Figure 1 Inductively coupled trigger circuit employs a standard current sense transformer (T1), large burden resistor (R2), input comparator (U1), flip-flop (U2), and output comparator (U3). Pulse ...

Current transformers require a resistive load (ballast) in order to output the desired signal voltage. Avoid operating them without a load resistor as they can generate self-destructive voltages in ...

Once the current transformer is magnetized a demagnetization process is necessary in order to remove residual magnetism. This can be achieved e.g. by applying an AC current with similar strength as ...

Current transformers are an efficient way to measure current. Since the burden resistor is reflected to the primary by 1/N 2, the resistance seen in the circuit being monitored can be very small.

A home-brew current transformer made from a split ferrite core and some magnet wire is the sensor, and a couple of op-amps and a 555 timer make up the detection and alarm part.

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer.

The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...
