Measuring cable impedance with SVERKER900
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.

Preventive maintenance of rolling stock
The test and maintenance of electrical components on rolling stock is not an easy job to do. Some maintainers dismount some of the parts and bring them to a central location for revision and maintenance. This is a cumbersome and time consuming exercise. In many cases, the electrical parts are replaced only when they break down and are not subject to periodical testing. This of course holds a risk as some parts, e.g. circuit breakers, are crucial for safety reasons.

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.

AUTO data analysis with the MPQ
The Metrosoft PQ software has a powerful data analysis feature. This feature allows you to automatically analyze the recorded data and see what parameters are out of requirements.To use this feature the nominal recorded voltage and frequency needed to be entered. However these values can change from recording to recording.A new AUTO option has been added to the data analysis screen.
