Power Utilities

Our Role in Power Utility

We have over 25 years of experience providing reliable communications products for power, water and gas utilities. Using time-tested applications we help preserve legacy devices and connect utilities to a modern network. Integrate serial, C37.94, 4-wire analog for SCADA, Teleprotection, and analog radio over a T1, E1, IP, or Ethernet network.

Specializations and Applications

Teleprotection over IP, MPLS and T1 Networks

Designed for critical and low latency applications, these Teleprotection solutions exceed low latency, dependability and security requirements. Products pass a variety of tests from uncongested QoS to backbone congestion with Latency Mode 3. Supported interfaces include C37.94, serial RS-232, and G.703.

SCADA Applications

Supervisory control and data acquisition (SCADA) is essential to support real-time communications. Utilizing a modern IP platform the JumboSwitch® offers a complete solution to monitor network applications and identify abnormal conditions. Since the beginning, TC has been testing and implementing SCADA technology for power utilities. Customers can trust that networks will be a cinch to monitor.

Legacy Network Modernization

Expiring or expensive 4-wire Analog and T1 leased lines are nudging utility companies to consider alternatives. It’s possible to use existing fiber and microwave IP/MPLS networks to connect Analog and T1/E1 equipment. TC products provide comprehensive support for existing legacy networks as well as gradual shifts to Ethernet/IP. Legacy devices and JumboSwitch® products offer flexible connectivity options. This includes the latest in Ethernet-over-PDH technology including Ethernet over T1/E1, Ethernet over T3/E3 and Ethernet over OC-3/STM-1. More information about leased line replacement.

A History of Helping
Customers Succeed

Since the beginning, TC has focused on bridging legacy service with IP/Ethernet and enabling communication between devices. In the founding years TC worked alongside the Department of Water Resources. Together they brought fiber connectivity to SCADA applications. Since then plans have expanded to many critical utility applications including Teleprotection and substation communications.
