DTP510A microcomputer protection

DTP510 series relay protection devices are mainly developed for the application of central cabinet system. It has phase-to-phase current quick-break, overcurrent, and inverse time overcurrent protection with three action characteristic curves, overload, overvoltage, low voltage, zero sequence overvoltage, reclosing, definite time limit zero sequence overcurrent protection, inverse time zero sequence Over-current, low-voltage zero-sequence protection, transformer body protection and non-electricity protection tripping functions, as well as monitoring functions such as multi-electricity measurement, remote control, and remote signaling. This microcomputer protection device uses a highly integrated microprocessor with no bus chip to process the signals from the current and voltage transformers, and controls the output of the device through digital logic operations. The device has a compact structure, a sealed case, a maintenance-free design, and good anti-interference performance. It is v
