Product Details：
The VIND-802 is a state-of-the-art three-phase relay protection test system designed to meet the rigorous demands of modern power system testing. Engineered with advanced DSP control technology and high-fidelity linear power amplifiers, this tester delivers exceptional accuracy (0.2 class) and stability for a wide range of applications, including transformer differential protection testing, fast bus transfer (FBT) tests, and backup power automatic switching (BZT) tests.
Its compact, lightweight design (13kg) and integrated software platform make it an ideal tool for both laboratory and field testing, offering unparalleled flexibility and reliability for electrical engineers and technicians.
Key Features
Flexible Output Configuration: Capable of 4-phase voltage and 3-phase current output, the VIND-802 supports various testing modes, including conventional relay testing and complex three-phase transformer differential tests.
High-Fidelity Linear Amplification: Utilizes modular linear power amplifiers instead of switching-type amplifiers to ensure smooth waveforms, minimal distortion, and no high-frequency interference, guaranteeing precision from micro to high current levels.
Advanced DSP Control: The output section is controlled by a high-speed Digital Signal Processor (DSP), enabling real-time signal processing, high-resolution D/A conversion, and superior waveform quality.
Comprehensive Software Suite: The accompanying software facilitates automated complex calibration tasks, fault recording playback, real-time data storage, vector diagram display, and report generation.
Dedicated DC Power Supply: Features an independent DC output channel providing stable 110V and 220V for auxiliary power testing.
Robust Protection & Connectivity: Equipped with comprehensive self-protection mechanisms (soft-start, fault self-diagnosis, output locking) and a full range of interfaces including USB for seamless PC communication.
