Power systems theory - generation, transmissions and distribution
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
ABB has produced a range of technical guides that offer concise explanations of the major technologies and technical issues in low voltage AC drives. ...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
The image (reproduced from IEC 60909) shows a typical fault in an ac system. From the illustration it can seen that there is an initial dc component ...
