The Substation Central Unit links all bay IEDs, centralizing substation data, running logic functions comprising multiple bays, and serving as the gateway to the SCADA system, and central or regional enterprise level applications.
The CPT can operate as a Substation Central Unit or as a RTU, solving the communications and data management of substation protection, control, and metering IEDs.
4CCY models allow cyclical interrogation of protection or control relays (from ZIV or other manufacturers) by a Control Unit (UCI or RTU), while simultaneously communicating with a Protection System or Protection Information Management Unit.
4CCN relays are transparent optical concentrators / diffusers, designed to organize communications networks, at substation level, between protection and control relays and relays or concentrators at a higher level.
