Lusco... If CSA has convinced you I'm too incompetent to provide an answer to your problem, then so be it. But, if you want to evaluate my competence yourself, then contact me at [email protected], and I will send you my resume ! Regards, Phil Corso

To the Moderator... I apologize for posting to the wrong thread. My eye-sight is not what it once was. To Lusco... Are you looking for a Figure-of-Merit, i.e., compare a machine's performance before and after some overhaul ? Or compare one machine's performance to another ? Or compare a...

Lusco... How much accuracy do you need? Phil Corso

MRabby.. Mr. CSA has provided you with an excellent methodical discussion related to your problem! Regards, Phil Corso

MRabby.... Can you relate incident(s) to: o Sync-Gen Load changes? o Atmospheric changes? o Ambient Temp changes? o Operational changes? o Time of day, wk, month, shift? o Coolant Changes? o Scheduled maintenance change? o What shows up on instrumentation? o Is a similar machine in operation...

Irsadansari.... The simple answer is yes. But, it must meet the recent (2020) harmonization of either USA's ANSI/ISA-84, or EU's IEC-61511. In my experience that means the DI via Fiber-optic, may have to be redundant. Regards, Phil Corso

Emilsg... Actually quite easy using what is called a "Symmetric-Logic-Function" ! Phil

Emilsg... It was neither overkill nor a typo! Used to monitor thermal runaway in a Hydrogen reactor in a US Refinery! Phil Corso

Thiagarajan Sriram Contact Electrical Maintenance Organizations familiar with Water-Washing High Voltage Systems. If you are interest evaluating or monitoring how often such maintenance should be done, contact me "Off" or "On" forum ! Phil Corso ([email protected])

RS... Re-configuration involves knowing the magnitude of phase-current unbalance. It can be determined using a math-tool called "Symmetrical Components" ! The procedure reveals an undesirable parameter called "Negative-Sequence Ampere Ratio ! Short of operating the Gen-set, there are at least 2...

SWAZ... NFPA-85, as well as 86 & 87, do not evaluate Voting-systems. But, it now recognizes SIS Voting Logic be included when considering Burner Management logic! My company can provide M of N voting systems for applications similar to the one you described . One particular application was a...

RS... This new approach will easily meet your House-Load ! And, I'm not proposing using transformers ! Phil Corso

RS... Expanding on the Hi-Leg Xfmr approach, are you capable, or have someone capable, of re-configuring the 6-winding's, now connected as a parallel 120/208V Wye, into a 240V Delta? Phil

RS... New approach... have you heard of a High-Leg, Red-Leg, or Bitch-Leg, 3-phase Distribution transformer? Phil

Your observed load of 12-kW exceeds the Rule-of-Thumb, i.e., a single-phase load should be limited to 30% of the 3-ph rating or 9-kW. Furthermore, a phase-phase winding actually has 4 sub-coils in series... 2-associated with the positive and 2 with the negative stator poles! Re-wiring for...

What is maximum house load, L1-N, L2-N, L1-L2, in Amperes or Watts

What is rated RPM?

RS... Just tell me what the parameters are! Phil

RS... Label the House Source Terminals L1h, L2h, and Nh. Then, your House's single-phase Load-voltages, that is, voltages between L1h-Nh and L2h-Nh are both 120V. The two are additive meaning the Voltage between L1h and L2h is 240V. It can be said their phasor's are 0 degrees apart. Now label...

RS. . . Q1) When you say "no load on L3" do you mean there is no load connected between L1-L3, nor between L2-L3, nor between L3 and neutral ? In other words, only single-phase 208V load connected between L1-L2 ? Q2) Can you provide a photo of the nameplate? Regards, Phil Corso
