This article explores the latest methods for fault detection that can be used to improve the reliability and safety of electrical systems. Electrical faults are caused by disturbances within a power system network and these disturbances can result in severe economic losses. What is an electrical fault? An electrical fault is an abnormal condition within a power distribution system that results in improper system voltages and current flows. A fault in an electrical system can lead to extended ou...

ZPN Energy developed the concept of supplying EVs with stored energy, not just battery-to-battery refueling, but the concept of having a reservoir of energy that could be released through a sophisticated electronic power process at very high speeds - anywhere we needed to do it, including off-grid. ZPN Energy loves the idea of harvesting solar and wind power to propel cars and vans, as they know that the sun doesn’t shine, and the wind doesn’t blow every day. However, the company fe...
