Testing self-powered relays with SVERKER900
 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

Remote Time Sync - MPQ
The MPQ software can be configured to automatically sync the remote MPQ to the network time periodically. This saves the expense of a GPS and removes the possibility of losing the GPS signal.

Comtrade export - MPQ
A Comtrade Export feature is valuable when analyzing protection devices. It can help determine why a protection device is tripping or it can help determine if the protection device will trip under particular real world conditions.The MPQ analyzer can be left in the field for months or years at a time. During this time,it will record multiple real world events. These events can then be exported as a Comtrade file and then can be played back to protection devices tosee how they react.

Delta measurement with an MPQ1000
The power measurement for a delta configuration uses a 2 wattmeter method even thoughthereare 3 phases.When measuring a wye all the voltages are referenced to neutral, referred to as line voltages. The measured currents are also line currents. Since both the voltage and currents are line values,the measurement does not introduce any phase shift.
