What are the safety devices on Cumins Diesel Generators
from 500 kva to 1500 kva.
It will depend on the controller used.
Most sets have at least-
Low oil pressure,
High engine temperature,
Low coolant level,
Over speed,
Under Speed,
Low AC volts,
High AC volts,
Over current,
Short circuit,
Weak battery,
Paralleling sets will also have-
Reverse power,
Loss of excitation,
Phase rotation,
Synch check,
Braeker fail to close,

What happens when the field of an alternator connected to infinite bus is suddenly removed?
Why we use d.c. meger in a.c. induction motor?
What is application of isolation transformer & How it works.
line vltage of three phase distribution transformer is 433v and phase voltage is 250v,but we required 230v for domestic distribution,then how we reduce phase voltage of transformer
We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
Generation of voltage for each phase are same of a turbogenerator.Although the short circuit current flow when two phase of turbogenerator are shorted(where current can't flow without potential difference),why?
