Patent

CA 2123600

A personnel protection system for electrical connections is disclosed, which is of the type that differentially senses the cur- rent flow between the power lead (50) and the return lead (52) (or between two power loads) is provided with an unbalancing im- pedance (70) which makes the current difference between the two leads sufficiently high to trip the device (48) and cause the pow- er to be disconnected. A utilization device (64) is similarly provided with an imbalanced impedance (80). However, that imped- ance is calculated to counteract the current imbalance caused by the first impedance (70), so that when the cable is connected to the utilization device (64), the current balance between the two conductors (50, 52) is restored, and power connection is main- tained in the cable. Thus, the system does not provide continuous power unless predetermined conditions considered safe for sec- uring the power are fully satisfied.
