SMC PTE-300-V Three Phase Relay Test Set

Overview

The SMC PTE-300-V is a robust three phase relay test set designed for comprehensive protective relay testing in laboratory and field environments. It comprises three independent output channels that can be selected as voltage or current sources, enabling operation as a complete single-phase unit or as a synchronized three-phase voltage/current generator from a single-phase mains input. The compact and rugged design incorporates modern digital microprocessor technology with Intelligent Generator Modules (IGM) for precise, stable, and low-distorted output independent of supply voltage variations.

Key Features

• Three independent 100 VA output channels with total 300 VA power
• Variable three phase voltage to 3 x 300V or current up to 3 x 8A
• Variable frequency from 40 to 420 Hz with adjustable phase angle (0–359.9°)
• Fully isolated and electronic reversible outputs
• Completely programmable with software-based calibration
• Optional computer connection for automatic testing and Windows compatible software control
• External frequency or phase reference input

Applications

• Testing of three and single phase Generation and Interconnection Relays
• Three phase voltage testing combined with current injection sets
• Complete single phase unit operation with reversible voltage, current, and phase angle outputs
