Chinese launch for new PD products at Expo 2010 Shanghai

The latest UltraTEV Monitor™and UltraTEV Locator™ products feature both Mandarin Chinese and English user interfaces.

EA Technology is launching Chinese user interfaces for its latest UltraTEV Monitor™ and UltraTEV Locator™ Partial Discharge (PD) products at Expo 2010 Shanghai in June.


The world’s largest expo event is expected to attract 70 million visitors, during which the company will host a special Innovation in Power Engineering evening reception in the Liverpool Pavilion on June 22nd.


The new UltraTEV Monitor™ is being marketed as the most powerful system ever developed for monitoring PD activity in HV and MV substation assets over time. It has already been deployed by power asset owners and oil and gas producers across the world.


The new UltraTEV Locator™ is described as the world’s most powerful and versatile portable system for investigating and recording Partial Discharge (PD) activity in live MV and HV assets.


EA Technology director Neil Davies said: “Chinese-speaking countries are the fastest growing markets for our PD products, because they have been among the quickest to recognise the value of assessing the condition of live assets, as a means of increasing network reliability while reducing maintenance costs.


“The PD market is truly global, so we are developing other language interfaces for the UltraTEV Monitor™ and ultimately aim to make all our PD products multilingual.”


Now fully bilingual, the Chinese version of the UltraTEV Monitor™ and UltraTEV Locator™ will be marketed throughout China and the South East Asia by EA Technology’s own Shanghai office as well as its network of international distribution partners.


UltraTEV Monitor™



Developed by EA Technology in Capenhurst, UK, the UltraTEV Monitor™ is the only system in the world to use a combination of six sensor technologies to monitor PD activity, by measuring ultrasonic and Transient Earth Voltage (TEV) emissions, together with environmental conditions in the form of ambient temperature, surface temperature and relative humidity. Radio Frequency Current Transformers (RFCTs) are also used to monitor PD activity in cables.


The system uses a network of measurement nodes, daisy-chained over a single cable to a central hub, providing individual monitoring of PD activity in up to 250 substation assets simultaneously. In addition to detecting and locating PD activity on the surface and internal to components, it measures, records, analyses and provides management reports on changes in PD over time.


As an added bonus, the UltraTEV Monitor™ functions as a continuous PD alarm system, automatically searching for critical levels and trends in PD activity and transmitting alerts to asset managers over a choice of media, including email and SMS messages.


The Windows user interface provides access to the system’s web-enabled hub, which includes data storage and analytical software. Authorised users can access the system from anywhere in the world, using standard web browsers. Communications facilities are also provided via email, private networks and a range of mobile protocols, including 3G mobile broadband.

PD measurement has reached a new level with new, fully integrated UltraTEV Monitor™ system, capable of monitoring whole substations 24/7

UltraTEV Locator™


In one-shot survey mode, a single probe is used to detect and measure the presence of PD activity. Switching to location mode, both probes are deployed, using time of flight measurement to calculate the site of PD activity to an accuracy of 2ns (nanosecond), equivalent to 60cm. In comparative measurement mode, operators can measure surface PD activity in the form of decibel readings in the ultrasonic range and compare results with those taken from other assets.


All measurements taken by the system, including heterodyne of ultrasonic sound recordings, can be saved to the UltraTEV Locator™’s internal memory and recalled on the touch-screen display.


The battery-powered UltraTEV Locator™ is supplied in its own carry-case and is compatible with a range of accessories, including the UltraDish™ directional microphone and additional contact probe, to further increase its versatility.
