DER are connected into medium voltage levels in the network and the protection is rather basic. Self-powered relays are common which create unique test challenges. All together require a cost efficient but capable solution.
The Megger MRCT is a light weight, robust, portable unit used toperform demagnetization, ratio, saturation, winding resistance, polarity, phasedeviation, and insulation tests on current transformers. The MRCT automaticallycalculates ratio errors, saturation curves, and knee points. The MRCT providesa microprocessor-controlled variable voltage and current output and precisioninstrumentation for automatically testing single and multi ratio CTs, reducingtesting time and increasing productivity. The MRCT will directly connect tomulti ratio CT’s and perform all tests – saturation, ratio and polarity,winding resistance and insulation – on all taps with the push of a button andwithout changing leads.
In all parts of the network, there are a few fundamental protection schemes which are used to protect the network, i.e., overcurrent and overvoltage.

IEC 61850 require specialized solutions to effectively verify that the digital substation is properly configurated. GOOSE and Sampled Values are closely related to protection testing.

In large-scale generation stations, there are many aspects to consider when it comes to both protecting the assets and to ensuring a stable network, making the protection schemes rather complex.

The power transformer is the most valuable asset in the substation and therefore rigorous protections schemes have been developed to both protect it but also to keep the network up and running.
