Offset Voltage - an overview ScienceDirect Topics

In an electrical system, a ground loop or earth loop occurs when two points of a circuit are intended to have the same ground reference potential but instead have a different potential between them. This is typically caused when enough current is flowing in the connection between the two ground points to produce a voltage drop and cause two points to be at different potentials. Current may be produced in a circular ground connection (ground loop) by electromagnetic induction. WebJul 9, 2024 · Potential induced degradation (PID) is a phenomenon that arises over time (months or even years). It may be negligible in the plant’s early stage but, over time, becomes more noticeable in advanced phases, causing important power losses. However, it’s not always easy to determine the main cause.
