PP30 High Voltage Surge/ High
Potential Tester

The PP30 Power Pack is a high power
impulse generator used to test very large
high voltage windings.

an SKF Group Company

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

Whether you’re troubleshooting, manufacturing, or

rebuilding, Baker Testers consistently detects faulty

windings that other testers miss.
