When the catalogue doesn't have what you need — we design it from scratch.
Most instrument transformer applications are covered by standard catalogue products. But some are not. A steel plant measuring 50 kA primary current needs a CT with a non-standard ratio. A power trading company needs a CT at class 0.1 accuracy — tighter than any standard metering class. An export order specifies IEC test voltages and terminal markings that differ from IS standards. An OEM switchgear builder needs a CT that fits a specific panel dimension not matched by any standard product. These are the applications that Sakthi's engineering team works on under Customer Requirement Designs.
Typical applications
Custom-wound CTs and PTs for unusual ratios not in standard catalogues — for railway traction, steel plants, and special utilities.
Manufactured to customer drawings and quality plans for OEM transformer manufacturers, EPC contractors, and overseas buyers.
CT class 0.1 and 0.2S for power trading, state load despatch centres, and inter-utility settlement metering.
Special low-power instrument transformer (LPIT) and Rogowski coil designs for direct integration with digital protection IEDs.
