GE General Electric Technical Specifications: IS200TRPSH1A

The relay calculates the distance to fault with fault resistance compensation. For the fault location feature, a

IS200TRPSH1A fault is defined as an event that has caused a current level greater than the pickup threshold of an overcurrent

protection feature programmed to Trip or Trip & AR (760 Only), which has remained for sufficient time to cause

the relay to produce a Trip command. After this has happened, the apparent distance to the fault is calculated

in a background mode, IS200TRPSH1A maintaining all other features in operation. The distance calculation is based on the

assumptions that:

(a) the feeder positive and zero sequence impedances are a constant per unit distance, and

(b) mutual compensation is not required.

If the feeder utilizes conductors of different sizes, or more than one physical arrangement of conductors

The IS200TRPSH1A algorithm uses prefault system data to reduce the error caused by variable fault resistance, so inaccuracy

is introduced for a fault which occurs when no load current was present. Also, error is introduced if the feeder

has sources at locations other than the location of the relay, due to infeed effects.

The algorithm contains three sets of equations that are used to perform the calculations for a specific fault

type: phase to ground, phase to phase to ground, phase to phase, and three phase. Each of the sets (other

than three-phase) consists of a subset which covers all combinations of phases. The algorithm therefore uses

a fault identification procedure to select the appropriate equations to be used for calculation. This procedure

uses both prefault and fault current phasors from memory to identify the type of fault. The prefault data is taken

from a sample collected three power frequency cycles before the pickup of the overcurrent element to ensure

the IS200TRPSH1A sample contains only load current. The after fault data is taken from samples collected 1.5 power frequency

cycles after overcurrent pickup to ensure the current had existed for at least one complete sampling interval.

As well as the apparent distance to the fault, the locator records the feeder apparent reactance (with fault

resistance removed if prefault current was available.) This parameter can be very useful in estimating the loca

tion of a fault on a feeder tap, where the apparent distance can be calculated as beyond the feeder end. The

date, time, type of fault, and phases involved are also stored for the event. Non-volatile memory is provided for

the past ten events, in a FIFO queue, available under ACTUAL VALUES \ A1 STATUS \ FAULT LOCATIONS.

If the feeder has a source with a grounded neutral, and is therefore capable of providing

ground fault current, the bus VTs must be both connected and selected as Wye in setpoint S2

SYSTEM SETUP \ BUS VT SENSING \ VT CONNECTION TYPE, to allow the fault locator to perform the cal

culations properly. If the fault classification results in a phase to ground fault, the program

checks that the setpoint noted above is set to ‘Wye’ before the calculation is permitted.
