MPD 500

Partial Discharge Measuring System for Routine Test Applications

Partial Discharge Measurement

The MPD 500 partial discharge measuring system has been specially designed for providing fast and reliable results in a high­throughput environment. As a new member of the successful OMICRON MPD family with hundreds of systems worldwide in daily use,
the MPD 500 is the ideal solution for state-of-the-art routine testing, clear pass / fail decisions and most easy reporting.

Reliable evaluation of insulating systems

PD – Partial Discharges are defined as localized electrical

discharge that only partially bridge the insulation between
conductors, often preceding an insulation breakdown.
Therefore PD measurements are well established and widely
accepted for quality assurance and factory testing of medium­and high-voltage assets.

Modern PD measurement systems based on apparent
charge [pC], in accordance with IEC 60270, reveals faulty spots in
electrical insulations with a high degree of sensitivity.

RIV – Radio Influence Voltage measurements express partial
discharge activities as a voltage that appears on conductors of
electric equipment. The RIV value is displayed in µV according to
CISPR 16-1-1 and the still referenced NEMA 107-1987.

The most convenient way to measure PD

As the newest member of OMICRON's successful
PD measurement family, the MPD 500 benefits from the
experience of hundreds of MPD units in daily use by major
cable-, transformer-, and rotating machine manufacturers
worldwide.

By incorporating a wide range of leading-edge technologies,
highly sensitive and accurate results can be obtained by the
MPD 500 as easily as operating a voltmeter.

The user-friendly software provides full remote control of
the measurement devices and delivers very easy automated
reporting of PD / RIV measurements. The MPD 500 also holds
simultaneous multi-channel abilities, without the need for a
multiplexer.

Advantages of the intuitive MPD 500 software:

> Concise visualization of single as well as multi-channel

measurements

> User-friendly pass / fail functionality

> Detailed diagrams for in-depth analysis

For factory routine testing the conclusive pass / fail function is
ideal for fast decisions. Adjusting the thresholds is most easy, as
are the inception and extinction voltage.

Using the MPD's multi-channel ability allows to display multiple
actual PD measurement values simultaneously on one screen,
contrasting old-fashioned multiplexer solutions. This makes
the MPD 500 ideal for PD measurements in high-throughput
environments.

For advanced analysis classic ellipse and state-of-the-art
PRPD (ϕ-Q-n) visualizations show partial discharge activities in
real time at 25 frames per second.

Automate your reports

The optional comprehensive electronic reporting function
automatically provides a concise test protocol within seconds.
These reports contain information about the tested object, the
measurement, and all data in definable intervals, as well as
diagrams showing Q(t), U(t), and Q(U).

Individual screenshots can be inserted during measurement at
any time by simply hitting a hotkey.

Automated reports

Your benefits

> Economical – PD and RIV are combined within one

instrument

> Time effective, easy operation

> Decision support with clear pass / fail indication

> Efficient multi-channel testing with several results

displayed simultaneously

> Save time – Fast and easy automated reporting
