Megger Line Impedance Kit for TRAX
The Line Impedance Kit is an accessory for the TRAX instrument. It consists of TSA230, a surge arrester box and TPB230, a protection box, plus cables and accessories.
The purpose of the line impedance measurement is to determine the line model?s parameters. In line model using symmetrical components these parameters are defined by zero sequence impedances Z1 and Z0, and they are used for calculation of the k-Factors.
Seven different test set-ups have to be measured. At each set-up, testing is done at two frequencies other than power frequency to allow power frequency interference to be effectively suppressed. The results will be shown at power frequency by interpolation of the measured points.
The performance of most distance protection relays depends on the positive sequence reactance X1 and the k factor. X1 is used to define the zone reach, which is crucial for the relay to decide in which zone a fault occurs
