Hello All,
The project is to refurbish a large 5500HP,4kV Brushless Sync motor and convert the motor protection controls from the induction discs to our standard relay protection scheme for MV sync motors using the Multilin SR469/SPM relays.
The 4kV motor is fed directly from a captive stepdown...
I have a power system infrastructure that effectively puts two 3000kVA, 13kV/2.4kV, Z1=5.55% and Z2=6.33%, in parallel via basically a main-tie-main configuration. It's not as "clean" an arrangement, due to several feeder breakers that allow the tie between the two transformers. Old...
I'm trying to look for an alternative to grounding brushes that ride on a shaft of a steam driven compressor to dissapate electrostatic charges that are generating nuissance noise signals and in some cases a transient large enough to fry the analog signal input to the monitoring system. Brush...
