The company’s Power Forensics™ service specialises in investigating the condition of HV and MV assets, using the latest laboratory techniques to understand how ass...

Cheshire-based power engineering company EA Technology has more than doubled international sales of its high tech products in the first quarter of 2010 – with China and Asia Pacific leading growth. In March alone this year, the company won overseas orders worth more than in the whole of 2008 for its UltraTEV instruments, which test for faults and measure the condition of high voltage eq...

EA Technology has added two new accessories to its range of UltraTEV instruments and systems for detecting, locating, measuring and monitoring Partial Discharge (PD) activity in MV and HV assets. The new PD Simulator™ is designed to train engineers in a safe environment how to detect, locate, measure and interpret PD activity, using any of EA Technology’s UltraTEV instruments and...

The latest and products feature both Mandarin Chinese and English user interfaces. EA Technology is launching Chinese user interfaces for its latest and 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 re...

In 2005, a European utility adopted best practice in condition assessment of substations with a particular emphasis on insulation condition and the detection of partial discharge [PD] in distribution substations. A transportable PD alarm system was supplied by EA Technology, and found immediate application in the detection of intermittent PD activity. The results were corroborated by comparing...

Over the past 30 years handheld instrumentation has been developed that enables the detection of partial discharge activity with the plant in normal service. The continuing challenge in making meaningful field based partial discharge measurements is to reliably relate the severity of any detected partial discharge activity to the risk of failure of the item under test. The risk will be a fun...

Imagine being a substation manager in a few years’ time. Wherever you are in the world, your web-enabled laptop will give you a detailed picture of the condition and performance of every switch, transformer and cable for which you are responsible, in real time. Plus it will automatically alert you about any component which is at risk of failure and may require active maintenance or repla...

Owners and operators of electrical networks have become increasingly interested in condition monitoring of high voltage electrical equipment. Major benefits have been obtained through preventing failures, reducing maintenance, operating costs and extending plant life. The use of testing, diagnostics and condition monitoring systems has enabled assessment of the condition of existing distributio...

By Charles Williamson, EA Technology Australia Owners and operators of high voltage networks are facing ever-increasing challenges to maximise utilisation of existing equipment and reduce operational costs whilst maintaining and improving system performance. Yet, they all have the same problem – an ageing infrastructure of equipment that has been installed and in operation for 20, 30...

By Simon GOLDTHORPE, EA Technology – UK; Charles WILLIAMSON, EA Technology Australia; and Simon HODGSON, Nortech – UK This article is based on a paper presented to CIRED 2009 in Prague. Partial Discharge (PD) is accepted as being one of the major causes of Medium Voltage (MV) switchgear failure [1 &2]. Over recent years non-intrusive partial discharge measurements have beco...

Recently developed techniques to measure the condition of live power assets are transforming the way assets are managed around the world. Converts report dramatically improved network reliability and better customer service at lower cost. So where is the evidence to support their claims? And what can Australia learn from it? By Charles Williamson, EA Technology Australia Just like...

By Charles Williamson, EA Technology Australia Just like people, assets age and deteriorate. And as with human medicine, there have been tremendous advances in recent years in the ability to diagnose the ailments suffered by assets in their early stages, enabling us to keep them healthy and productive for longer. The revolution in asset management is being driven by two factors which ar...

The new UltraTEV Locator™ is a fully portable, multi-functional system for investigating and recording PD activity in unprecedented detail. EA Technology has launched the world’s most powerful and versatile portable system for investigating and recording Partial Discharge (PD) activity in live MV and HV assets. Called the UltraTEV Locator™, the dual probe instrument featu...

EA Technology, in conjunction with the Energy Networks Association, held the 2nd Distribution Network Strategy Conference, Network 2010, on Thursday 4th February. The event was attended by 60 senior executives from the energy sector in the UK and internationally, many of whom also joined EA Technology at the Institute of Engineering and Technology’s Annual Dinner. This year’s event...

11/01/2010 The objective of this course is to introduce delegates to electrical power engineering and it is applicable to engineers working for owners and users of electricity networks including large industrial users of electricity up to and including 132kV. The course will cover all aspects of power systems engineering and will provide delegates with a sound foundation upon which the...

09/06/2009 EA Technology says its all-new UltraTEV Monitor is the most powerful and versatile system ever developed for monitoring Partial Discharge (PD) activity in HV and MV substation assets. 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. EA Tec...

27/06/2009 EA Technology has started running two day training and certification courses, which will enable companies to comply with new regulations on the safe handling of sulphur hexafluoride (SF6) gas, commonly used to insulate HV switchgear. The course is designed to satisfy the UK’s Fluorinated Greenhouse Gases Regulations 2009, which stipulate that anyone who recovers SF6 from HV sw...

23/07/2009 A new range of dual sensor instruments for detecting, locating and measuring (PD) activity in MV and HV assets is now available for power owners and operators in South Africa and neighbouring countries.
