Best applications for medium voltage transformers—an overview
Medium voltage transformers play a critical role across vast industries. These transformers are utilized for applications requiring medium voltage to be stepped down to a lower voltage.
What is a medium voltage current transformer?
Medium voltage control transformers are designed and constructed to address industrial control application demands. Medium voltage is typically defined as containing a power supply rating anywhere from 5kV to 35kV. The transformers are engineered with a medium voltage primary winding and a secondary winding consisting of either a 120VAC, 60 Hz or 110VAC, 50 Hz.
Medium voltage current transformers must comply with the IEEE (Institute of Electrical and Electronics Engineers) and IEC (International Electrotechnical Commission) standards.
Dry-type transformers
Ventilated dry-type transformers are predominantly set apart by the fact that they utilize air rather than liquid as a coolant. Manufactured with proper ventilation, air flow prevents transformer components from overheating, which protects the transformer core as well as provides operative temperatures.
Leaks and spills are eliminated with dry-type transformers, which makes them an eco-friendly solution.
Oil-filled transformers
Oil-filled transformers are immersed in oil to control the temperature. The oil dissipates through the radiators attached on the transformer’s tank. These transformers require more maintenance compared to dry-type transformers.
Which applications are medium voltage control transformers used for?
Medium voltage transformers are commonly used for:
- The oil and gas industry
- Automation control
- Control power applications
How is the global medium voltage transformer market performing?
The global market is growing thanks to urbanization of developing countries resulting in an increased demand for electricity and the growth of the transmission and distribution network for the integration of renewable energy resources. In fact, the market is projected to grow at a CAGR of more than 2.5% from 2023-2028.
