Power protection relay DMP300

ACdigitalmodular

It is applicable to the protection, measurement, control and RTU of 110kV and below power generation system, power transmission and distribution system. It can be installed in panels or locally mounted on switchboards. Product features ◆ High-performance high-reliability hardware platform It adopts dual-CPU (32-bit DSP chip) structure with industrial grade platform design, coordinating with reliable embedded real-time multiple task operating system, which guarantee the real-time and rapidity of computer, rich interface and operability. ◆ High anti-jamming case It has integral panel, reinforced unit, which can resist strong vibration with strong an-jamming design that suitable for severe environment. The measurement, protection AI isolation sampling channels are fully independent. The specialized analog and digital filtering design and high-accuracy AC sampling technology meet with the requirement of both measurement accuracy and the large dynamic range of protection action. The protection algorithm is mature, sound and reliable. ◆ Hardware modularity The hardware modular structural design has strong interchangeability and easy to maintenance, which greatly reduced the spare parts. ◆ Generalized function design The software has function modular design. Each function can be configured flexibly to meet with different requirement. The device can access 8 sets of settings and store the information of last 200 SOE. The high-capacity fault recording has maximum time for 20s fault record. The DI, DO can be on-line defined by user to meet with the logic configuration of different conditions.
