Answer / anoop pandey ji
HV voltages are in multiple of 11 only because they are
stepped-up by transformers having fixed voltage ratios.
these ratios cant be in decimals and are only in whole
numbers.
hence are in multiples in 11.

On load tap changer (OLTC) explode? Transformer Vector group: Ynd11 Rated Power: 353MVA Rated Current: 693A Voltage:294/20KV OLTC Type: T III Y1000 110/c 12193w Max Operation Current: 295A Step Voltage: 550V Arrangement in Tx windings: Y Connection Problem: Damage of Unit 1 Generator Transformer On Load Tap Changer (OLTC) Description of Incident: 9.00 a.m. :- Generator No Load test on excitation system started 10.30 a.m :- Carried out AVR change over test 11.30 a.m :- Preparation for Generator Manual Synchronizing test 12.00 a.m :- Manual Synshronizing test started. Observed incoming generator voltage higher than running voltage. CECR operator operated Generator Transformer OLTC to bring down the incoming generator voltage 12.03 a.m :-Generator Transformer abnormal alarm operated at Gen.Control Desk (CECR) CECR operater at Generator transformer bay informed that the transformer oil splashed out from OLTC. CECR operater informed that he heard explosion inside OLTC. Observed Oil level & Oil Flow alaram operated at Tranformer local annunciator. 12.05 am :- CECR operator 'Open Gen Field Breaker” 12.10 a.m. :- Elec1 team inspected the OLTC and found the OLTC rupture disk was broken and oil spilled at OLTC area. - Elec1 found the OLTC top cover bulging. Do anyone know why and possibility cause happen in this OLTC.
electricity requires a medium to flow and it cannot flow through air. so how does lightning come to earth through air without any medium?
i have some screw comprressor with 630kw power,i have established them with simple star to delta circuit,by the way there is so much inertia when the screw comprressors start, can you offer me contactors power with 400vac or any cataluge to choose the contactors
why only 11kv level is used for transmission purpose? why not 230v?
What is the power ratio between power in Star and Delta circuit?
