• determine the full-load current of a transformer given the kVA and voltages of the primary and secondary windings. • identify the common types of transformers from their schematic diagrams. • read transformer winding diagrams and connect a transformer for the desired primary lowers the line voltage to 24 V for the control circuit.

The Smart Substation | Transmission & Distribution World

Traditionally, these measurements have been performed by instrument transformers such as potential transformers (PTs), capacitive voltage transformers (CVTs) and current transformers (CTs). PTs and CTs are wire-wound devices with a secondary winding to reduce the voltage or current to safe levels for use in the protection and control schemes.

How reactive power is helpful to maintain a system healthy

When reactive power supply lower voltage, as voltage drops current must increase to maintain power supplied, causing system to consume more reactive power and the voltage drops further . If the current increase too much, transmission lines go off line, overloading other lines and potentially causing cascading failures..
