Findings from Newton-Evans Study of Protective Relay Uses and Trends in the World’s Electric Power Utilities Depict a Receptive Market for Incorporating Advanced Technological Capabilities
Global Study Finds Continuing Growth in Protective Relay Market with Commitment to Increasing Protection Coordination and Grid Security Practices
Role of Synchrophasors and Teleprotection Continues to Grow…Providing Better Situational Awareness and Visualization to Help Prevent Outages
April 12, 2012 Ellicott City, Maryland. Newton-Evans Research Company has completed a five-month research study and survey of protective relay usage patterns in the world community of electric power utilities. Findings from more than 100 North American and international utilities, point to some new trends in adoption and use of protection and control techniques.
Among the key findings reported in the four volume study are these:
- The percentage of digital relays in the mix of all protective relays used by utilities continues to increase.
- The vast majority of new and retrofit units being purchased are also digital relays, but in some of the protection applications studied, such as motor protection and large generator applications, and in installations where electrical interference is strong, electromechanical and older solid state relays continue to have a niche market position.
- The annual world market for protective relays and related power systems protection devices continues to grow at a healthy pace.
- Manufacturers of utility systems protection equipment continue to expand their market coverage, with more than 20 firms each enjoying at least some share of the global market.
- Real-time analysis of synchrophasor data will become a major application for the emerging field of operational analytics.
- Communications protocol usage patterns continue to serve as a differentiator between the majority of large and mid-size North American utilities and their international counterparts.
The Newton-Evans survey of electric utilities included more than 20 detailed product functionality, related technical questions, and market-related issues, together incorporating more than 250 items of information from each of the participating utilities.
The 2012-2014 study is a series of four reports published this month. These reports are geared to the planning needs of protective relay suppliers, power industry consultants, and utility protection and control departments. These volumes include the North American Market Study, the International Market Study, Supplier Profiles, and Global Market Assessment and Outlook.
