ControlsGuy25 OP only sent Fault Chart showing kW and PF. Furthermore, there is no mention from anyone, except you, that loads are inductive. My calc illustrates Gen'r load consists of a large resistive component and a very small inductive component! BTW, have you noticed that OP no longer...

ControlsGuy25 Given Gen 4's Power output and pf are 234.6 kW and 0.909, respectively, then what is magnitude of the Inductive Load! Phil Corso

Jeff.3300 I suggest you resubmit your question as a new topic ! Regards Phil Corso

Controls.Guy... The Generator loads are not Inductive. They are 3-ph AC to DC Bridge Rectifiers.... which also distort generator current wave-shape ! Regards, Phil Corso

JSMHarish... The generators are rated ekW=1,045, but are operating at 20-30% of rating! Why? Usually, if not about 70%, then the present low-load operation will cause a host of problems! One, is the problem you are experiencing, another is reduced service-life! Is a Mfg representative on-site...

WTF?... Since we both have categorized the other, I would like to Make a Deal! I will send you my Resume! You will provide me with an SLD illustrating the Major Electrical Components in a plant encompassing the Hydrocarbon, Chemical, or Power Industries, that you: o may have worked in; o may...

JSMHarish... First, welcome to Control Automation. 1) Please provide generator parameters, kW, V, A, Pf, Hz, and operating hours since last maintenance, if any? 2) Did the problem suddenly appear or gradually over a long period of time? 3) Can you provide a chart listing kW and Pf for all 5...

@WTF.... You still don't get it! The product of VI can only be dimensioned as "Power" if I is at 0 degrees with respect to V! Regarding Malyah's statement, frequency of electrical current in order to maintain a desired level of power... you are right... frequency has zero, 0, nada... effect on...

@ WTF... Glad you asked! Since I didn't know anything about Malyah's electrical knowledge or experience I didn't respond to his frequency-related question! Nor would I use the disparaging term you did, when the purpose of this forum is to be-educating, not be-littling! I stuck to the original...

Malyah... Welcome to Control Automation. Well you certainly got my very old blood moving again! You are correct when you use the term "compensating"! But your error is the term "reactive power"! It should have been been "reactive component"! My dissertations concern the use of the term "power'...

Talal9001... 1. Welcome to Control.Com 2. What is the specific application on the motor? 3. Is it a first-time problem, that is, a start-up issue? 4. Has the problem persisted for a while in an operating facility? 5. If any, what is the Voting-Mode? 6. If any, what has a Vibration Instrument...

Jax316... All though the problem with your system was resolved, I'm still interested in the system's Electrical Parameters ! If you want my "WHY", then I suggest you use the Search Process (Magnifying Glass) located on the Headline of this topic, for the forum "ABB-6080! Unitrol !" Regards, and...

Jax316... I'm curious. Is the "LCI" furnished by ABB? Regards, Phil Corso

Jax316... Welcome to Control.com. Please provide system parameters... Volts, kVA, Rated Amperes, Excitation Volts, etc. Regards, Phil Corso Nevermind !

AhmedSoliman... If both sets of field-wiring are in the same terminal-wiring panel, then switch the wiring positions ! What happens to the readings? Regards, Phil Corso

BrownPaperBag... Welcome to Control.com This subject has been covered by several Contributors to Control.com Note the Magnifying Glass at the top of this page. Move the cursor to it and click on it, Then, go to "Search" and type in "Bernoulli"! Wikipedia is also an excellent reference. Regards...

AndreyG... Ans to Q1: Onlv if the valve is a one-way-valve ! Ans to Q2: I'm familiar with VFD's using torque-control to reduce Water-Hammer, common problem in water-distribution plants. Does your VFD have that feature? Regarding additional help I can provide the name of an Applications engineer...

AndreyG... Welcome to Control Com. I agree with your thought about the Brake Resistor. I suggest you contact the VFD supplier. The VFD might be configurable so that speed is reduced to zero and then the valve is closed! They might also provide one of their Field-techs, or know of one near your...

VBV... Welcome to Control.com: 1) Have you determined downhole cable impedance? 2) Do you know if overcurrent value is equal on all 3 phases? 3) Is downhole cable very long? 4) Is downhole cable 3-conductor or 4-conductor? 5) What are electrical parameters when motor is disconnected from...

Mohit... In a few days I will submit my opinion of what caused the ABB Unitrol-6080 failure, unless you advise otherwise ? Stay Well, Regards, Phil Corso !
