9 Partial Discharge (PD) Surveys for High Voltage Substations Expert independent condition assessment of your power assets Measuring partial discharge (PD) activity in your High Voltage/Medium Voltage (HV/MV) assets gives you a clear picture of the true condition of your power assets, so you can schedule your maintenance programme based on actual condition rather than time intervals, saving you both time and money. EA Technology can conduct a full PD Survey of all your power assets for you, giving you the benefit of a concise report, accurate results and expert analysis. benefits features mprove...

11 Testing your Protection Systems Combining protection secondary injection and trip mechanism timing tests Testing over-current protection relays and circuit breaker trip mechanisms has been recognised as a key part of any HV/MV switchgear maintenance regime. The best way to evaluate both your protection relays and circuit breaker trip mechanisms is to simulate the precise conditions that will occur during a fault and record the circuit breaker performance. Based on advances in testing technology, we are now able to combine both of these tests. All parts of your protection system are evaluated...

substations 17 substations 16 Earth System Whole Site Audit Earthing Protection Site Audit Process EA Technology’s Earthing System Site Audit service is the equivalent of an MoT inspection, to ensure that protection systems on private network operators’ high voltage installations will operate appropriately during a fault. This is essential to comply with current safety regulations, including BS 7430, and to prevent damage to plant and personnel. 1 site survey & measurement business benefits hole site survey checks the integrity of all W earthing systems Identify installations where remedial action...

19 Lightning System Audit EA Technology’s Lightning System Audit service provides independent, expert advice on the most cost-effective lightning protection systems to guard against damage to assets from electrical storms: and because we do not sell or install one-size-fits-all protection systems, they ensure the optimum balance between cost and risk mitigation for specific sites. Our recommendations ensure compliance with the British Standard Agency’s BSEN 62305 guidelines, which became a regulatory requirement in 2008. business benefits Recommendations are based on detailed site surveys by...

20 21 non-destructive VLF testing The Cable Partial Discharge Mapping Service™ works on the principle of energising HV/MV cables at Very Low Frequency (VLF), making the system very portable and requiring only a 13amp 240V supply. Our system is completely safe, non-destructive and has a 15 year track record of success, from the UK to the Far East. Cable Partial Discharge Mapping Service multiple applications Non-destructive Partial Discharge (PD) site testing of HV/MV cables Typical uses include: TM Measures and reports on the health of all cables up to 66kV. business benefits The service is effective...
