YOKOGAWA INSTRUMENT CURRENT TRANSFORMERS

Instrument transformer is a general term for voltage transformers and current transformers that are used with electrical instruments. The main purpose of instrument transformers is to extend the measurement range for electrical quantities (voltage, current, power, power factor) on large-current and high-voltage circuits. They serve to convert currents and voltages to levels that are suitable for measurement, and to insulate the instrument, etc. from high-voltage circuitry. YOKOGAWA makes a variety of standard instrument transformers. These include the top class (Class 0.1) current transformer 2243, the Class 0.2 6600V circuit instrument voltage transformer 2262, the 6600V current transformer 2242, instrument voltage transformer 2261, and current transformer 2241.
