We manufacture a wide range of electrical current transformers that is as per quality norms of IS 2705. Our tape insulated low tension electrical current transformers are available in the metering of 1P10, 5P10 and 10P10 in following types:
- Bar Primary Type (BPL)
- Wire Primary Type (WPL)
- Epoxy Type
The current transformers are classified as:
- Ring type: It has an opening in the center to accommodate a primary conductor through it. A conductor could be a busbar or cable.
- Bar-Primary type: The primary winding in this type of current transformer consists bar of suitable size and, material forming an integral part.
- Wound type: It has a primary winding of more than one full turn wound on the core.
Among above mentioned types, ring type or rectangular type current transformers are preferred over other types. Ring type current transformers are simple in construction, mechanically stronger and cheaper. We manufacture our electrical current transformers in ring type and rectangular type or in customized type as per the requirements with secondary 5A, 1A to suit in different panels.
Our electrical current transformers are used in following applications:
- To reduce line current to a value that is suitable for standard measuring instruments and relays
- To isolate the measuring instruments, meters and relays from line voltage of an installation
- To protect measuring instruments against short circuit currents
- To sense abnormalities in current and give current signals to protective relays to isolate the defective system
