Measuring Partial Discharge

A two-day course from the pioneers of Partial Discharge (PD) technology, covering PD theory, PD detection instruments and PD measuring techniques. Detecting and measuring Partial Discharge activity gives a unique insight into the condition of MV and HV assets without the need for expensive shutdowns or invasive testing.

EA Technology pioneered PD theory and has developed an award-winning range of PD detection instruments and condition assessment techniques that help you achieve greater network reliability and prolong asset life, while at the same time greatly enhancing operator safety.

The course will introduce you to PD theory and the instruments used to measure PD in a range of equipment while explaining how to analyse and interpret the data you collect in greater detail.
