High Frequency Current Transformer
HFCT Ø 140mm
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).

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.

Combinational Base Test Platform
6TL24
The 6TL24 is the Base platform ideal for Combinational test (ICT+FCT) in low to mid-volume, high-mix electronics productions. A dual-stage pushing mechanism will allow performing both, the FCT and the ICT test, without the need of changing the test platform and with a low cost fixturing technology. To do so, the exchangeable cassette fixture must be designed with two-level probes. IN the 6TL24, the second level is reached thanks to a pneumatic actuator.
