AQ E215 Energy Management Relay

AQ E215 energy mangement IED is developed for distribution automation smart grid applications. The AQ E215 provides a unique combination of  accurate power and energy measurement of class 0.2S and fault pass through indications and remote communication and control. This feature set makes AQ E215 perfect fit for secondary distribution monitoring and control applications. The AQ E215 may be equipped with additional I/O depending on application needs. The AQ E215 can be connected to conventional CTs and VTs or non-conventional low power current and voltage sensors. Easy to use and powerful logic programming expands further the application range to more demanding control, alarm and indication needs. Up to three optional I/O or communication cards can be inserted. Large freely programmable HMI display provides quick visualization of the object, alarm and event status. The AQ E215 communicates using various protocols including IEC 61850 substation communication standard.
