摘要：

Charge comparison is a new transmission line protection system. It compares local and remote quantities of charge, using a bi-directional communications channel. Charge comparison is a form of current differential relaying. Traditional current differential relaying schemes have three critical communications-related problems: protection lost if the channel fails, large channel capacity required, and precise channel delay compensation required. In large measure, charge comparison overcomes these three communications-related problems.
