Low Voltage Current transformers may be either Tape Wound or Epoxy Resin Cast. They may be either Ring Type or Wound Primary Type. For lower ratio, high accuracy CTs, Wound Primary Construction is preferred. For higher ratio CTs, Ring Type Construction is preferred from the economical point of view. Ring Type CTs are most economical if the primary current is 200 A or more. For primary currents lower than 200 A, Wound primary CTs are most economical. Low Voltage (LV) or Low Tension (LT) Current Transformers are one and the same thing. These type of transformers are usually insulated with Epoxy Resin or Cotton Tape and are primarily used in electrical systems for metering and protection. The standard secondary output from such transformers are 1 Ampere or 5 Amperes.
Tape wound current transformers are widely used in switch gears, distribution systems, electrical generators, indoor or outdoor control panels and control instruments.
Macroplast manufactures Low Voltage Current Transformers of 1, 0.5, 0.2, 0.2s accuracy class. Our LT-CTs are constructed with only a single secondary winding. We possess the expertise to manufacture these either in tape wound or resin cast type depending on client specifications and requirements.
Servo Transformer is precisely designed and developed by us for consistent monitoring of the output voltage and controlling the variations of the input voltage. Our heavy duty Servo Transformer is well appreciated by our customers for its optimum voltage regulation. It has a robust construction, long functional life and requires low maintenance. Customers can avail them at industry leading prices.
