Description of the PTE-300-V Relay Tester

The PTE-300-V relay tester is equipped with three independent output channels, configurable as voltage or current. This flexibility allows the device to function as a comprehensive single-phase relay tester (managing voltage, current, and phase angle) or, with synchronized channels, as a three-phase voltage or three-phase current generator using a single-phase mains input. Its compact and rugged design incorporates advanced digital microprocessor technology, offering unmatched output performance in terms of power, accuracy, low distortion, and dynamic capability.

This innovative relay testing equipment enables users to conduct a wide range of specific relay test functions without needing additional accessories. All output signals are digitally generated, amplified, and precisely managed by the IGM’s (Intelligent Generator Modules), ensuring highly accurate, stable, and low-distortion outputs, regardless of the power supply.

Additionally, the PTE-300-V relay tester offers the option to connect to a computer for automatic relay testing using Windows-compatible software. The unit includes software for easy calibration and adjustment of outputs, allowing for closed-case calibration without manual hardware changes. This makes the PTE-300-V ideal for both manual and automated relay testing, whether in a laboratory setting or directly on-site.
