Error compensation of current transformers in high voltage networks

An error compensation technique for measuring current transformers is described. An example is shown for current transformers installed in 150 kV switching devices. Initial ratio errors in the order of 4% and phase shifts around 20 min were reduced to 0.1% and 6 min after the compensation.
