SMC PTE-50-CET Three Phase Relay Test Set

Overview

The SMC PTE-50-CET is a three-phase electronic relay test set with three independent output channels that can be configured as current or voltage outputs. The unit can operate as a complete single-phase equipment or, with synchronized channels, as a three-phase current or voltage generator powered from single-phase mains input. It incorporates modern digital microprocessor technology with intelligent generator modules that produce highly accurate, stable, and low-distortion outputs independent of supply voltage variations.

Key Features

• Variable three-phase current: up to 3×50A
• Variable three-phase voltage: up to 3×150V
• Output power: 3×100 VA
• Variable phase angle: 0 to 359.9° (single or three phase)
• Independent harmonic selection per phase: up to 7th harmonic
• Reversible outputs
• Fully isolated electronic outputs
• Dynamic capability
• Completely programmable
• Built-in timer: 1 ms resolution
• Optional computer connection for automatic testing and software control
• Software-based calibration and adjustment

Applications

• Testing of three-phase motor protection relays
• Testing of three and single-phase overcurrent and differential protection relays
• Complete single-phase unit operation with voltage, current, and phase outputs
