Description for: T&R ART 3V- Relay Test System

Key Features:

  • 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

The ART3V is ideally suited to testing G59 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


ART3V Specification

Output

The output of the ART3V has 4mm safety sockets for phases A, B, C and neutral.  The neutral connection may be omitted for a delta connection. The neutrals can be linked for a star connection using the provided accessory.

Timing System

The timing system on the ART3V is flexible and  transparent with different modes of operation.

USB Data

The ART3V can be connected to a USB keyboard for adding comments to tests.  Each test is stored to a USB memory key with each comment. The data is stored in a *.CSV format allowing it to be opened in all types of desktop PC spreadsheet software.


Modes of Operation

Output Adjust

This mode allows full control of frequency, voltage and phase.

Phase Lock Mode

The frequency and phase of the output can be controlled by an external reference in phase lock mode.  The reference may  be the mains supply to the ART3V, an external voltage, current.  This mode allows testing of directional and distance protection in conjunction with an external current source.

Fault Config Mode

Fault Config mode allows extra flexibility in testing complex timed events or several sets of values that must be applied to a relay in turn.  This mode allows three sets of values to be set in advance (pre-fault, fault, and post-fault values).  The ART3V may be set to switch from one state to the next on a change of contact or after a specific time.  In addition, the timer may be set to start or stop on any one of the state changes or a change of contact state.  This mode allows frequency, phase and voltage to be changed simultaneously if required. Test configurations can be save to USB.  More complex configurations can be loaded from the USB, such as a complete G59 relay test, such as relay stability tests.

df/dt and ROCOF (Rate Of Change Of Frequency)

Loss of mains protection often takes the form of a df/dt relay, sensitive to the rate of change of frequency over time.  The ART3V is able to generate a swept frequency output with accurate rates of change of frequency between preset frequencies.
