Voltage selection scheme checks. We don’t have BUS VT , As VTs VTs are not provided for monitoring the Bus Voltages, a separate LV scheme (Voltage Selection Scheme) is utilied to displa! BB voltages in the "#$%S&A'A and also for maing proper selection of us ar voltage ! maing use of line VTs secondar! for s!nc closing*
Selection of a particular line voltage as the respective usar voltage is accomplished in accordance accordance +ith the connection of usar disconnector &B to the respective usar* $nterposing VTs VTs +ith -.- ratio is also inserted in VT secondar! circuit for electrical electrical isolation of VT secondar! * The scheme is designed to get proper selection of usar voltage(running voltage) depending upon the s+itching of a particular disconnector/&B comination*
