Crusher Motor Powered By UMPS Drive
This article intends to establish how Primary Crusher motor will continue crushing for 15 minute with backup power through uninterrupted motive power supply (UMPS) drive in case of blackout without requiring to be oversized in its rating, so that no jamming occurs in crusher ....
Study of Inrush Current
The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…
