OBJECTIVES:

 To educate the causes of abnormal operating conditions (faults, lightning and switching surges) of
the apparatus and system.
 To introduce the characteristics and functions of relays and protection schemes.  To impart knowledge on apparatus protection
 To introduce static and numerical relays
 To impart knowledge on functioning of circuit breakers

UNIT I PROTECTION SCHEMES 

Principles and need for protective schemes – nature and causes of faults – types of faults – fault
current calculation using symmetrical components – Methods of Neutral grounding – Zones of
protection and essential qualities of protection – Protection schemes

UNIT II ELECTROMAGNETIC RELAYS 

Operating principles of relays – the Universal relay – Torque equation – R-X diagram – Electromagnetic Relays – Overcurrent, Directional, Distance, Differential, Negative sequence and
Under frequency relays.

UNIT III APPARATUS PROTECTION 

Current transformers and Potential transformers and their applications in protection schemes – Protection of transformer, generator, motor, busbars and transmission line.

UNIT IV STATIC RELAYS AND NUMERICAL PROTECTION 

Static relays – Phase, Amplitude Comparators – Synthesis of various relays using Static comparators – Block diagram of Numerical relays – Overcurrent protection, transformer differential protection,
distant protection of transmission lines.

UNIT V CIRCUIT BREAKERS 

Physics of arcing phenomenon and arc interruption – DC and AC circuit breaking – re-striking voltageand recovery voltage – rate of rise of recovery voltage – resistance switching – current chopping -interruption of capacitive current – Types of circuit breakers – air blast, air break, oil, SF6 and vacuumcircuit breakers – comparison of different circuit breakers – Rating and selection of Circuit breakers.

TOTAL : 45 PERIODS

OUTCOMES:
