Product Overview

Product Features

  • The main features of the microcomputer-based relay protection tester are as follows:
  • Equipped with the user-friendly Windows XP operating system, the human-machine interface is intuitive and easy to operate, enabling quick and efficient task completion. To further enhance usability, a wide range of keyboard shortcuts have been defined, allowing users to perform operations with a single key press.
  • High-performance embedded industrial control computers paired with large, high-resolution color TFT LCD displays provide rich, intuitive information, including the equipment’s current operating status, prompts for the next step, and various help messages.
  • Equipped with an ultra-thin industrial keyboard and a touch-enabled mouse, it allows users to perform various operations via the keyboard or mouse just as they would on a standard PC.
  • Equipped with an external USB interface, it enables convenient data access and software maintenance.
  • All test items can be completed without the need for any external equipment; test data are automatically displayed and recorded, and vector diagrams and characteristic curves are generated.
  • A high-performance D/A converter is employed, delivering waveforms with high accuracy and excellent linearity, as well as superior transient response and amplitude-frequency characteristics. Waveform accuracy and other performance specifications are consistently met across the entire measurement range.
  • It can directly output AC voltage, AC current, DC voltage, and DC current, with adjustable amplitude, phase angle, and frequency.
  • The power amplification stage employs a new high-power, high-fidelity linear amplifier circuit, delivering substantial output power with minimal ripple and interference. Even at maximum output current, the waveform remains undistorted and free of clipping.
  • The digital input interface can automatically accommodate both passive (dry-contact) and active inputs, and can also automatically adapt to the polarity of active inputs, operating reliably within an input voltage range of ±250 V.
  • It can perform a wide range of complex verification tasks, conveniently test and scan various protection setting values, store test data in real time, display vector diagrams, print reports, and more.
  • It features a meticulously engineered chassis design that is compact, offers excellent heat dissipation, is lightweight, easy to carry, and facilitates convenient flow testing.
  • The instrument features self-protection functionality, a well-designed thermal management system, robust and comprehensive protection measures, soft-start power supply, as well as built-in fault self-diagnosis and interlock capabilities.
