There is no escaping the fact that partial discharge is a complex phenomenon. The first step is to identify partial discharge activity, then to decide on the best course of action to take once partial discharge is detected. Both phases will require an experienced individual or consultant. But of course, it’s difficult to know what.. read more →

Welcome to the first instalment of our brand new ‘Ask the Expert’ series. IPEC recently spoke to Martin Judd, a partial discharge specialist at High Frequency Diagnostics and Engineering. HFDE is a Glasgow based consultancy business specialising in high frequency sensing and diagnosis of PD activity in high voltage equipment. Martin was one of the.. read more →

Historically, time-based maintenance of assets was the predominant tool used to ensure asset managers optimise asset life and repair defects. Many industries now favour condition-based maintenance, as it allows asset managers to determine asset health, and often the nature and severity of a defect before failure occurs. Overall, this improves reliability, performance and importantly, reducing costs. Implementing condition monitoring.. read more →

Thanks to the rise of big data, organisations now have the potential to gain a greater insight into asset condition. This is based on a larger and more complex set of data drawn from a variety of assets. Using the data gathered, asset managers can predict potential issues before problems arise. This allows them to.. read more →

Before we explain the difference between on-line and off-line partial discharge testing, let’s start with a little information about partial discharge, and what it is. What is partial discharge? Partial discharge is widely regarded as a predominant cause of long-term degradation and failure of high voltage (MV, HV and EHV) equipment. Partial discharge is often.. read more →
