An introduction to instrument transformer fundamentals, a discussion on power quality, and a detailed explanation of design considerations to assist in selecting an instrument transformer. A general overview of ABB’s current and voltage transformers.
Jul 25, 2019 · What Is An Instrument Transformer? Instrument Transformers are used to scale down the voltage or current to a standardized value when voltage or current is too large to be conveniently used by a measurement, protection, or control instrument. • CT’s: Current Transformers • VT’s: Voltage transformers, also referred to as "potential ...
Instrument transformers are designed specifically for use with electrical equipment falling into the broad category of devices commonly called instruments such as voltmeters, ammeters, wattmeters, watt-hour meters, protection relays, etc. Figure 1 shows some of the most basic uses for instrument transformers.

Instrument transformers (ITs) are designed to transform: voltage (Voltage (VTs) or Potential Transformers (PTs)) or current (Current transformers (CTs)) from the high values in the transmission and dis-tribution systems to the low values that can be utilized by low voltage current metering devices.
What is an Instrument Transformer? Instrument Transformers convert signal levels from dangerous (high voltage) or inconvenient (high current, or current at high voltage) to levels appropriate for metering. There are two fundamental types: CT’s (Current Transformers) PT’s (Potential Transformers.
