EasiLinc Protection Modules

The EasiLinc product line makes protective relay application simple. By combining application and integration techniques refined by years of experience with the simple and powerful EasiLinc Setting Transfer Software, POWER Engineers makes today's high performance protective relays easier to use than the discrete relays and other system components they replace. 

EasiLinc protection modules include:

  • Protective relay and test switches, mounted and pre-wired in a 19" panel
  • Supporting schematics, provided in several electronic formats to document the relay connections to the system
  • Application setting files to define the logic, event reporting, load profiling, integration, etc. needed to provide full relay functionality.

You need to determine and implement only thirty simple protection settings to complete the configuration prior to installation. 

Used together, the modules, documentation, and setting transfer software will reduce, by as much as 90%, the engineering and technician time required to apply and install high-performance protection.

Use EasiLinc modules to:

  • Replace out-of-date, maintenance intensive, or obsolete protective relays.
  • Economically expand existing substation or plant facilities.
  • Protect and/or integrate new equipment quickly, with reduced cost and resources.

EasiLinc ELOCS Overcurrent Protection and Control Module

The ELOCS module offers feeder overcurrent protection, reclosing, and front-panel controls. This module is based on the popular SEL-351S Relay, but is much simpler to implement and use. Fewer than 30 settings are needed to place the ELOCS package in service.

EasiLinc ELOCA Overcurrent Protection Module

The ELOCA module provides high-performance feeder protection without the front-panel operator interface. This module includes an SEL-351A Relay and test switches, pre-wired, and mounted in a sub-panel suitable for a 19 rack or switchgear cutout mounting. Consider this package for budget-sensitive applications, or when you plan to include an EasiLinc HMI.

EasiLinc ELGEN Generator Protection Module

The ELGEN module offers a full suite of generator protection functions, including models having differential and synch-check functions. Based on the popular SEL-300G Relay, the ELGEN protection module simplifies setting development for generator protection applications and shortens installation outages. 

EasiLinc ELXFR Transformer Protection Module

Four EasiLinc models are available for a variety of distribution, transmission, and power plant transformer protection applications. The ELXFR, ELXFE, and ELXFA EasiLinc modules are based on variations of the SEL-387 Differential Relay. The ELXF5 protection module includes an SEL-587 and an SEL-501 Relay, offering primary differential and backup overcurrent protection in one package for two-winding transformers. The transformer protection modules are not yet supported by the EasiLinc Setting Transfer Software, but we are working to make that support available soon.

EasiLinc ELTLL Transmission Line Current Differential Protection Module

The ELTLL module offers transmission line current differential protection, zone distance protection, directional overcurrent protection, communication-aided tripping schemes, reclosing and sync check functions. Based on the SEL-311L Relay, ELTLL is much simpler to implement and use. Simplify design, installation and settings with the EasiLinc ELTLL Transmission Line Current Differential protection module.

EasiLinc ELTLC Transmission Protection Module

The ELTLC module offers transmission line zone distance protection, directional overcurrent protection, communication-aided tripping schemes, reclosing and sync check functions. This module is based on the popular SEL-311C Relay, but is much simpler to implement and use. Use the ELTLC for all your zone distance transmission line applications.
