General Operating and Safety Information

Test Related Precautions
When testing from the switchgear, check that all proper lockouts are in place, and that proper connection is made
to the test points for the Asset being tested. Prevent connection to an adjacent live system during testing by
confirming with appropriate test instruments that the Asset circuit to be tested is dead.
Circuit connections, exposed conductive parts and other metalwork of an installation or equipment under test
must not be touched during testing.
Two-party operation is recommended only when using proper equipment (such as the remote E-Stop) and when
taking appropriate precautions so both operators are aware of all conditions at all times.
Always know what test is being performed and when. For example, do not adjust test leads when operating a

General Operating and Safety Information

Ensure Proper Grounding and Discharge after Conducting DC Tests
Upon completion of any DC Test described in this document, the device under test (DUT) should not be considered safe
to touch or handle until it has been completely discharged and solidly grounded.
When the DUT has been fully discharged and the tester voltage reduced to zero, the DUT should be solidly grounded.
The ground connection should be kept in place until the absorbed charge is completely dissipated. If ground
connection is removed before sufficient time has elapsed, a recovery voltage may build up, presenting a danger to
personnel who might touch the DUT.
For larger machines (greater than 2300 volts), a minimum grounding time of two hours or four times the DC test
duration—whichever is greater—is recommended to ensure sufficient energy dissipation. For smaller machines, a
shorter time may be acceptable. However, the user must be satisfied that no safety hazard exists before anyone
touches or handles the DUT.
The ADX provides a sufficient grounding path for winding discharge while the test leads are connected to the winding
and ground/frame. If the test leads need to be removed before the full discharge time has elapsed, secondary
grounding equipment should be attached between the DUT and station ground before removing the test leads. When
a proper ground connection is made, the tester can be safely disconnected from the DUT.
IEEE Std 95™-2002 provides detailed descriptions of the safety issues, along with guidelines for properly discharging
and grounding the device under test. Refer to this standard to ensure that you fully understand the process and the
proper steps to take to ensure safety to all personnel in the service area.
WARNING: DANGER FROM LOSS OF GROUND. Upon loss of the protective ground connection,
all accessible conductive parts, including knobs and controls that may appear to be insulated,
can cause an electric shock!

Configuration Options

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.
