In a typical generator, a prime mover (such as a steam turbine) supplies mechanical power to the generator, which is converted to electrical power and delivered to the electrical system. What Causes Generator Motoring? Generator motoring is a condition that happens when the […]
Generator Protection: Grounding and Ground Fault Protection
An important part of generator protection is that generators need to be grounded. And because they need to be grounded, generators are susceptible to ground faults. This article is going to talk about general case ground faults on a generator and the appropriate use of generator protection, and then talk about the specific case of […]
How to Detect Generator Faults with Generator Protection
Your generator protection must have a way to detect generator faults. A fault is any unwanted current flow in an electrical system. Faults can cause all kinds of problems for your generators, including current loss, interruption of power delivery, and damage to the generator due to overheating. There are three things your generator protection needs […]
