1Important Information
Care must be taken where work is performed in tight corners, where the
proximity of other earth planes will affect the reading. If possible
maintain a distance of more than 30cm from metal work which runs
perpendicular to the sensor faceplate.
Strong electromagnetic fields from mobile phones, RF transmitters,
VDUs and un-screened electronics in the frequency range DC to 1GHz
can have an effect on the readings. A measure of local fields can be
obtained by holding the UltraTEV Monitor in free-air at least 1 metre
away from any conducting surface.
The UltraTEV Monitor must be used in accordance with local safety rules
and procedures.
The UltraTEV Monitor is designed for use at ground potential only.
The UltraTEV Monitor™is designed and tested for indoor use only.
When testing electrical plant ensure that the metalwork is earthed before
applying the Nodes/Probes.
Maintain safety distances between structures at high voltage and the
UltraTEV Monitor and its operator at all times.
Do not operate the UltraTEV Monitor or its accessories in an explosive
atmosphere.
The UltraTEV Monitor contains no user serviceable parts, always return
to EA Technology or your local distributor for service and repair.
Do not hard wire the unit to the mains supply without providing a means
of emergency disconnection
In the event that the supplied wall plug is changed, EA Technology
assumes no legal responsibility for the safety of the instrument or persons
using the instrument.
EA Technology RFCTs are designed to be installed by suitably competent
operators on cable earth/ground straps which are suitably and efficiently
connected to earth/ground to maintain safety.
RFCTs, connecting leads and test equipment do not provide protection
against high voltage.
Operators must ensure that the cable earth/ground conductor is capable
of carrying the prospective earth/ground fault current for the time
required for protective devices to operate and without giving rise to
dangerous voltages or creating danger. The integrity of earth/ground
conductors and connections should be confirmed by the operator prior to
installation of the RFCT.

If PD is detected in plant connected directly to the High/Extra High Voltage power
system, the authority responsible for the plant should be notified immediately1

If no PD is detected, this does not necessarily imply that an item of HV/EHV Plant is free from PD. PD can vary in its
magnitude and severity and insulation structures can fail through causes other than those attributable to partial
discharges.
Under no circumstances are earth/ground connections to be loosened,
disconnected or otherwise altered to allow installation of this equipment.
It is acknowledged that connecting RFCTs within High Voltage cable
enclosures is the only means of connection in some situations. This is not
a preferred method due to the closer proximity to high voltage
conductors. To avoid danger, the operator’s safety rules must be observed
and careful consideration given to the placement, installation and ongoing
inspection of sensors, connecting leads and test equipment.
The operator is responsible for assessing risks and ensuring that the RFCT,
the connecting leads and the test equipment are connected safely.

2Introduction
2.1 General
Partial discharges are electric discharges that do not completely bridge the electrodes. The
magnitude of such discharges is usually small; however they do cause progressive deterioration of
insulation that may lead to eventual failure.
Non-intrusive partial discharge detection provides a means for identifying these potential sources
of insulation failure that result not only in loss of supply to customers, but can also endanger staff.
A partial discharge emits energy in the following ways:
Electromagnetic:
Radio
Light
Heat
Acoustic:
Audio
Ultrasonic
Gases:
Ozone
Nitrous oxides
The most practical techniques for non-intrusive testing are based on the detection of the radio
frequency part of the electromagnetic spectrum and ultrasonic emissions. The UltraTEV Monitor has
been specifically developed to enable electromagnetic and ultrasonic activity to be monitored in a
single simple to use instrument.
2.2 Airborne Ultrasonic Discharge Activity
Acoustic emissions from partial discharge activity are normally at a frequency too high for the human
ear, i.e. ultrasonic. As the partial discharge progresses towards failure the frequency sometimes
decreases into the audible range.
Using an instrument to detect the ultrasonic signal has several advantages: instruments are more
sensitive than the human ear, are not operator dependent and ultrasonic frequencies are more
directional. The most sensitive method of detection is using an airborne ultrasonic microphone. This
method is very successful at detecting partial discharge activity provided there is an air path between
the source and the microphone. However, in the case of sealed switchgear with no air path, an
ultrasonic contact probe can be magnetically attached to the external surface of the switchgear to
monitor internal activity.
2.3 Electromagnetic Discharge Activity
When partial discharge activity occurs within high voltage switchgear it generates Transient Earth
Voltages (TEV) and electromagnetic waves in the radio frequency range.
