Current Protection Relay
The main earth fault protection relays in distributions systems, power stations & large manufacturing / processing plants can fail to detect a high impedance break down to earth causing hazard to human life & potential damage to plant & equipment. In these & other situations demanding extra sensitive earth fault protection, using solid state techniques, can be applied to detect earth currents down to 0.5% of the CT nominal current.

SparkFun Current Sensor Breakout
ACS723
The SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for 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!

Burden Set – Current
BSC-102
The industry has recognized the actual load (burden) on CTs is lower than the standard ANSI burdens allow. So a new IEEE Specification (IEEE C57.13.6) accommodates that fact by introducing two new burdens and two new accuracy classes. This new specification address “High Accuracy”CTs.

Multi-Channel, Programmable Current Source
CS-48-100
The Model CS-48-100 is a multi-channel, programmable current source. Developed for both semiconductor and digital superconductor electronics, it is computer-controlled and features 48 low noise current source outputs. Each source output has the capability to both set and read back currents and can be set to a zero current high Z mute state. Each of the 48 sources are optically coupled for control and are sourced from their own secondary winding for complete galvanic isolation. The device consumes a maximum of only 80 W and handles a maximum load current of 4.8 A total over all outputs. Operating over a range of 0-100 mA on each channel, the device features accuracy of +/-25 ?A. The mute state can be set thru a rear panel interlock or from the front panel button for maximum circuit protection. The unit can be mounted in a standard-sized rack.

AC Current Sensor
RCTi and RCTi 3ph
The RCTi & RCTrms sensors convert ac current to an isolated 0-5V voltage or 4-20mA current loop. TA5V-5A allows compatibility with existing 1A or 5A CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available RCT current ranges are 0-100A to 0-50,000Apk. Both RCTi and RCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted wave shapes - using a flexible clip-on sensing coil. The RCTs are available as single and three phase models.
