Introduction – Travelling waves on transmission lines – Wave Equation – surge impedance and
wave velocity – Specification of Travelling waves - Reflection and Refraction of waves – Typical
cases of line terminations – Equivalent circuit for Travelling wave studies – Forked line –
Reactive termination – Analysis of trapezoidal wave - Analysis of complicated waves.

system – Self and mutual surge impedance – Voltage and currents for two conductor
systems.
UNIT III LIGHTNING, SWITCHING AND TEMPORARY OVERVOLTAGES 9
Lightning: Physical phenomena of lightning – Interaction between lightning and power
system – Factors contributing to line design – Switching: Short line or kilometric fault –
Energizing transients - closing and re-closing of lines - line dropping, load rejection -
Voltage induced by fault – Very Fast Transient Overvoltage (VFTO)
UNIT IV PROTECTION OF SYSTEMS AGAINST SURGES 9
Transmission line insulation and performance – Ground wires – Protective angle – Tower
footing resistance – Driven rods – Counterpoise – Protector tube – Substation protection –
surge diverters – Selection of arrester rating – Location of arresters – Influence of additional
lines – Effect of short length of cable – Surge capacitor, surge reactor and surge absorber –
Shielding substation with ground wires – Protection of rotating machines.
UNIT V INSULATION CO-ORDINATION 9
Principle of insulation co-ordination in Air Insulated substation (AIS) and Gas Insulated
Substation (GIS), insulation level, statistical approach, co-ordination between insulation and
protection level –overvoltage protective devices – lightning arresters, substation earthing.
