NP   BC915

Bay control IED with IEC 61850 protocol

The optimal management of electrical power systems is based in particular on the reliability, availability and communication skills of protection, measurement and automation devices.
The NPBC915 bay control IED may be applied for various types of control applications. The NPBC915 comes with full current, voltage, power and energy measurement capability and may be equipped with additional I/O depending on application needs. Easy to use and powerful logic programming expands further the application range to more demanding control needs. Optional cards (I/O, communication...) can be inserted depending on application requirements. Large freely programmable HMI display provides quick visualization of the object, alarm and event status.
The NPBC915 communicates using various protocols including IEC 61850 substation communication standard.
