Current transformer cabinets are part of an electrical distribution system and house the current transformers which are used for metering purposes. Electrical enclosures are designed to prevent electrical shock to users by forming a physical barrier between the user and the live parts.Click to see full answer. Keeping this in consideration, what is the use of CT and PT?CT & PT are called the instrument transformer, because those are used to assist the measuring instruments for the measurement of electrical parameters like current, voltage, frequency, power factor, active power(MW), reactive power(MVAR) etc. of high voltage system.Also, what is 0.2 S Class CT? 0.2 and 0.2S refers to the accuracy of the Current Transformer. A 0.2S CT has a much higher accuracy than 0.2. Since, accuracy depends on the load of the system, IEC/AS[1] have developed different standards to define accuracy under different load conditions, known as “Accuracy Class” why do we use current transformer? Current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a standard ammeter.What is CT accuracy class?The accuracy class or simply class of measuring current transformer is 0.1, means the maximum permissible limit of error is 0.1%, more clearly, if we try to measure 100 A with a 0.1 class CT, the measured value may be either 100.1 or 99.9 A or anything in between these range.
