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.

Eddy Current Dynamometer
EC Series
-
Specifically designed for small displacement diesel engines, the Eddy Current (EC-Series) engine dynamometer features in-line eddy current absorption units in a robust, compact frame. The air-cooled eddy current absorbers eliminate the need for an expensive water recirculation system and most engines being tested can be cooled with a standard closed-circuit radiator system. This compact air-cooled design results in a minimal environmental impact and the ability to be easily relocated with no need for a permanent installation. When combined with PowerNet LT, our fully automated dynamometer control system, all of your testing needs can be performed at the touch of a button.

Impulse Current Measuring Shunts
ICMS
-
The Impulse Current Measuring Shunts ICMS are new designed tubular shunt types with best response behavior to match the high performance of the TR-AS digital recorder for comparative current measurements. A 1st partial response time less than 10ns and a settling times less than 20ns show the advantage of these shunts. They show no initial overshoot peak, no oscillations and do not need compensation box to optimize the transient behavior as known from e.g. cage shunts.

SparkFun Current Sensor Breakout
INA169
-
The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.
