Protective Relays and RTAC Equipment

The City of Rocky Mount is requesting informal quotations for the purchase of microprocessor-based protective relays and a real-time automation controller (RTAC) for a substation upgrade. The total purchase is expected to be under $30,000. • The required equipment includes transformer protection relays, feeder protection relays, and a real-time automation controller. • The relays must provide various protection functions, such as overcurrent protection, voltage-based protection, and event reporting. • The RTAC must serve as a substation data concentrator and logic processor, with industrial-grade processor, minimum 8 GB RAM, and industrial-grade solid-state drive. • All devices must be fully compatible and capable of operating on the Owner's existing SEL-based communication architecture.
