IS 4146 : 1983 Application guide for voltage transformers

1 Scope

1.1 This guide covers application of voltage transformers foruse with both electrical measuring instruments and meters(measuring voltage transformer) and electrical protective devicesincluding broken delta voltage transformers for the application ofdirectional earthfault protection (protective voltagetransformers). Reference has also been made to the use of voltagetransformer for the dual purpose of measurement and protection.

1.2 This guide does not cover application of capacitor voltagetransformers and phase shifting voltage transformers.
