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
For Application Information, please contact:

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.

EA Technology
UltraTEV MonitorTM Operating Manual
2178L014

The TEV signals are high frequency and therefore travel in the skin of the switchgear and can only
escape from the inside of the switchgear through openings in the metal casing. These openings may
be air gaps around covers, gasket materials or other insulating components.
In addition when the electromagnetic wave propagates from the partial discharge site it also
impinges on the metal casing of the switchgear producing a Transient Earth Voltage (TEV).
The partial discharge activity may be detected non-intrusively by placing a probe on the outside of
the switchgear whilst the switchgear is in service.
2.4 Cable Discharge Activity
Partial discharge can occur in voids in cable insulation in a similar way to internal discharges in
switchgear insulation. Cross Linked Polyethylene (XLPE) cable joints are particularly prone to partial
discharge, more so than Paper Insulated Lead Covered (PILC) joints, but less in both cases than the
cables themselves.
Because cables are usually buried access is only available from either end, so the previously
discussed ultrasonic and TEV measurement techniques cannot be used. Partial discharge activity
can be accurately assessed in a cable using ‘off-line’ measurement techniques. The most successful
of these is VLF mapping which will also give the location of any partial discharge activity as well as
magnitude. However taking a cable ‘off-line’ can be inconvenient and expensive, so partial discharge
can be detected in ‘live’ cables using a RFCT on the earth connection or strap between the cable
sheath and the earthed switchgear.

3The UltraTEV MonitorTM
3.1 Configuration Options
The UltraTEV Monitor™is available in a number of different hardware and software configurations
to suit different requirements.
The Hub is available in either a Wall-Mounted or Portable version. The Wall-Mounted Hub is designed
for permanent or semi-permanent installations and has the following features:-
Supports up to 60 Nodes
Connects to SCADA
Can control extra devices through SCADA interface
Wired LAN, Wi-Fi and 3G connectivity
Intuitive web interface, including simple system commissioning
The Portable Hub is design for temporary or semi-permanent installations and has the following
features:-
Supports up to 20 Nodes
Small, light and robust
Quick to set up
Simple to extract data
Wired LAN, Wi-Fi and 3G connectivity
Intuitive web interface, including simple system commissioning
3.2 UltraTEV Cloud versus Standard
The UltraTEV Monitor™ software is available in either a Standard or UltraTEV Cloud version. The main
difference between the Standard and UltraTEV Cloud version is that when using the UltraTEV Cloud
version, the user communicates with an EA Technology server. The server handles communication
with the Hub. With the Standard version, you communicate directly with the Hub.
The UltraTEV Cloud version does not store data on the device and requires an internet connection
to operate. Initially setting up the cloud based Hub will require a direct connection but after that,
you will be able to connect to the UltraTEV Cloud server from anywhere on the internet. This means
that no analysis functionality is present on the device itself; instead all analysis of data is performed
using the web portal to the UltraTEV Cloud.
The Standard version is used by connecting to the Hub. This can be done locally or through a remote
/ internet / corporate connection if available. Analysis can be done on the Hub directly. Alternatively,
collected data can be downloaded and analysed using the PDDAS application.

3.3 Portable System Outline
The UltraTEV Monitor system consists of a Hub Unit, laptop-style power supply and between 1 and
20 Nodes with associated peripherals. The Nodes each contain TEV and temperature sensors.
Further TEV, Cable PD and ultrasonic sensors may be connected to the Nodes to match the
requirements of the substation.
The Hub Unit is a specialised data acquisition unit responsible for data collection, processing,
interpretation and presentation to the user. In some variants the Hub may be responsible only for
controlling the flow of data from Nodes to the UltraTEV Cloud.
Figure 1: Portable UltraTEV Monitor Hub Unit1
3.4 Portable Power Supply Operation
The Power Supply provides power to the Hub Unit, which in turn powers the Nodes.
The green Power indicator on the Hub Unit is illuminated when the Power Supply is connected to the
mains.
There is a 5A fast-acting fuse on the power input to the Hub Unit. If the Hub does not power on
when connected to the mains, unplug any power cables to the Hub Unit and check if this fuse is
blown. A flat-bladed screwdriver is required to open the fuse holder.

3.7 Power Supply Operation
There are two formats of Power Supply available, both units have equivalent functionality with the
key difference being there supply voltage. The standard unit is powered by 110-230Vac whilst the
optional unit is powered by 48VDC.
3.7.1 Standard Power Supply (110-230Vac)
The Power Supply provides power to the Hub Unit, which in turn powers the Nodes, it also supplies
a mains phase reference signal.
There is no switch on the hub, and as such it should only be connected to a switched mains socket.
Do not remove the yellow and black Power In plug from the Power Supply without switching off the
mains first.
A Mains Power green indicator on the front of the Power Supply is illuminated when the Power Supply
is connected to the mains.
WARNING: Mains Power indicator is connected to the 100mA fuse. If the
indicator is off, switch off the Power Supply and check the 100mA fuse. If the
fuse has blown, the Power Supply could still be active even if the indicator is off.
The Power Supply is equipped with 5 fuses on the bottom panel (see Figure 6). The mains input is
double pole fused, protecting both the live and neutral lines. There is also a small fuse to protect
the phase reference transformer and the indicator LED. The power out to the Hub Unit has two
fuses, one on the 48V line out to the UltraTEV Nodes, one on the 12V to power the Hub Unit.

3.7.2 Optional 48V Power Supply
The 48V power supply provides the same output functionality as the standard power supply whilst
utilising a lower input voltage. Whilst the performance of the power supply is the same, the
connectivity is slightly different.
An external 110-230Vac to 48V (supplied with the unit) connects between the mains supply outlet
and the 48V input.
An external phase reference (supplied with the unit) must be connected between a mains power
outlet and the Aux-3 input.

Figure 9: Monitor Hub status LEDs
The functionality of these status LEDs is as follows:
Monitor Health: This green LED will flash while the system is starting up, and will be lit
solidly while the monitor is functioning.
Alarm/SCADA: These LEDs indicate the state of the Alarm and SCADA Output contacts.
These are normally in the “Clear” state (Section 8.1) and the corresponding LED will NOT be
illuminated. If any of the contacts change to the active state, or an Alarm condition is
detected, the corresponding LED on the front panel will light red. The following
functionality is preprogramed for each output:
oAlarm: LED will illuminate (or output will switch to an Alarm condition) when any
alarm is raised on the Monitor.
oSCADA Output 1: LED will illuminate (or output will switch to an Alarm condition)
