Description
Overview
The SMC TRES is a portable test system for protective relay testing, comprising two independent units with reversible voltage and current outputs. It provides independent control of amplitude, phase angle, and frequency for comprehensive testing of single and three phase protection relays in laboratory and field environments.
Key Features
- Three phase current output 3 x 50 A, three phase voltage output 3 x 300 V
- Six reversible output channels, switchable between voltage and current modes
- Variable phase angle 0° to 360° independent per channel
- Frequency range 40 to 420 Hz with programmable ramp (0.01 to 10 Hz/s)
- Up to 7th harmonic selection per phase
- Dynamic and transient testing capability (bandwidth 0.5 to 5000 Hz)
- Fully isolated 100 VA output per channel
- Manual control and computer programmable with optional software
- IP-65 portable enclosure with Closed Case Calibration
Applications
- Testing three and single phase protection relays
- Fault simulation and dynamic transient testing
