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 Sense Magnetics
-
Current sense magnetics are used as a low loss method for sensing AC current in a circuit and also provide electrical and safety isolation between the source of the current and the measurement circuit. The key parameters for a current sense transformer are the rms current rating (to ensure it does not overheat in the application) and the safety and voltage isolation (to ensure it conforms to the end-application requirements).

Device Current Waveform Analyzers
-
The dedicated Current Sensors measure from 100 pA level dynamic current up to 10 A with a maximum of 200 MHz bandwidth. The mainframe acquires the signal from the sensors by a maximum of 1 GSa/s sampling speed and 14-bit and 16-bit wide dynamic range. This combination allows you to measure quite wide range of dynamic current, for example, from standby/sleep state to active state, at a single measurement. In addition, the wide bandwidth and the high speed acquisition enable you to measure high speed pulse response even less than 100 ns previously very difficult with existing instruments.
