The focus here is on the IEC 61850 standard, which describes a special protocol for protection and control technology. The requirements for the hardware itself include an extended temperature range (+80C°), conformal coating (coating of the printed circuit board) and a specially sealed housing. 

The transmission of the data is realised by means of fibre optic cables, which makes the signals insensitive to EMC influences. 

Spectra offers a portfolio of switches that meet the high requirements in this special area of application.
