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.

LV Iron Core Shunt Reactors
-
Iron core Shunt Reactors act as an absorber of reactive power to increase energy efficiency of the power system. Shunt Reactors are used in order to compensate capacitive reactive power generated by long and lightly loaded transmission lines as well as underground cables, thus allowing the flow of more active power through the system and avoiding over voltages. Shunt Reactors can be directly connected to the power line or to a tertiary winding of a three-winding power or distribution transformer.

SparkFun Current Sensor Breakout
ACS723 (Low Current)
-
The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!
