Substation Equipment

Ringtech design, Installation & Commissioning Service

Ringtech provides design, Installation, testing and commissioning services to vendor. Ringtech will dedicate Installation team & Commissioning Engineer to test, and install Substation Equipment, SCADA, Meter, Motor etc. components and systems. Our Commissioning Engineers understand the big picture and are capable of commissioning Greenfield projects as well as challenging retrofits being cut into live stations.

Their knowledge of transmission, distribution, and generation systems enables them to develop and execute plans that work under the customer’s tight outage schedules and requirements. Some of the Commissioning Engineer’s responsibilities are to review the design drawings, develop and execute test plans provide technical and perform final in-service checks when bringing the equipment online for the first time.

High Voltage Substation Design, Equipment Installation & commissioning Service

Transmission and distribution systems, upgrading substation infrastructure and capacity is essential to keeping the lights on in the communities you serve. Whether you are taking on a rebuild, an expansion or a Greenfield project, Ringtech’ s power engineers and designers guide you through all phases of development, from planning through commissioning.

We implement solutions from initial concept, land acquisition; permitting and complete civil, structural, and electrical design to deliver completed integrated/automated substations, switching stations and switchyards.
