compliance could void the user's authority to operate the equipment
IC Warning Statement
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more
than that necessary for successful communication.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.

1. What does the UltraTEV Plus² do?
The UltraTEV Plus² is a versatile hand-held tool used to easily detect and classify Partial
Discharge (PD) in a wide range of electrical equipment.
The UltraTEV Plus² uses inbuilt TEV and Ultrasonic sensors and external accessories to
detect the presence of potentially damaging PD in switchgear, cables and overhead line
equipment.
The UltraTEV Plus² brings together three complementary sensor modes in a single hand
held instrument by regularly checking switchgear while it’s in service using the UltraTEV
Plus2, failure risks can be identified and action taken to avoid faults and downtime.
Algorithms and analysis capability built in to the UltraTEV Plus² provide vital insight,
classifying what you find to support the decisions you make and deliver the outcomes you
need. It’s never been simpler to interpret what you’re seeing and choose a course of action.
The UltraTEV Plus² records measurements at the touch of a button. Internal storage can be
used to provide access to historical data while you’re out in the field. Capturing what you’ve
measured allows you to see trends in the performance of your network.

3. Important Information
The UltraTEV Plus2is designed for use at ground potential only.
When testing electrical plant ensure that the metalwork is earthed
before taking any measurements.
Maintain safety clearances between structures at high voltage and
the instrument, its probes and the operator at all times.
RFCTs, connecting leads and test equipment do not provide
protection against high voltage.
Under no circumstances are earth/ground connections to be
loosened, disconnected or otherwise altered to allow use of this
equipment.
Adhere strictly to local safety procedures.
Do not make measurements when there are electrical storms in the
vicinity.
Do not make measurements immediately following the energisation
of a circuit.
Do not disturb plant during measurements either mechanically (e.g.
by shaking or striking it), electrically (e.g. by increasing the voltage)
or physically (e.g. by applying heat).
Do not operate the instrument or its accessories in an explosive
atmosphere.
Mains supply voltages are present within the battery charger.
This unit contains no user serviceable parts, always return to EA
Technology or your local distributor for service and repair.
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.

4. Non-Intrusive Detection of Partial Discharge
Activity
4.1 What is Partial Discharge?
Partial discharges are electrical discharges that do not completely bridge the insulation
between electrodes. The magnitude of these discharges is usually small, however they
cause progressive deterioration of insulation that may eventually lead to failure.
Non-intrusive partial discharge detection provides a means for identifying these potential
sources of insulation failure. If not detected the discharge may result in failure causing not
only in loss of supply to customers and damage to plant but could also endanger staff.
4.2 How can Partial Discharge be detected?
A partial discharge emits energy in various ways and produces a number of effects which
can be detected:
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 Plus2has specifically been developed to enable electromagnetic and ultrasonic
activity to be detected in a single simple to use instrument.
4.3 Airborne Ultrasonic Discharge Activity
Acoustic emissions from partial discharge activity occur over the whole acoustic spectrum.
Audible detection is possible but depends on the hearing ability of the individual. Using
an instrument to detect the ultrasonic part of the acoustic spectrum has several
advantages; instruments are more sensitive than the human ear, are not operator
dependent and are more directional when operating above the audible frequency.

The most sensitive method of detection is using an airborne ultrasonic Microphone centred
at 40 kHz. This method is very successful at detecting partial discharge activity provided
there is an air passage between the source and the Microphone.
4.4 Electromagnetic Discharge Activity
When partial discharge activity occurs within high voltage switchgear, it generates
electromagnetic waves in the radio frequency range which can only escape from the inside
of the switchgear through openings in the metal casing. These openings may be air gaps
around covers, or gaskets, or other insulating components. When the electromagnetic
wave propagates outside the switchgear, it produces a Transient Earth Voltage (TEV) on the
metal casing of the switchgear. The Transient Earth Voltage (TEV) is only a few millivolts,
of short duration having a rise time of a few nanoseconds and can be detected non-
intrusively by placing a TEV probe on the outside of the earthed switchgear whilst the
switchgear is in service.
4.5 Cable Partial Discharge Activity
When a partial discharge event occurs in a cable, there will be a resulting current pulse
coupled onto the earthed sheath of the cable. These pulses will propagate away from the
discharge site in both directions. Once the pulse reaches a change in impedance at a cable
joint or termination, a partial reflection occurs. This results in the pulses travelling back
down the cable several times (depending on the cable length) as they decay away. The
current pulses can be detected non-intrusively using a Radio Frequency Current
Transformer (RFCT) sensor placed around the cable earth strap.
