PD Instruments
Portable Switchgear PD Solutions
IPEC Ltd is a specialist engineering company based in the industrial heart
of the United Kingdom, who are well renowned technological innovators
within the of electrical engineering industry. Formed in 1995, the
company has made great advancement in its field and IPEC are now
leading specialists in Online Partial Discharge (PD) detection and
location, for MV, HV and EHV cables, switchgear and accessories.
Partial discharge is generally accepted as the predominant cause of long
term degradation and eventual failure of electrical insulation. As a result,
its measurement is standard procedure in the factory testing of many
types of high voltage equipment. In addition, partial discharge activity
can be tested for or monitored on in-service equipment to warn against
pending insulation failure.
IPEC currently have a live network of over 150 Permanent PD monitoring
Systems - monitoring over 5,000 electricity assets worldwide.
IPEC’s mission is to bring innovation, expertise, and outstanding
products and services to the electricity supply industry. A goal
IPEC continually reaches for through cutting-edge Research and
Development, Knowledge Consolidation, and Listening to and
Understanding customer needs and demands
Par�al Discharge Instruments
A significant propor�on of disrup�ve failure in substa�on
assets can be prevented through PD tes�ng. Periodic
tes�ng of electrical assets means that a poten�al fault can
be detected and repaired before it becomes a risk to
engineers or the surrounding environment.
All IPEC products are designed and manufactured in
accordance with ISO 9001 standards. IPEC have a
dedicated team of highly skilled engineers, who are able to
bring innova�ve ideas from concept to final product. IPEC
only work with carefully selected partners, ensuring the
highest quality in Bri�sh product manufacturing.
PD-SGS
PD Detector
PD-SG1
TEV PD Detec�on
Par�al discharge ac�vity inside metal clad high voltage
plant induces small voltage impulses called Transient Earth
Voltages on the surface of the metal panels. TEVs travel
around the surface to the outside of the switchgear, where
they can be picked up externally using a PD detector.
Ultrasonic PD Detec�on
Defects on the surface of high voltage insulators are prone
to a phenomenon known as surface tracking. Tracking
causes carbon deposits that build up over �me, ul�mately
leading to flashover and insula�on failure. IPEC’s PD
instruments are highly sensi�ve to the ultrasonic
emissions produced by tracking and enable the on-set to
be detected before insula�on failure.

PD-SG1
PD-SGS
PD-SGS is a dual transducer PD detector for switchgear. The instrument detects TEV
signals generated by internal discharge, as well as acous�c discharge generated by
surface tracking or corona. The device can measure TEV signals generated by
internal PD and it uses ultrasonic detec�on of surface PD ac�vity. The PD-SGS has
an integrated noise detec�on algorithm to avoid false posi�ves. Level mode and
trend mode can be heard through audible output, through headphones or built in
speaker.

PD Detector
PD Detector is a dual transducer test instrument, with data synchroniza�on, for
switchgear. The instrument detects TEV signals generated by internal par�al
discharge as well as acous�c discharge generated by surface tracking or corona. A
mobile device receives data directly from the instrument for display and
synchroniza�on with a central server. The user can log trend PD ac�vity against
par�cular assets and it can generate automa�c ‘high PD’ alerts to a management
team live from site.

PD-SG1
PD-SG1 is a dual transducer switchgear PD detec�on instrument. The unit detect TEV signals
generated by internal discharge, as well as acous�c discharge generated by surface tracking or
corona. The system uses two channels to acquire TEV signals, enabling accurate loca�on of PD in
switchgear.
The PD-SG1 has three modes: Level Mode, used to detect presence of both TEV and ultrasonic
ac�vity; Cycle Mode, Phase Resolved Par�al Discharge Display (PRPD) enables the user to verify PD
ac�vity is genuine and not from electrical noise interference before taking further remedial ac�on;
Precedence Mode, dual sensor precedence allows users to pin-point the source of PD ac�vity.
