Innovated protective functions
The protection of generators over the past fifty years has evolved from discrete or single function electromechanical relays to static (electronic) single function protection relays and finally to multifunctional digital protection systems. Beckwith Electric began developing and manufacturing protection solutions during the static protection era. Through cooperative efforts with the Gas Research Institute, Beckwith developed the multifunctional digital relay. Beckwith's Pride Relays used for interconnection of distributed generation contained functions used to protect generators and launched Beckwith into the generator protection industry. The industry's application of multifunction generator protection relays, combined with recent developments in providing more sophisticated and innovative protection functions required for utility-sized generators, has lead Beckwith to the forefront of modern generator protection systems.

Digital Relay Features
Commissioning multifunction digital relays and motor bus transfer controls offers some unique challenges to the user. Multifunction relays have protective functions that interact with each other, making testing more complicated. They can also be programmed to do control logic, which must be verified. In addition, digital relays can have multiple setting groups that may be switched to address varying system conditions. This flexibility increases the commissioning complexity. Beckwith relays have significant input monitoring capability and integral graphic commissioning tools that greatly assist the user in determining whether these relays are set properly and are properly connected to their CT and VT inputs. This reduces commissioning time and helps to verify that the relay is functioning properly.
