Current Transformers in Power Protection System– A Protection Current Transformer is used to reduce the currents in power systems thereby protecting it from faults. These Current Transformers measure the actual current in the primary side and produce proportionate currents in their secondary windings which are completely isolated from the primary circuit.

Current transformers (CTs) are sensors that measure alternating current (AC). Like any other transformer, a current transformer has a primary winding, a magnetic core, and a secondary winding (the primary winding of the current transformer is the wire carrying the current you want to measure). Current Transformer. Current transformers (CT) are broadly employed in order to measure high magnitude currents. Such transformers basically step down (lower) the current which is to be measured, so that it can be measured with an average range ammeter.

Current transformer

Current transformers, along with voltage or potential transformers are Instrument transformer. Current transformers are designed to provide a scaled-down replica of the current in the HV line and isolate the measuring instruments, meters, relays, etc., from the high voltage Oil-insulated current transformer are used to convert high transmission line currents (up to 5000 A) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system.

Manufacturer’s name or trademark 2. Traditionally, current transformers have been designed with a standard secondary current of 5 Amps which is used with conventional analog instruments and meters. Many control designs still utilize this standard concept which in many cases necessitates a mechanically larger unit than needed when hooked up to an op-amp or similar electronic circuits.

Errors in Current Transformer. The errors that occurred in this transformer include the following. The primary winding of this transformer requires MMF (magnetomotive force) to generate flux which draws magnetizing current. The transformer’s no-load current includes an element of core loss component and occurs hysteresis and eddy current losses.

2011-04-16 · Current transformers Principle of operation of CT. A current transformer is defined as “as an instrument transformer in which the secondary current is substantially proportional to the primary current (under normal conditions of operation) and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.”

Like any other transformer, a current transformer has a primary winding, a magnetic core, and a secondary winding (the primary winding of the current transformer is the wire carrying the current you want to measure). The current transformer (CT) is a type of instrument transformer designed to measure high-value current in the power system. The primary has few numbers of the turn of heavy wire, and the secondary of the current transformer has many turns of fine wire. Current Transformers … Current Transformers occupy a vital part in the measurement and protection scheme of any electric installation. Hence, it is imperative that the choice of CT is made with full knowledge of the application and the number of relays and meters which are to be connected to it. Current Transformers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Current Transformers.
