Overcurrent protection circuit for generator low voltage starting a
Source: InternetPublisher:奥特man123 Keywords: Low voltage protection circuit generator overcurrent protection Updated: 2020/09/22
When the load current of the generator is so large that the sensitivity of the protection device when reflecting external faults is very low, in order to improve
the sensitivity of the protection device, low-voltage starting over-current protection can be used . The circuit is shown in Figure 7-23. In the figure, KV ~
KV3 are low-voltage relays, TV is voltage transformer, and other symbols are the same as before.
