Answer Posted / Kritishwar Pathak
A composite error in current transformers refers to an error that results from the combination of several individual errors, such as winding error, core loss error, and magnetizing current error. These errors can occur in both metering CTs (used for measuring current) and protection CTs (used for circuit protection). The composite error is significant because it affects the accuracy of measurements or the effectiveness of protection devices.
