What is Alternator & Transformer? Common faults & protection in hinde

✓ What is Alternator ? An alternator is an electrical genarator that's convert mechanical energy to Electrical energy. ✓ What is Transformer? Transformer is electrical static device/ static machine which transform electrical power one circuit to another circuit by mutual induction. ✓ Common faulty in Alternator Prime mover failure Over speed Over Current Over Voltage Field failure Unbalance loading ✓ Common protection use in Alternator Differential protection scheme Balanced earth fault protection Stator inter – turn protection ✓ Common faulty in Transformer Open circuit Over heating Winding short circuits 1)Inter turn faulty 2)Phase to phase faulty 3)Earth faulty ✓ Protection relay used:- 1)Over Current relay 2)Buchholz’s relay 3)Earth faulty relay ✓ Protection against over voltage in Transformer:- Over voltages may be caused by conditions external or internal, to the system. @ Internal Cause:- 1) Sudden change in load 2) Insulation failure 3) Resonance 4) Switching operation of an unloaded time 5) Arcing grounds 6) Sudden operating of loaded line, particularly under short circuit condition @ External Causes:- Theses are mainly due to atmospheric condition, i. e, due to lighting. The device used for protection of electrical equipment from surge or over voltage are known as over voltage protection devices – 1) Ground wire 2) Earthing screen 3) Surge diverters or lighting arrester 4) Surge absorbers Get more videos subscribe My YouTube chanel 🔔 atoz knowledge 👀👀 My other videos 👀👀 Types of gear👇    • types of gear (spur, helical, herringbone,...   Sensor water tap.
