Low Voltage Current Transformer | OEM/ODM & Wholesale Price

A Low Voltage Current Transformer is an instrument transformer used to scale primary current in a low-voltage circuit to a lower, measurable secondary current for metering and protection equipment.

A Low Voltage Current Transformer couples magnetically to the primary conductor and provides a proportional secondary current that electricity meters or data acquisition modules can measure to calculate load current and related electrical parameters.

Selection depends on installation constraints. Window-type and ring-type structures are typically chosen when the conductor can be routed through the transformer during assembly, while open-type structures are used when quick installation on an existing conductor is required.

An open-type Low Voltage Current Transformer is positioned around the conductor using the opening mechanism and then secured according to the installation method used in the panel. Wiring is then connected to the intended meter, data acquisition module, or protection device input.

A Low Voltage Current Transformer is used with protection devices when the secondary current signal is required for protection functions such as monitoring, tripping logic, or current-based protection schemes within protection relays or related protective equipment.
