differential relay

基本解释

The Model 24 Snap Acting Relay is a highly accurate differential relay with snap-acting switching.
示范24换向阀是一个高度精确的管理差动继电器长效开关。
The uses, operating principle and main requirements of the current transformer for differential relay with high impedance were described.
叙述了高阻差动继电器用电流互感器的用途、工作原理和主要要求。
The differential relay compares the currents and picks up when there is a difference in the two, which signifies a fault in the zone of protection.
差动继电器对电流进行比较，如果存在不同则表示受保护区域内有故障存在。
