Megger Baker Power Packs
The Megger Baker power packs are high-powered impulse generators used to test very large, high-voltage windings.
Output ranges from 2,000 volts up to a maximum of 40,000 volts (Megger Baker PPX30: 30,000V; Baker PPX40:
40,000V).
Output for PP series power packs is controlled by a variable transformer and is dependent on a stable and proper
incoming line voltage. Output for PPX series is controlled by a precision regulated high-voltage power supply; output is
not dependent on the incoming line voltage.
These units perform Surge and DC HiPot tests when used with the Megger Baker ADX as the host for data collection.
They incorporate a supply monitor for safe operation from a well-grounded supply. In addition, 60kV rated test leads
are provided.
Voltage rise time is 100–200 nanoseconds, so the power packs comply with IEEE Standard 522-2004 and IEC Standard
34-15 when testing motor windings and coils.
