Answer / ankit sinha

when a part of primary winding of a transformer is short
cktd the v1 reduced,so the v2 will also be reduced by the
same factor.this will be cleared by the relation-
v1/v2=n1/n2
since n1 and n2 are remain same,v2 should be reduced
inorder to maintain the ratio same.

Answer / abhishek singh

IN XMER WE KNOW THAT V2/V1=N2/N1.SO WHEN PRIMARY PART OF
XMER IS SHORTED THEN THERE IS NO INDUSED EMF IS PRODUSED IN
IT MEANS E1 AND DU TO THIS NO ANY FLUX IS PRODUSED.SO XMER
DOES NOT ABLE TO TRANSFORM ELECTRRICAL ENERGY TO ANOTHER
CKT .SO IT DOES NOT WORK FOR WHICH IT IS USED.

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.
