with the D12000, D12R, or AWA (12 kV instruments). Test voltage is set by the output control from 2000 volts to 30000 volts. Current is displayed and a 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 10 micro amps.
• In addition, the D12000, D12R, or the 12kV AWA also monitors current. This provides a redundant level of safety for the DC HiPot test.
• The PP30 is housed in a mobile case on pneumatic wheels. It provides power and accessory connections from the D12000, D12R, or 12kV AWA as well as lead storage in a convenient portable unit. These features make the PP30 the most powerful and most advanced tester of its type.
