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 2,000–40,000 volts maximum (Baker PPX30: 30 kV; Baker PPX40: 40 kV).
For ADX standard models with the Power Pack option, you can add low-impedance armature and coil testing
functionality to the host using a Megger Baker power pack with built-in impedance transformers (PP85 or PPX30A).
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.
