CT (CURRENT TRANSFORMERS) IN ELECTRICAL DISTRIBUTION … the low voltage system where current flow limit within 100A, is possible to measure directly or whole current metering system. For low voltage system current more than 100A and all high voltage system, current measured by using CT. Actually CT takes a reduced portion of current which is proportional to flowing total current in the load circuit.

Solutions for Electrical Substation Maintenance - SMC transformer testing is also an important part of electrical substation maintenance.
