  • Power Distribution: HV Instrument Transformers

    Credits: 2 PDH

    PDH Course Description:

    This course applies to current and inductively coupled voltage transformers of types generally used in the measurement of electricity and in the control of equipment associated with the transmission and distribution of alternating current.

    The primary function of an instrument transformer is stated as, “An instrument transformer is a transformer that is intended to reproduce in its secondary circuit, in a definite and known proportion, the current or voltage of its primary circuit with the phase relations substantially preserved.

    Topics:

    • Construction of Instrument Transformers
    • Service Conditions of Instrument Transformers
    • Types of Voltage and Current Transformers
    • Accuracy and Testing of Current and Voltage Transformers
    • Standard Burdens for Voltage and Current Transformers
    • Combination Units
