PLB-1 generator overcurrent and overvoltage protector circuit block diagram

The PLB-1 generator overcurrent and overvoltage protector is a product of Shenzhen Xuzhen Electric Technology Co., Ltd. It is
an intelligent control protection device specially designed for the protection of small hydropower station generators in view of the problems existing in shell relay protection. This
monitoring device uses an eight-bit microcontroller as the core and adopts a precise control algorithm, so that the device has excellent control performance and control
accuracy.
  The protector integrates overcurrent, overvoltage, undervoltage protection and delay control. The overcurrent protection has an inverse time limit function and a trip maximum
current memory function, which can completely replace the traditional multiple relay protection modes, simplifying installation and improving efficiency. reliability. At the same time,
the device also has a digital display function for generator voltage and current values, which is convenient for observation and operation, and is very convenient to use. The circuit block diagram
  of the PLB-1 generator overcurrent and overvoltage protector is as shown in the figure
