Digital substation
Smart and specialised test solutions for IEC 61850 networks
EnglishUK
Megger’s user-friendly IEC 61850 testing solutions ensure seamless interoperability, identify data inconsistencies and optimise protection, giving you confidence in your digital substations' standards compliance and performance.
In the digital substation, the analogue signals and proprietary one-to-one connections between IEDs and network sensors have evolved to data networks and data streams.
IEC 61850, with its abstract data models defined, can be mapped to several protocols: MMS (Manufacturing Message Specification), GOOSE (Generic Object-Oriented System Event), and SMV (Sampled Measured Values).
In digital substations, the conventional trip contacts are replaced by a GOOSE message and the conventional analogue voltages and currents are replaced by Sampled Values (SV) generated by Merging Units (MU).
GOOSE configuration can be a complex task. In MGC that configuration is optimised by ‘click-to-subscribe’ to map the appropriate GOOSE message to a binary input or output.
The briefcase-sized, powerful, single phase, SMRT1 relay tester is all you need for IEC 61850 protection testing, making it a cost-efficient solution to help you get started.
Easily detect differences between the design and the actual status of the GOOSE traffic by comparing it with its description in the SCD file. Smart grouping and highlighted differences also give a superb overview.
Connecting a PC to the substation network is not without its risks. However, the SMRT and FREJA units provide a secure access point to the substation network, and therefore cannot transmit ‘false’ data, nor infect the network with a virus. This is also known as the GOOSE ‘diode’.
The sniffer function ensure that nothing is transmitted and that all GOOSE traffic is captured and grouped for good overview. If a GOOSE change status is it highlighted so it is easy to detect changes.
With all IEC 61850 capabilities available from the on-board touch screen, there is no need for a PC. No PC connection issues, no software license issues, and no risk of transmitting viruses to the substation network.

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.
