Power Utilities – PT&D

The Worldwide demand for energy is on the rise due to population growth creating a critical need to transmit electricity to factories, commercial buildings, residential areas, and to the public infrastructures of expanding nations.

Power, transmission & distribution (PT&D) applications have real-time dependencies on data acquisition, protection, control and performance, which require a highly reliable and integrated communications network. Due to these dependencies, Ethernet has become the preferred communication network architecture for global PT&D applications, such as, Power Plants, Substations and entire SMART GRID systems. The flexible, integrated infrastructure of Ethernet communication networks make it faster and easier than ever before to achieve real-time monitoring and control of many different types of devices. In addition, benefits such as virtually limitless bandwidth capacity, immunity to electromagnetic interference (EMI), avoidance of ground loops, support for both short and long-haul communications, and increased security have led to increased demand for Ethernet fiber-optic networks.

Built to ease the migration to Ethernet, Transition Networks’ Industrial Ethernet products combine fiber-optic and wired Ethernet platforms, improving reliability and security and allowing for better visibility and control of data throughout your network. Designed and certified to operate reliably in harsh environments, Transition Networks’ Industrial Ethernet products are ideal for use in several power utilities applications.
