The PP30 Power Pack is a high impulse

generator. It is 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 high

potential tests when used with the D12000, D12R

or AWA 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 (1,000’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

Whether you’re troubleshooting, manufacturing, or

rebuilding, Baker Testers consistently detects faulty

(0.1-0.2 microseconds), so the PP30 complies with

windings that other testers miss.

IEEE Standard 522-1992 and IEC Standard 34-15

when testing motor windings and coils.

The DC high potential test can also be

done using the PP30 along with the D12000, D12R

or AWA. Test voltage is set by the output control

from 2,000 volts up to 30,000 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

microamps.

In addition, the D12000, D12R, or AWA also

monitors current. This provides a redundant level

of safety for the DC high potential test.

The PP30 is housed in a mobile case on

pneumatic wheels. It provides power and

accessory connections from the D12000, D12R or

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.
