Partial discharge (PD) is an early indication of the degradation of an insulation system for medium and high voltage networks. Insulation breakdown in an electrical power system can lead to high voltage asset damage, unplanned outages and production delays; with the potential for significant financial impact to your business. Luckily, PD can be identified quickly and non-intrusively – whilst equipment is live and in normal operation – allowing targeted HV maintenance and avoiding unnecessary equipment damage and downtime.   

It has been over one and a half decades since the publishing of the internationally recognised IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations in 2002. Since this time, the guide has been in the hands of specialist electrical engineers, and built into the software tools they use, having an unprecedented impact on the subject of arc-flash hazard assessment. So, with over 15 years of research and nearly 2000 additional arc-flash tests, what has changed?
