    T&R ART3V 3 Phase Relay Test Set

    The T&R ART3V 3 Phase Relay Test set, replacing the DVS3 MK2, introduces impressive new adaptable features making it a remarkable addition to an already outstanding range of relay test equipment. With higher output voltages, a superior level of accuracy and control, the ART3V implements a full colour LCD screen for extensive and easier to understand test details. The intuitive user interface is a vast improvement over the DVS3 MK2, granting simple testing of complex voltages and loss of mains protection systems.

    Improved accuracy and stability prove to be just some of the ART3V's commendable new properties. Built to be a reliable voltage source for relay testing, the tester has been designed using only the best in contemporary digital technology, generating a highly stable and accurate output with very low distortion. Individually adjust each phase output for voltage, frequency and phase angle with a simple user interface within defined interactive menus. The customisable values can be entered with the capacitive keypad or finely carved using a smooth rotary encoder.

    Using the ART3V, create bespoke test procedures for step changes of all output variables at pre-determined times. Conversely use the response of the relay under test to initiate handsfree automatic timing. Store results in a .CSV format within the included USB memory key for simple spreadsheet creation and add test comments with a suitable USB keyboard. The ART3V is ideally suited to testing both G59 protection and G99 schemes, 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
    • ROCOR relays (df/dt)
    • Vector surge relays
    • Transducers

    The ART3V* can be used to test protection circuits including:

    • Directional relays
    • Distance Protection
    • Power Transducers

    *In conjunction with the ART3C or a current source (such as the 200ADM-P)

    The ART3V has a 6.5 inch, colour back-lit LCD display providing an easy to read user interface. Select menu options through dedicated buttons on the panel for an easy change of mod. All information, including contact set status and a phasor diagram is displayed.

     *All output ratings are based on an ambient temperature of 25˚C

    Timing System

    The timing system on the T and R Test equipment ART3V is flexible and transparent with different modes of operation. In INTERNAL START mode step changes of any quantity will automatically reset and start the timer when the change is applied. The timer then stops on a change of state of either contact set. Contacts can be used to trigger the timer based on external relay changes. Also, more complex timing functions are handled by the Fault Config mode.

    Two contact inputs are provided, both of which have LEDs and an icon on the display to show the contact state. The contact inputs auto-select for normally open or normally closed contacts. A DC voltage can also be used to trigger the timer using the Vdc contact.

    • Timer Resolution: 1ms
    • Timer Accuracy: ±0.01%rdg+2d
    • Contact O/C Voltage: 24V
    • Contact S/C Current: 20mA
    • Vdc Input Range: 24-240Vdc

     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.

    Protection and Safety

    The ART3V Relay Test System is CE marked and is designed to meet the requirements of BS EN61010 and EMC tested to BS EN 61326. The outputs are protected by overcurrent and thermal trips, and the contact inputs are protected by PTC thermistors. The phase lock current input is fuse protected, and the voltage input is impedance protected. An earth terminal is provided for connection to a local earth.

    Modes of Operation

    Output Adjust

    This mode allows full control of frequency, voltage and phase. Each voltage, phase and frequency can be controlled together or independently. All parameters are continuously variable using the adjust control, and step changes of any value may be made. The timer automatically resets and starts when a step change of value is entered, and stops if either contact input changes state. Step changes of phase for testing Vector Surge relays are easily generated in this mode.

    • Frequency Range: 30-999.99Hz
    • Frequency Resolution: 0.01Hz
    • Frequency Accuracy: ±0.05%rdg+2d
    • Phase Resolution: 0.1º
    • Phase Accuracy: ±0.3º phase to 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, or an external voltage or current. This mode allows testing of directional and distance protection in conjunction with an external current source.

    • Phase Lock Range: 45-65Hz
    • External Voltage Ref: 20-250V AC
    • External Current Ref: 0.2-5A AC
    • Phase Resolution: 0.1º
    • Phase Accuracy:
      • ±0.3º phase to phase
      • 3.0º reference to output
    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.

    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. The rate of change may be continuously varied to find the relay setting or stepped to time the relay. The output may be set to either sweep continuously or generate single sweeps with timing.

    • Frequency Range: 45 - 70Hz
    • Frequency Resolution: 0.01Hz
    • ROCOF Range: 0.001 - 10.000Hz/s
