Using a Current Loop and Homogeneous Primary Winding for Calibrating a Current Transformer

Popis výsledku v původním jazyce

This paper presents two methods for determining the ratio error and phase displacement of a protection current transformer (PCT) with transformation ratio 10 kA/1 A and an instrument current transformer (ICT) with transformation ratio 20 kA/5 A. The primary conductor passed by a current (10 or 20) kA placed in the centre of the toroid is replaced by a current loop with 10 turns placed in the centre of the toroid. In the second case, the conductor is replaced by 10 turns uniformly distributed along the circumference of the toroid. The primary current (2 or 1) kA is measured in both cases using a toroidal current comparator, and the secondary current difference is evaluated by means of an ICT error measurement system. Besides the errors were measured also using an Omicron CT (current transformer) analyzer. These problems were presented in [1].
