UltraTEV Locator - Partial Discharge (PD) Detector Brochure

UltraTEV Locator™portable partial discharge (PD) investigation system Locates, measures and records PD activity in all substation assets – including cablesThe UltraTEV Locator™ takes the investigation of PD activity to a new level of accuracy and sophisticationbene?tsLocating and measuring PD activity to identify faults BEFORE they lead to failures Recording and analysing PD activity to provide valuable information on the actual condition of assets More effective asset management, reliability, ef?ciency and safety, at lower costfact: 85% of disruptive substation failures are PD relatedfact: The UltraTEV Locator™ is the most powerfulmulti-sensor PD investigation system on the marketfeaturesAbility to pinpoint PD activity to within 10cmUltrasonic and TEV sensors for surface and internal PD Measures environmental conditions: temperature, pressure and humidity Records the severity of PD for diagnostic analysis Works with cables and overhead assets Tough, weatherproof case with built-in 8 hour batterythird generation technologyThe UltraTEV Locator™ is the product of EA Technology’s unique experience as a pioneer of measuring and interpreting Partial Discharge (PD) activity, gained over more than 35 years.?rst generationTEV instrumentsEA Technology’s PD Locator™ was one of the ?rst transportable instruments to record PD activity by measuring Transient Earth Voltage effects, using time of ?ight measurement to locate their source. Together with the PD Monitor™, it revolutionised the investigation of PD activity, with both instruments continuing to provide valuable service to this day.second generationUltrasonic + TEV instrumentsCombining ultrasonic and TEV measurement in single instruments like the UltraTEV Plus+™ has transformed the ability to detect and measure PD activity.third generationmultiple sensor systemsThe UltraTEV Locator™ is one of the ?rst of a new generation of asset management SYSTEMS, combining the functions of multiple PD instruments in a single package. UltraTEV LocatorTMPD investigation system including SIX sensors for improved accuracyThe UltraTEV Locator™ is a fully portable, multi-functional system for investigating and recording PD activity in unprecedented detail. It comprises a central unit with six sensors and dual probes, plus a range of accessory options to increase its versatility even further. This single package will measure the environmental variables which are known to affect PD activity, greatly increasing the value of the PD measurements.multiple featuresUltrasonic An Ultrasonic sensor is built into one probe, to detect and measure surface PD activity in the form of decibel readings A Flexible Sensor extended microphone is provided to enable measurements to be taken in apertures and hard to reach corners An Ultrasonic contact probe is provided to measure surface PD in sealed chambers such as cable boxes. The contact probe is magnetic for ease of application The central unit converts ultrasonic signals to the audible range, so operators can listen to PD activity over headphones TEV Transient Earth Voltage (TEV) sensors are built into each probe, to detect and measure internal PD activity Time-of-?ight measurement between the two probes enables the system to locate PD activity to within 10cm For ease of use, one probe can be attached magnetically to the asset under test RFCT PD activity in cables is measured using a Radio Frequency Current Transformer (RFCT) sensor which plugs into the central unitTemperature The central unit includes a sensor to measure ambient temperature An additional infrared probe can be plugged into the unit to measure spot temperaturesHumidity/Pressure The central unit measures the relative humidity of the operating environment The central unit measures the atmospheric pressure of the operating environment Take TEV readings of internal PD activity at various points on the asset in the form of numerical values Factor-in readings of ambient and localised temperaturesFactor-in atmospheric pressure and relative humidity, both of which can in?uence PD activityCompare results with those taken from other assets and historical records4 PD cable activityPD activity in cables is measured by the UltraTEV Locator™ using a plug-in RFCT sensor. Results are displayed as pC (pico-Coulomb) numerical values or in graphical form. 5 PD activity recordingAll of the measurements taken by the UltraTEV Locator™, including heterodyne sound recordings, can be saved to the system’s internal memory and recalled on the touch-screen display. Data can be downloaded via the USB port. The UltraTEV Locator™ is excellent value because it does the job of several instruments, all in one package - and a lot moremultiple functions1 PD locationBoth probes are switched to TEV mode to locate the source of PD activity, using time-of-?ight measurement between the two probes.The latest electronics enable the system to calculate the site of the discharge to an accuracy of 0.3ns (nanosecond), equivalent to 10cm. 2 PD one-shot surveyIn one-shot survey mode, a single probe is used in the same way as our UltraTEV Detector™ and UltraTEV Plus+™ handheld instruments, to detect PD activity.Both ultrasonic and TEV sensors are used. A simple traf?c light display indicates when threshold levels of PD activity are detected: green shows no signi?cant discharge, amber indicates some activity, and red warns that activity is at a level which warrants further investigation.Operators can use the factory-set threshold levels, or programme in their own. 3 PD comparative measurementIn comparative measurement mode, operators have a range of options: Measure surface PD activity in the form of decibel readings in the ultrasonic range, and compare results with those taken from other assets Listen to changes in PD activity in the form of audible signals through headphones (the system heterodynes the ultrasonic measurements for this purpose)operator friendlyIntuitive software accessed through easy-to-use touch screen menus.plug-in accessoryThe range of UltraTEV Locator™ functions can be greatly extended with this fully compatible accessory:1 Weatherproof carry case2 Can be carried halter-style or over-the shoulder 3 High resolution touch-screen - can be operated through the carry case cover4 Simple touch-screen navigation between functions, including browser for stored data ?le5 Port for a 50Hz sensor, which automatically synchronises the system with the local power frequency, referenced from any nearby lighting source6 USB port for easy transfer of stored PD activity data to PCs.

The ability to gather data on the condition of assets is a key part of the process of upgrading to Condition Based Risk Management™ (CBRM). This is EA Technology’s market-leading methodology, based on applying a Health Index to each asset and factoring in both the probability and consequences of their failure: an approach which is proven to improve asset reliability, availability and safety, while reducing the overall costs of asset maintenance and replacement.driven by customer needThe addition of the UltraTEV Locator™ and UltraTEV Monitor™ to our portfolio is the direct result of listening carefully to what customers require from their new asset management systems.tel +44 (0) 151 339 4181fax +44 (0) 151 347 2404email sales@eatechnology.comweb www.eatechnology.comEA Technology LimitedCapenhurst Technology ParkCapenhurst, Chester UKCH1 6ESblahdblahdesign 10444To ?nd out more, why not see the Podcasts at: www.eapodcasts.comglobal supportThe UltraTEV Locator™ can be supplied and supported anywhere in the world, through our network of international sales of?ces and distribution partners.We provide excellent lifetime support for this system, including:Installation and commissioning TrainingLifetime technical supportOnline data analysis and reportsOfficesDistributorsKey:
