Directional earth-fault protection - SVERKER 900
The fault current is set to 80mA tosimulatethe high current generated at the intermittent earth fault. The zero voltage is set to 20V;theconfiguration ismade in13 states.The fault states and the first two memory states are set to 20ms. The memory states havetimesselected togetthetrip as close to set time 1,2s as possible. In generator configuration,set U4gen to aux voltage DC.Set “Advanced mode” in SVERKER configuration.

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.

DLRO2: long test lead test mode
When measuring very low resistance the four-wire test method has for many years been the standard method. The main advantage being that it simply and easily removes the resistance of the test leads from the measurement. However, what happens when those test leads need to be verylong?

DLRO2: new difference meter
Introducing the first low resistance ohmmeter to feature a difference meter, a device that turns changes in resistance into a moving pointer and percentage change. When testing multiple similar connections, it makes it easy to spot those small increases in resistance that eventually turn into major faults.
