Current transformers convert almost any amount of primary current into “bite-sized” secondary currents. there are two main standards to which current transformers are designed. This alternating current is proportional to the current in its primary. for measuring, metering and/or protective purposes. Newark offers fast quotes, same day shipping, fast delivery, wide inventory, datasheets & technical support.

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.” Once the current has been reduced it can be safely monitored and measured using an ammeter.Current transformers can perform circuit control and perform roles for safety protection and current limiting.Our website uses cookies and similar technologies to provide you with a better service while searching or placing an order, for analytical purposes and to personalise our advertising to you. Current Transformers, Inductive Voltage Transformers, Capacitive Voltage Transformers, Combined Current/Voltage Transformers and Station Service Voltage Transformers are designed to transform high current and high voltage levels down to low current and low voltage outputs in a known and accurate proportion specified by the product nameplate ratios. Buy Current Transformers.

When an alternating current flows through the primary winding, a magnetic flux is created which then induces an alternating current in the secondary winding.

Current transformers (CT) are devices that are used to transform the current from a high current into a lower current so that the power can then be measured and controlled. Standard Measuring CT. Standard measuring current transformers are used in conjunction with ammeters to measure high currents which are stepped down to a standard output ratio of either 5 A or 1 A.

Current transformers and accessories Obviously currents of several hundreds to thousands of Ampere cannot be directly digitally measured. The transformers consist of a core, a primary and a secondary winding. Flex-Core® maintains a large in-stock inventory of Current Transformers, including Split-Core, Solid-Core, Low Voltage, Medium Voltage, Clamp-On, and Rogowski Coils for most common applications..
