Back in April of this year the Newton-Evans Research Company reported on research concerning plans by domestic and international utilities to convert to full digital substations. The survey found that 34% of respondents from the U.S. and Canada expected to be implementing full digital substations by the end of 2018. Thirty-seven percent indicated they were not yet there. Also, larger utilities made up a greater percentage of the respondents indicating that they were not as far along. This is not too surprising since it is a major undertaking and a significant investment to go all digital. The good news is conversion can be performed incrementally as time and money allow. Furthermore, it makes sense to go incremental because each substation component converted and integrated into a digital communication system, increases functionality and provides other benefits such as continuous diagnostic capabilities and increased safety.
