Instrument transformers comprise a large category of current and potential transformers for various voltage, frequency and physical size ranges. We have broken them up into several different groupings: low voltage, which are system voltages under 15kV; high frequency, operating frequency over 1kHz; and size ranges from board mount parts up to. supplying appliance, lighting, and power loads from electrical distribution systems. Standard distribution voltages are 600, 480, and240 Volts; standard load voltages are 480, 240, 208, and 120 voltage adjustment. Transformers rated 500kVA and higher have 1See page 10-45 for wiring diagrams. Dry Type Transformers Section 10 General.
