- The measured partial discharge intensity is
displayed either in pC or in mV in accordance with
IEC 60 270 / IS 6209 or NEMA 107. According to
IEC 60 270, the measured quantity shall be
multiplied by a correction factor, which considers the
circuit characteristics of the complete test
- With built-in correction circuit it is
possible to incorporate the correction factor into the
display. The actual partial discharge intensity can
then be read directly without the usual calculations.
At switch position "CORR", the correction factor is
- The PC pulses are tapped from
the analogue output terminal and displayed on the
- The power frequency test
voltage can be displayed with the partial discharge
pulses in an elliptical time-base and periodically
recurrent interference pulse can be blanked in the
oscilloscope display, automatically eliminating their
evaluation in the partial discharge meter.
- Built-in provision is available to conduct the
bridge type PD detection, which is useful to suppress
external noise having attenuation level of ³ 40 db.
