When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...
Residential and commercial circuit breakers face three major challenges: detecting arc faults reliably, reducing false trips ...
The circuit in this Design Idea detects short-circuit faults or excess-current conditions in line-operated equipment, such as a UPS (uninterruptible power supply), across an isolation boundary. If the ...

This is a CMOS IC (CD4033) based circuit which can be used to detect presence of AC mains voltage without any electrical contact with the conductor carrying AC current/voltage. Thus it can be used to ...
OVERCURRENT DETECTOR - the circuit introduced here is a simple and fast-responding overcurrent detector for protection of low-voltage applications. Unlike dedicated hot-swap controllers that impose a ...
