Engineering Services. How do you know if your fuses and or circuit breakers will work safely when called upon to interrupt a serious electrical fault or short-circuit? The answer is, most people do not know for sure. The issue is if the available electrical current exceeds the capability of the protective devices in the electrical distribution system, an electrical fault can cause these devices to virtually disintegrate. This determines if a device can interrupt current available at the time of a fault. Often, the source side of the interrupting device is an electrical bus in a piece of switchgear. Forces are created when current flows through bus bars and varies depdendent on phase location.

During a fault, current magnitude is radically greater than normal current flow, and the force between the bus bars is increased by the square of current increase 16x the normal force if the fault current is 4x normal. A Coordination Study looks at protective devices from a slightly different angle to. Back flashover occurs in transmission lines during lightning, when the potential of the tower rises with respect to the conductor. This causes voltage across the insulator to rise beyond the limits resulting in a flashover. The severity of the overvoltage waves depends upon the magnitude and the steepness of the lightning stroke current. Switching overvoltages SOV are generated when a circuit is energized, reenergized or opened by a GIS circuit breaker and disconnector switch operations.

But it is easily limited by re-strike free operation of GIS circuit breakers and shunt reactors. A satisfactory protection against switching surges will normally be obtained if the GIS are well protected against lightning overvoltages. Temporary overvoltages TOV can originate from faults, switching operations such as load rejection, resonance conditions, and nonlinearities or by a combination of these.
