The PD2U offers convenient on-site testing
of electrical equipment. The basic unit can
be equipped with various options to suit
special measurement requirements.
This unit can be used with a full range of
preamplifiers covering the IEC60270
standard and ultrasonic frequencies up
to the UHF range (20 kHz-2 GHz).
Cable PD location (Option). Equipped with
a DSO board, the PD2U can be used to
locate partial discharge defects in power
cable. Using time domain reflectometry,
in which the PD and its “echoes” travel the
length of the cable under test, the PD2U
provides the proportional distance of the
PD fault along the cable. The additional
DSO board samples the PD signal at 100M
sample rate.
MUX4 (Option). 4-channel multiplexer for
testing three-phase equipment such as
power transformers. For each channel the
unit maintains an individual set-up and
calibration.
