Care must be taken that the secondary of a current transformer is not disconnected from its load while current is in the primary, as the transformer secondary will attempt to continue driving current across the effectively infinite impedance up to its core saturation voltage. This may produce a high voltage across the open secondary into the range of several kilovolts, causing arcing, compromising operator and equipment safety, or permanently affecting the accuracy of the transformer. Dimensions To avoid personal injury or equipment damage, the secondary must always be short-circuited or connected to a burden. A solution for this problem is installation of our Test Terminal Block (TTB) that allows for safe testing, disconnection of the equipment leaving CT’s securely short-circuited. Using our test/disconnect terminals also reduces possibility of damage to Current Transformers.

In Depth IEEE Standard Requirements for Instrument Transformers C57.13, 17th edition. Electrical, dimensional, and mechanical characteristics are covered, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance and interchangeability of equipment covered and to assist in the proper selection of such equipment. Safety precautions are also addressed. Accuracy classes for metering service are provided. The test code covers measurement and calculation of ratio and phase angle, demagnetization, impedance and excitation measurements, polarity determination, resistance measurements, short-time characteristics, temperature rise tests, dielectric tests, and measurement of open-circuit voltage of current transformers.
