CSA... I like your "true" stories! IKE43... The "32 GE electromechanical relay" calculates Watts, and can differentiate if its "flow" is away from or towards the generator! If either the PT's or CT's connections are reversed or their relative connections at the relay are reversed, then the...

abed77... DC Clamp-on ammeters cover even uA.

abed77... Since you asked how to fix the fault you must first find it. Following is the method I used, eliminating the dangerous method of disconnection. Using a DC clamp-on ammeter measure the current in each (+) (-) wire/lead connected to each terminal block ! Of course it would be better if...

abed... Search this Forum's archive for VKGupta's Aug 19, 2015, query, and BLANK's reply. Blank is the name of the only person the forum's security system doesn't allow me to mention !!! Regards, Phil Corso

Gentlepeople... Don't forget... Ambient Temperature of the battery's location is extremely important ! Regards, Phil Corso

Mani15... For your 1st calculation... the "Ideal Gas Law" calculation: a) You used the wrong units for "P" and "V". b) The two O2 tanks should be treated as one tank. c) "N" should be "n", d) The equation should have been PV = nRT. e) "N" is used in the equation PV = NkT...

Mani... If you prefer we can work it out off-forum and provide conclusion to the forum later. Contact me at [email protected]

Mani15.... Your "Ideal Gas Law" Formula is incorrectly applied ! For a simpler approach I suggest you search this Forum's Archives for Gi.Fi.E.S. pronounced "Jiffys".

Mani15... Your approach seems rather hectic, so, let's start with basics: Step 1) Before you consider any change of condition(s), what are the total moles of each gas at the temperature and pressure conditions you cited? Step 2) Will be given once you have presented the answer to Step 1 ...

Mr. Lodi... For increased safety: Assuming gen'r CB in question is connected to a "live" grid, then it is best to lower load-flow, with load PF as close to 1.0 as possible. Then open Gen'r stator CB at lowest current value reached before "reverse power" occurs. For the reason why, refer to an...

Jameson.... I suggest you contact the Gen-set supplier or suppliers to determine if their equipment can operate properly when powering VSD/VFD loads! Regards, Phil Corso

Ladies and Gentlemen, Attached is a 3-part pdf covering a Negative Sequence Effect on Single-Phase Loading of 3-Phase Gensets. Part 1 covers Double-Delta and Equivalent 3- Loop Solution Part 2 covers Mesh-Analysis to Calculate Loop-Currents Part 3 covers Delta-A Winding Dissymmetry...

Lee Tons... Since you are referring to an Engine genset, are you attempting to load it with a single-phase load ? Regards, Phil Corso

Indy... There are more than 1.000 references related to mixed cable-types, application-voltage, code restrictions, etc, in Control.Com archives ! First and foremost are those related to Electrical Codes, regardless of country. It's quite simple really... insulation of any cable (whether...

harsh1104[.. The rattling noise is indicative of multiple loose bars. What instrument are you using? Also, Voltage and HP or kW of motor Regards, Phil Corso ps: Is it your intention to keep the motor in service?

Indy... As long as the emergency stop device you use has a "Maintained" action" and not a "Momentary" action, i.e., can remain in the open or closed position, it can be easily fitted to the G120. Regards, Phil Corso

AAKhan... This post is for off-forum 'guests' that have asked me to explain the relationship between Affinity-Law and your specific problem, i.e., 'vibration' at initial actuation or introduction of water to the pump! The Affinity Law states that a pump's flow is proportional to its speed. But...

Heinz... All of it ! Are you referring to a specific transformer ? Or a some photo in your possession ? Is it related to specific equipment in the Power Plant identified with your forum name ? Phil

Heins... Be more specific. Phil

Heinz... Are you alluding to one of the earlier specifications regarding clamp and grounding ! Regards, Phil Corso
