Prawo obliguje producentów i dystrybutorów energii elektrycznej do zapewniania odbiorcom ciągłej dostawy energii o możliwie najwyższejjakości. W środowisku regulowanych rynków niezawodność systemów dystrybucji energii jest niezwykle istotna, gdyż jakiekolwiek awarie systemu są bardzo kosztowne zarówno dla dystrybutorów i konsumentów.

Both natural and man-made drivers are spurring not only technological growth but are changing the nature of the electric grid. Concerns over global warming are only being compounded by the continuing billion dollar weather events. This is acting as a catalyst for the green reform and being realized in the growth of distributed generation (DG).

This is an easy solution to measure the impedance values for cables, the values are used for calculation of compensation factor in distance protection.The compensation factor is first theoretically calculated and these values can now be compared with the measured values.

 Self-powered relays will be animportant component for the protection of the smart grid.While they allow reducingthe cost of the protection system, they are definitely a challenge for relay test sets, that are required to provide the voltage and current signals to simulate the power system fault, but also the generatedsignals need to have necessary electric power to supply the protection relay.SVERKER 900 is designed to manage this task and this Technical Guide describes how two self-powered relays can be tested.This document guides through the testing of two self-powered overcurrent relaysfrom SEG GmbH (formerly Woodward), WIC-1 and WIP-1, with the relay test set SVERKER 900, for commissioning/maintenance purposes.The Technical Guide details on the principles adopted in the testing with reference to relevant IEC standards and to the relay manuals. In addition,basic instructions on the correct usage of the testing possibilities offered by SVERKER 900are described
