Instrument transformers technology can also empower the grid with auxiliary power supply and highly precise power quality measurements. Types of Instrument Transformers Current Transformer (C.T.) Manufacturer of transformers serving the commercial and industrial marketplace requirements for switchgear, motor control and switchboard transformers. and P.T. Prentice-Hall of India, 1988.Golding, E.W. The measurement of such very large electrical quantities, can be made possible by using the Instrument transformers with these small rating measuring instruments. instrument transformers supplied by Trench for customers on all 5 continents every year.When used for protection purposes, the instrument transformer outputs must accurately represent the transmission line values during both steady-state and transient conditions. More ever the damaged measuring instruments can be replaced easy with healthy standardized measuring instruments.Instrument transformers provide electrical isolation between high voltage power circuit and measuring instruments. “Electrical Measurement and Measuring Instruments”,.
