7 reasons to choose Eaton's E-Series relays


Harness the flexibility of integrated IEC 61850 with GOOSE messaging

Protective relays that utilize a manufacturer’s proprietary protocol can pose significant challenges for utilities, including difficulty changing a control scheme due to a limited selection of components. Even more, relying on one manufacturer leaves a utility company vulnerable to the risks of single sourcing, including potentially long lead times.

61850 Edition 2 with GOOSE messaging

Because Eaton’s E-Series family of medium-voltage protective relays supports 61850 Edition 2 with GOOSE messaging, utilities gain exceptionally fast, real-time control and monitoring of power system devices, as well as the ability to seamlessly connect devices together through the open protocol. 

E-Series medium voltage protective relays featuring IEC 61850 with GOOSE messaging enable equipment and control scheme modifications to be completed remotely, without requiring a field service technician to be dispatched to the site.

We understand your emphasis on safety first ― and it’s our top priority, too.

Eaton recognizes that nothing is more importance than ensuring the safety of utility personnel. The E-Series is designed to do just that ― helping to shield workers from high-voltage transformers by enabling remote access of equipment through IEC 61850 with GOOSE messaging.

Utilities can diagnose issues, add or change equipment, and support interaction between components ― all without having to physically dispatch a technician in the field. From repairing a tripped breaker to shutting off a device, changes can be completed using standard computer settings. 

Even more, utilities that standardize on IEC 61850 with GOOSE messaging can eliminate up to 75% of copper wiring for control circuits. Although control wiring has historically been 110V AC, when leveraging the speed and flexibility of IEC 61850 with GOOSE messaging, control wiring voltage is reduced to communication cable levels ― significantly enhancing personnel safety.


The E-Series makes programming a breeze.

With thousands of settings inside of a relay, any means of simplification helps to ease operation for utility personnel. Not only are E-Series medium-voltage protective relays incredibly simple to program, they provide additional ease of use thanks to embedded software that features an intuitive user interface and innovative Device Planning capability. By enabling you to turn off functions you aren’t using, Device Planning simplifies the relay’s feature tree and programming, so users navigate only through the features they need. 

The hardware and software commonality across the E-Series family platform makes it seamless for users to program simple to complex settings or schemes for each of their unique applications, while an intuitive user interface affords flexible configurations and simple alarming and notifications.
