INTRODUCTION

In its present state, this chapter deals only with conventional wound type (or having wound parts) instrument transformers intended to be used with measuring apparatus or protection devices. In the future, it will be updated to take into account the introduction of new types of instrument transformers with a more general title.

Unless otherwise stated, the functional characteristics, such as errors, rated currents and so on are valid in the case of sinusoidal currents and voltages under steady-state conditions and the values of current and voltages appearing in the terms and definitions are r.m.s. values.
