TRANSFORMERS

UPR’s fleet of transformers are available at its various regional depots to support its power fleet. These transformers can be configured for step up/step down purpose, depending on the actual site power demand. UPR also possesses auto transformers, both dry and mineral oil types.

For the more complex requirements whereby higher voltages may be called for in the project, UPR has transformers with 3.3kV, 6.6kV, 13.2kV, 13.8kV, 20kV and 22kV design. They are available with an individual capacity of 2.0MVA, 3.15MVA and 5MVA. They can be paralleled to provide more than 80MVA of capacity.

Uniqueness of UPR Transformers:

• Compact in size with high capacity.
• ABB and other well-known brands are used to reduce losses caused by high impedance
• Optional for housing in enclosure with lifting corners and forklift pockets.
• For larger units, they are assembled as containerised unit, completed with cooling fans and switchgears to provide adequate safety measures.
• Temperature and pressure protection.

Switchgear System

UPR utilises world renowned brand of switchgears such as ABB and Schneider for high voltage switching and protection. These switchgears are compact in size and designed for up to 25kA, 3 seconds fault protection.

The switchgears are usually housed in a well-ventilated environment with IP54 insulation. Depending on the project needs, synchro-check meter, power metering, live-on indication lights, main breakers and other safety devices can be found in the switchgears.
