Oden System Configuration
Depending on the ODEN configuration, different max current/voltages output levels are possible. In total there are 46 ODEN combinations. This application note focuses on two different application examples of an ODEN setup. Test of Current Transformers and Low Voltage Breakers.

Check of impedance with ODEN or INGVAR
Estimating a load is important when setting up a system to test for example a low voltage breaker or anything else that may require a high current and high comply voltage. This application note guides you through how to determine the total load and from there determine an appropriate system configuration for the ODEN or INGVAR system.

Electrical Tester - November 2022
Read our fourth issue of ET Magazine! This issue is filled to the brim with informative and educational articles, including our feature article highlighting how DC power has become an integral factor in our evolving relationship with electricity, and how it’s helping us realise the next steps in our complex and ongoing journey with electrification.Additionally in this issue, we look into aspects of IEC 61850, give you a global view of power transformer technology, and give you advice for recruiting engineers in the power system protection community. But that’s not all as this issue has over 20 articles in it, spanning a huge range of industry topics. Highlights include an article looking at reindeer and sustainability, an article looking at how a local community managed to preserve Tesla’s last remaining lab, and an article looking at stray currents in water pipes in a reverse osmosis plant.As always, we have our Geek Challenge to test your knowledge as well as some great reading suggestions from our Book Club and some industry news to keep you informed.

Riktat Jordfelsskydd - SVERKER 900
Felströmmen är satt till 80mA för att simulera den höga strömmen som skapas vid ett intermittent jordfel. Nollpunkt spänningen är satt till 20V, konfigurering görs i 13 steg. Fel stegen och dom två första minnes stegen sätts på 20ms. Dom övriga minnes stegens tider ställs in för att komma så nära inställd tidsfördröjning som möjligt.I generator konfigurering ställ U4gen på hjälpspänning DC.

MOM2 and CT in loop
For most of the breakers the MOM/DLRO is as accurate as other types of micro-ohmmeters but if there is a current transformer (CT) in series with the breaker contact to be tested then it is advisable to make some basic checks
