or grounded objects; it occurs when a conductor
breaks and falls on a non-conducting surface such
as asphalt road, sand, cement, grass or perhaps a
tree limb, producing very little if any measurable
current. The arcing that often results from HIFs can
have deadly fire and electrocution consequences. A
HIF may result in damage to the electrical system,
loss of power to customers, public hazard, or
possible unsafe conditions due to arcing and
flashing and possible property fire.
This paper explains high impedance fault
characteristics and modeling of this fault in
MATLAB Simulink software using variable
resistor, also clearance method of these fault types
are discussed
