Reliable, Repeatable Measurement
In today’s electrical infrastructure, accurate current measurement and reliable protection systems are essential for maintaining operational safety and efficiency. Low Tension Current Transformers (LT CT) play a crucial role in low-voltage electrical systems by providing precise current measurement, dependable metering, and effective circuit protection.
At Varsha Engineers, we manufacture high-performance LT Current Transformers engineered for precision, durability, and long-term reliability. Designed for seamless integration into LT panels, our LT CTs ensure accurate energy monitoring, enhanced safety, and stable performance in industrial, commercial, and utility applications.
Our Low Tension Current Transformers are available in wound primary and window type constructions and can be manufactured using resin cast, tape insulated, or varnish impregnated designs according to customer-specific requirements.
Built with advanced engineering technology and premium-quality materials, our LT CT solutions deliver reliable and repeatable measurement for modern electrical systems.
A Low Tension Current Transformer (LT CT) is an electrical device used for measuring alternating current in low-voltage systems. It converts high current values into smaller, safer measurable values suitable for meters, relays, and monitoring equipment.
LT Current Transformers are commonly installed in LT electrical panels, switchboards, control systems, and distribution panels for current monitoring, energy metering, and protection applications.
These transformers improve operational safety by isolating measuring instruments from high current circuits while maintaining accurate current readings.
The working principle of an LT Current Transformer is based on electromagnetic induction.
When alternating current flows through the primary conductor, it creates a magnetic field inside the transformer core. This magnetic field induces a proportional current in the secondary winding, which is connected to metering or protection devices.
The transformer reduces high current values into standardized lower current outputs, allowing safe and accurate measurement without directly connecting instruments to high-current circuits.
This process ensures:
In wound primary CTs, the primary winding is physically wound around the transformer core. These are commonly used where precise current transformation ratios are required.
Window type CTs have an opening through which the conductor or busbar passes directly.
Resin cast LT CTs provide strong insulation and excellent environmental protection.
These transformers use insulation tape for electrical insulation and protection.
These CTs are treated with insulating varnish to improve durability and insulation properties.
The core transfers magnetic flux and improves transformer efficiency.
Carries the input current to be measured.
Provides reduced output current for measurement and protection devices.
