T&R ART3V Relay Test System - Improved accuracy, stability & features

This product is now obsolete. To find out more about other Relay Testers available CLICK HERE.

The T&R ART3V Relay Test System has been designed for testing voltage and frequency protection relays. It generates a three phase voltage output from a single phase supply, and may be used in conjunction with a current source to test directional relay protection.


T&R ART3V Easy to Understand Interface

The ART3V features output voltages with a higher and have a finer level of accuracy and control than its predecessors; and boasts a large, full colour, back-lit LCD display (6.5") providing even more test detail! - Including contact set status, and a phasor diagram.

Its user interface is an improvement of the DVS3 mk2 allowing simple testing of complex voltage and loss of mains protection systems; And defined menu options are selected by dedicated buttons on the panel, allowing easy mode change. Values may be either typed in at the capacitive keypad or finely varied using a smooth rotary encoder.

T & R Test Equipment ART 3V Relay Test System for G99 Testing


T&R ART3V Key Features:

  • Provides highly stable and accurate output with very low distortion 
  • Each phase output is individually adjustable for voltage, frequency and phase angle
  • Bespoke test procedures can be created for step changes of any output variable at set times or with automatic timing of the response of the relay under test
  • 3-f Voltage output from 1-f supply
  • 0-450V f-N output voltage
  • 20VA/phase maximum output
  • Variable Frequency 30-999.9Hz
  • Phase shift ±180.0°
  • Multi-function timing system
  • USB keyboard for comment
  • USB data storage
  • Automatic mains voltage selection



T&R ART3V Applications:

  • G59/G99 protection, including loss of mains protection
  • Vector surge and df/dt (ROCOF) relays can be simply tested and timed, as well as other protection requiring one to three voltages, including:
    • Under and over frequency relays
    • Under and over voltage relays
    • Synchronising relays
    • df/dt & ROCOF relays
    • Vector surge relays
    • Transducers


In conjunction with the ART3C or a current source (such as the 200ADM-P), the ART3V can be used to test protection circuits, including: Directional relays, Distance protection, Phase angle relays, Power relays, Power transducers
