85% of disruptive substation failures are PD related, and once detected, PD will inevitably lead to asset failure. EA Technology is the world leader in PD detection, location and analysis, combining groundbreaking technology with unrivalled experience to provide the most accurate assessment of the condition of power assets and their potential for failure.

EA Technology PD Surveys are conducted by highly experienced staff, and analysed by experts using our extensive database of over 20,000 similar assets. PD Survey results are presented in an easy-to-understand ‘traffic light’ status report with clear and totally independent recommendations for managing your power assets based on their true condition.

PD Surveys can be undertaken at four levels and are carried out on live assets, so there is no interruption in supply.

Level 1: Initial PD Survey - a first pass survey to check for the presence of PD activity
Level 2: Detailed PD Survey - locates and quantifies PD activity to produce for detailed asset health report
Level 3: Ongoing PD Monitoring - measures and analyses PD activity over time to detect deterioration and raise the alarm if PD activity reaches a critical level
Level 4: Tailored PD Services - designed to fit your exact needs, including regular PD surveys and other condition assessments, to facilitate condition based asset management
