Types of Instrument Transformers
A well-known Instrument Transformer Manufacturers in India and Pune, we are providing the best quality Instrument Transformer such as:
- Current Transformers (CTs): Current Transformers are designed to convert high currents into lower, measurable values that can be handled by meters and protection relays without compromising safety. Modern CTs increasingly incorporate digital sensing cores and fiber-optic communication to support advanced monitoring in smart grids. These upgraded Digital Instrument Transformers help power utilities achieve better fault detection accuracy and real-time data visibility.
- Potential Transformers (PTs): Potential Transformers reduce high system voltages to standardized and safer levels, enabling precise voltage measurement and monitoring in different electrical ecosystems. New-age PTs are equipped with enhanced insulation technologies and compact cores that deliver high accuracy even in fluctuating grid environments. These PTs are widely preferred for High Voltage Instrument Transformers and Medium Voltage Instrument Transformers applications where stability and precision remain essential.
- Combined Instrument Transformers: Combined Instrument Transformers integrate CT and PT functionalities into a single compact unit engineered for installations with limited space or high-density substation layouts. These advanced systems are used in modern digital substations where synchronized measurement and protection capabilities are critical. With IoT-ready communication modules and durable insulation designs, they support emerging smart grid and automation platforms.
