Scling... What did you learn from the systems History Recorder? Regards, Phil Corso

a_rishi... Welcome to Control.Com! What is your concern? Do you doubt it being Delta or Wye connected, or its capacity is 50 kVAr, then check it with a V, A, R, L, C, hand-held circuit-parameter tester! Regards, Phil Corso

Eng.Musaab... Now I'm very curious. My suggestion was going to be: o Shorter Switchgear line-up; o 7 symmetrically arranged Breaker Cubicles, instead of 8; o 3 Gensets, instead of 4; o 3 Sets of Synchronizing Gear, instead of 4; o 3 Sets of Genset Protection Gear instead of 4; o The larger the...

@ Eng.Musaab... Q1. Has anything been purchased already? Q2. Are you obligated to use 4 Gensets? Q3. Are the 4 Loads equal in size and demand Q4. Are you hampered by cost, space, or time for the total installation? Regards, Phil Corso

Eng.Musaab... I'm sorry but I'm neither a manufacturer nor a salesperson for a manufacture of the equipment you seek. I'm an Electrical Engineering Consultant with some 60+ years of experience! I mistakenly thought you needed help with equipment layout, not system components. Stay Well, Regards...

MiguelS... Welcome to Control.com! Are both motors coupled to the same shaft, that is, connected in tandem, but electrically powered Direct-On-Line (DOL)? If so, then I can tell you that you will have a problem, but it is easily corrected even if the motors are unequal in size! Regards, Phil Corso

Eng.Musaab... Welcome to Control.com! Presuming this is a short-lived, one-time project, with limited cost but without future concern, I suggest an SLD consisting of a single buss-bar line up, with one pair of Generator CB's on left-side, the other pair on right-side, and the 4 Load CB's between...

WTF?... The last one, of course! Phil

WTF? The best single-paragraph explanation for Isoch-Droop I ever read! Regards, Stay-Well Phil

Umairabbasi... Then I suggest purchasing a DC-DC Converter having the capacity and ranges you need! Phil

Umairabbasi... Q4) Do you have an electronics background? Regards, Phil Corso

Umairabbasi... Welcome to Control.Com! Q1) Do you mean you need to provide a 110 Vdc Load from a 125 Vdc Source? Q2) Are the Negative side of both Load and Source grounded/earthed? Q3) What is the maximum Amperes of the Load? Regards, Phil Corso

@ Jefferson & MWO Electrons drift a bit, but they don't travel thru any thing. I suggest you read some physics books! Regards, Phil Corso

Power factor correction JeffersonAirplane... Hi To correct power factor and consequently reduce the amunt of current the source has to provide for the active power (true work we want) and the reactive power. The way is to add impedances to the circuit to the load impedances. The added ones are...

JeffersonAirplane... Attached is an example of power factor correction that may help

Ghaith123 Not all electrical problems are related to electrical devices. So, please provide the steam flow records of the 2 paralleled machines before-during-after, the reported event! Phil Corso

Ghaith123... Your mention of a "400kV breaker" suggests a sketch, (preferably a print) of the system Single-Line-Diagram (SLD) would be helpful Do you have records of V, A, MW, PF, RPM or Hz, data for the 2 paralleled machines before-during-after, the reported event? Phil Corso

Samiullah... The reason I asked for more detail is that there is a Joint EASA/AEMT Study covering "Motor Rewinds" It's available thru Google! Regards, Phil Corso

Samiullah... Welcome to Control.com! One way I solved a similar problem was to connect it to a very low 3-phase voltage source. Then check for stator-current balance, hot spots, and unusual odors! Also it's very important to check how stator-iron is connected to the motor carcass. It should only...

Ghaith123... You asked for help, but seem reluctant to provide necessary data! Regards, Phil Corso
