型号: DTM7033 

详细介绍：

The DTM7033, three-phase percentage biased differential relay, provides a particularly satisfactory solution for the protection of rotating machines against internal faults. These faults, generally caused by insulation ageing, require sensitive detection and fast clearing time in order to minimize their consequences.

DTM7033是三相比例制动保护装置，对于旋转设备内部故障的准确判断和快速启动保护有很好的作用。

In case of the transient response of the protected machine affects the accuracy of the current transformers to such a point that a significant false unbalance current is created, the relay's stability can be reinforced by adjusting the resistors inserted in the differential circuit.

通过调整差动回路的电阻，可以可靠的判断被保护设备在故障点由于不平衡产生的电流。
