In 2016, Newton-Evans Research Company conducted a six-month research study of protective relay usage patterns in the world community of electric power utilities. Findings from 114 large and mid-size utilities in 28 countries pointed to some newer trends in adoption and use of protection and control technology.
Importance of Purchasing “Known” Relays: Sixty-five percent of the North American respondents strongly agreed with the statement, “It is important that we purchase known relays (a proven product with which we have had prior experience).” Overall, 97% of North American respondents strongly agreed (65%) or agreed (32%). Three people were neutral about this statement. None of the respondents expressed any level of disagreement. Eighty-two percent of North American utilities serving more than 500,000 electricity end users strongly agreed with this statement.
Fifty-three percent of international respondents strongly agreed with this statement. Forty-one percent agreed only somewhat. One person disagreed and one person was neutral about this statement.
The role of “purchasing known relays” makes it very difficult for new market entrants to gain a share of this multi-billion-dollar global protective relay market. Similarly, it has become equally difficult for existing relay suppliers to gain new customers unless the relays are components of larger electrical equipment (motors, transformers, switchgear, etc). Despite these market constraints, caused in large part by a steep learning curve in programming and protection settings, some relay manufacturers have increased their market presence through specialization in the design and supply of protective relays for one or more product segments (protection of motors, transformers, generators, switchgear and the like). Other manufacturers have continued to offer a wide range of protection solutions, but address specific world regions or specific types of electric utilities or industries.
