Product Description
Microcomputer relay protection tester is a new type of miniaturized microcomputer relay protection tester realized by widely listening to the suggestions of users, summarizing the strengths and weaknesses of current domestic similar products and fully using currently advanced microelectronics technology and device on the basis of referring to the Technical Specifications of Test Equipment Based on Microcomputer for Relaying Protection (Exposure Draft) issued by the ministry of electric power. Microcomputer relay protection tester has self-prepared large screen LCD and flexible and convenient rotation mouse controller. The independent operation of single machine already has powerful functions and can carry out most of the tests, while the operation connecting with the computer has more powerful operation functions. It also has small volume and high accuracy. It has both the outstanding performance and advanced function of large testers and the advantages of small and exquisite appearance and flexibility, convenient operation, high reliability and others of small testers with high cost performance. It's a good handy tool for relay protection workers.
