Responding to Biswajit/Debabrata's 06-Apr-09 (06:52) query: Please furnish some detail on the "Flame Loss" detection system you use: a) Type and number at each burner! b) Self-checking? c) Purging media for flame detector sight-tube, if used? d) What applicable Standard do you...

Paru, most of the times the ingress of air occurs because of what is referred to as "breathing!" Breathing is caused by the daily change of temperature allowing the ingress of air through via top to tank flanges, insulator flanges, or piping above the oil level, especially those associated...

Paru, did you implement the precaution(s) inherent in my Jan remarks? Phil

Paru, is this the oil you referred to in your Jan-09 thread? Phil Corso

Vashim, search archive using Key Words like "NGT", "NGR", "Neutral Grounding", "Neutral Earthing!" If you are still unable to retrieve helpful information, then, contact me off-list! Regards, Phil Corso([email protected])

Responding to Vashim's 01-Apr-09 (10:32) query: The starting point is to determine the 6.9kV system capacitance to ground. Check the Control.com archives. If you are unable to find what you want, contact me! Regards, Phil Corso ([email protected])

Fiaz, 1) Make sure capacitor voltage is rated phase-to-phase. 2) See thread # 1026188112 ! Regards, Phil Corso ([email protected])

Responding to James' 13-Mar-09 (08:12) query... following are several ideas based on weirs, in ascending order of accuracy: a) Take the height of the outflow as if it were the "head" measurement of a straight weir. Crude, but useful for rough measurement. b) Construct a weir of 4"x4"x12'...

I suggest you check OSHA (USA) requirements! Phil Corso

Correction to my earlier post... The Thread No. is: 949513894 Regards, Phil Corso ([email protected])

See Control List Thread "Drum Level Control", Thread #959513894. Regards, Phil Corso ([email protected])

Shal1234, perhaps you don't have to use a "State of the Art Dynamic Braking System." Have you done a transient-stability study to determine the turbine-generator's acceleration-rate? Regards, Phil Corso ([email protected])

Regarding your first question, please clarify: 1) Presumably you have recorded the variations experienced by your local generation regarding their output "load", that is, MVA, MW, or MVAr. If so can you provide values? 2) Similarly, can you provide some idea as to the variation in bus...

Responding to MANIR's 13-Feb-09 (03:20) query about PS Class, CTs... I suggest you do a search of Control.com's archives. There are a number of topics covering the parameters you seek. Regards, Phil Corso ([email protected])

Philipe, I suggest you submit your post as a new topic... "induction generator." BTW, component substitution is one of the better ways to resolve problems. Regards, Phil Corso ([email protected])

Two reminders... 1) The typical R-L ciruit for an SOV is non-linear because the inductive component varies as the armature advances. 2) There is a substantial difference between DC and AC. Regards, Phil Corso ([email protected])

Responding to Sriram's 11-Feb-09 (08:00) query... the answer is yes! 1) If TR1 is the 2.0 MVA transformer, and TR1 the 1.5 MVA unit, then when paralleled, TR1 will carry about 56.5 percent of the combined load (2.6MVA), and TR2 about 43.5 percent. That is each will carry about 75 percent of...

Blackstoneboy, It's not a question of accuracy. First, I know of no syncronizing specification so sensitive that it can't meet a manufacturer's recommendations for voltage magnitude, phase deviation, and speed of closure. However, my point was to make you aware there are several areas...

Blackstoneboy... because the HV and LV winding connections of the power xfmr are both wye-connected then the phase-shift "seen" by the corresponding VT secondaries, is "essentially" small! I said "essentially" because there is some phase-shift. Its magnitude and angle are influenced by: 1)...

Responding to Blackstoneboy's 04-Feb-09 (03:33 query... What is intervining (utility) transformer's primary and secondary winding connecton arrangement? Regards, Phil Corso ([email protected])
