Product Description
■ Product Overview
The three-phase microcomputer-based relay protection tester employs a high-speed, high-performance digital control processor as its control unit and utilizes double-precision algorithms in its software to generate highly accurate waveforms of arbitrary phase. With an integrated design, the components are tightly coupled, resulting in short data transmission paths and a compact structure. This approach overcomes the issue of reduced output waveform resolution—common in laptop‑based test and control instruments—caused by long data communication lines and narrow bandwidth.
