Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.

Current Source
M151
-
Clarke-Hess Communications Research
The Model M151 is a stable high current calibrator up to 120 A. Basic accuracy is 0.035 %. It can be controlled viaRS232 or GPIB interface. The Model 151 can function in a simulated amplifier mode to increase the current capabilityof any multifunction calibrator. It is suitable for power meter calibration because it can be synchronized with the inputsignal not only in amplitude but also in frequency and phase. The current terminals are isolated up to 450 Vpk againstcase (protective earth).

DC Current Shunts
-
DC current shunts / standards are true 4-terminal devices that precisely measure DC currents from 10 A to 10,000 A. They use special alloys in the resistive elements which are supported on an insulating base for mechanical stability. The 9230A includes special features to reduce the effects of power dissipation and associated self heating errors. These shunts are designed to operate in air at full rated current. These are the best performing, and most widely used, DC metrology shunts in the world.
