Introduction

    With built-in microcomputer, the instrument could be used separately from the laptop . Intelligent photoelectric rotation mouse, large screen LED LCD display, could be connected to laptop. All PC soft wares are WINDOWS soft wares, with powerful test capabilities and perfect test report processing functions .

• Line protection (distance test, zero-sequence test, impedance test, reclosing test)

• Differential protection, Over-current protection, AC/DC current, voltage relay

• Power direction relay, Time relay, Indicating relay

• Synchronizer, Harmonics test, Frequency and low-cycle low voltage load shedding protection
