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. Ideally suited to testing G59 & G99 schemes Step change of phase and df/dt Large 6.5” back-lit colour LCD Automatic mains voltage selection Fully Programmable test procedures Rugged case and weighs under 9kg The new ART3V Relay Test System brings new features to our range of relay test equipment making it far more adaptable. The new output voltages are higher and have a finer level of accuracy and control. The new full colour LCD provides more test detail, making it easy to understand. The ART3V user interface is an improvement of the DVS3 mk2 allowing simple testing of complex voltage and loss of mains protection systems. The ART3V has vastly improved accuracy, stability, and features. Designed to be the trusted and reliable voltage source for relay testing. The ART3V has been designed using the latest digital technology to generate a highly stable and accurate output with very low distortion. Each phase output is individually adjustable for voltage, frequency and phase angle. The unit is controlled by a simple user interface within defined menus. Values may be either typed in at the capacitive keypad or finely varied using a smooth rotary encoder. 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. The ART3V has a colour back-lit display to provide an easy to read user interface. Menu options are selected by dedicated buttons on the panel, allowing easy mode change. All information is displayed including contact set status, and a phasor diagram. The ART3V Relay Test System is ideally suited for testing 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 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/G99 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.

20kVA output capability 0-3kV to 0-15kV options available Accurate digital metering Key operated supply switch Dual overload protection Variable electronic trip 10-110% of rated output Voltage and current metering Optional 5s – 5min test timer External 24V interlock and zero-volt interlock Emergency stop switch The HV trolley2 series of units are high power AC flash test sets with a 20kVA output capability. Single Trolley Version The maximum output voltage can be customised to be any voltage up to 15kV. The unit is housed in a rugged aluminium enclosure with a cover to protect the control panel. It is mounted on wheels to allow easy movement within a production environment. The HV trolley2 is provided with accurate digital voltage and current metering and a variable electronic trip. An external interlock input is also fitted to the unit. Outputs are provided to drive 24V warning beacons. The HV output is connected to the test object by a high voltage cable 5m long.

0-50kV output voltage 5kVA output capability Key operated supply switch to prevent unauthorised operation Dual overload protection Variable electronic trip – 10-110% of rated output Voltage and current metering External interlock circuit Zero-volt interlock Visual indication of test piece failure The KV50-200 MK2 Test System is a high power, high voltage ac test set designed for insulation testing. This system is equally suited to both development and routine testing of electrical insulation systems and plant. The equipment consists of a control unit and a separate oil filled high voltage transformer, linked by 5 meter supply and control cables. The control unit is fitted with a comprehensive range of facilities for control, metering and protection. The system includes a secondary tap metering as standard to ensure accurate voltage metering. The output voltage and current are displayed on large, linear analogue instruments, and a variable electronic trip is provided, allowing the trip current to be set to 10-110% of rated output. The high voltage transformer is housed in an oil-filled steel tank fitted with swivel castors for mobility. The units use a low-discharge oil-filled bushing for the HV output. The KV50-200 MK2 Test System is equally suited to testing capacitive, resistive or inductive test objects. The output of the units are protected by variable electronic trips monitoring the output current, and a fixed over-current trip on the primary of the output transformer. The variable trip is adjustable in 10% steps between 10% and 110% of the rated output current. The input and control supplies are protected by fuses. An earth terminal is provided on the transformer which must be connected to a low impedance local earth.
