Possible setting corruption, or, more likely, maladjustment in micro-processor based protection for the unit that tripped? System "bumps" are not all that uncommon, and generator protection settings may need subtle but important tweaks to reduce sensitivity and susceptibility to operating for...

Wrong forum for this question. CR "As iron sharpens iron, so one person sharpens another." [Proverbs 27:17, NIV]

The word should be "while" or "whilst," not "during." I'm with Bill, provided this is an air-cooled machine; better to prevent condensation on insulation while shut down than monitor insulation integrity 24/7. Besides, although there may be ways of doing this, I cannot once in my...

Agreed, cranky, as well as the fact that where used in radial only systems and not networks, only a limited number of customers will be interrupted, and as long as a sufficient local inventory of pad-mounts and human resources and work equipment is maintained the duration of the interruption...

Here are related but tangential questions for OP: [1] Are all valves motor operated with controls [and possibly even the power actuators themselves] located > 1 metre from any steam line? [2] If there are hand-operated valves, is each provided with an extension to keep the operator > 1 m from...

Doh! Sorry David, I don't know what I was thinking, and make no excuses. Thanks for that, Bill. Hmmm, I wonder if they used Q/S to derive W to get apparent power so they could bill for power factor itself, or if the calculation was performed some other way. CR "As iron sharpens iron, so...

Beginning of rant: I have heard this stated many times, and it's always made me scratch my head in puzzlement . . . and I've finally put two and two together about why. If one uses the classic real power / reactive power / apparent power triangle, and uses the decimal fraction ratio of...

You have reasoned it out correctly; jacketed would be a pointless waste of money and defeat the purpose of readily conducting lightning strikes to ground. CR "As iron sharpens iron, so one person sharpens another." [Proverbs 27:17, NIV]

Hi bacon, not much of a digression at all IMO; relates directly to the presence of step and touch potentials and the manifold facets of dealing with them. I always wore dielectric footwear, and the key-in-hand technique soon became second nature for me; the first time I got "the zap," it took...

From one of my previous related posts: "Grounding mats for people" will only be effective if the person in question is wearing conductive or 'non-dielectric' footwear, in other words WITHOUT the Greek letter Omega on it; I got by for many years of inspections and switching in high voltage...

Hey all, Last month I contacted the IESO here in Ontario, Canada, trying to get some information about system time error correction in the Eastern Interconnection. They got back to me today. This https://naesb.org/pdf4/weq_bps062520w1.pdf is the link to a public document published by NERC...

Sorry, didn't get what OP was asking the first time around. Provided there's ample cross sectional area in the tubes, I'd agree with LittleInch; why would there be very much pressure differential at all between the steam admission box and the condensate collection box? And why steam in the...

"ultra light voltage" I've never heard of that . . . ? CR "As iron sharpens iron, so one person sharpens another." [Proverbs 27:17, NIV]

In my world that was called swapping any two phases. The other technique [ reconnect a loads' phase A to Phase B, phase B to phase C, and phase C to phase A ] we referred to as "rolling phases" - and the "electrician with a clamp on ammeter and a screwdriver" was combined with a careful...

It depends . . . Is there any possibility of an out-of-phase condition developing between the incomers? Many of the industries I dealt with that were connected to feeders 44 kV and below took it on faith that they would never be supplied out of phase and therefore had no synch check facility of...

Administratively I'm not sure whether all the eyes have been crossed and the tees have been dotted, which also confuses me, bacon . . . but paperwork doesn't always comport with reality, at least in my experience. CR "As iron sharpens iron, so one person sharpens another." [Proverbs 27:17, NIV]
