50 Hz / 60 Hz Phase Shifting Transformer

Phase Shifting Transformer – Reliable Solution for Power Flow Control

A Phase Shifting Transformer (PST) is a highly specialized type of power transformer designed to control the power flow in electrical transmission networks. Unlike conventional transformers, which only step up or step down voltage, a phase shifting transformer introduces a controlled phase angle difference between the input and output voltages. This unique capability allows it to regulate active power flow, improve network stability, and prevent overload in parallel transmission lines.

Key Role in Power Transmission

In modern power grids, especially in interconnected networks, uneven load sharing between parallel lines is a common problem. A Phase Shifting Transformer helps solve this issue by altering the phase angle of the voltage, which directly controls the power flow through different paths. This makes it an essential device for utilities, industries, and power distribution companies where stable and efficient electricity supply is critical.

Technical Excellence

Our Phase Shifting Transformers are designed with advanced engineering to meet the highest industry standards (IS/IEC/ISO). They are available in a wide range of ratings, from 500 kVA up to 20 MVA, and can be customized for specific voltage levels such as 11 kV, 33 kV, or higher. Both oil-cooled and dry-type models are available, depending on the installation environment and customer preference.

The transformers are built with premium-grade copper/aluminum windings, robust insulation systems (Class B, F, or H), and high-efficiency designs achieving up to 98% performance levels. This ensures long service life, reduced energy losses, and reliable performance under continuous load conditions.

Benefits of Using Phase Shifting Transformers

• Improved Grid Stability: Balances load between parallel lines and prevents system disturbances.

• Controlled Power Flow: Allows utilities to redirect power as per demand, ensuring optimal utilization of network capacity.

• Reduction of Loop Flows: Eliminates unwanted circulating currents in meshed networks.

• Customizable Design: Tailored to meet specific requirements of industrial and utility customers.

• Durability and Safety: Manufactured with robust enclosures, high-quality insulation, and protective systems for safe long-term operation.
