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.

0-100A output current True RMS metering with single cycle capture Auxiliary DC and AC output Multi-function auto-ranging timing system Current limit mode for fine control Automatic mains voltage selection Thermal and over-current protection The 100A/E mk3 secondary current injection test set has been designed to give the maintenance and commissioning engineer a large number of facilities in one self-contained instrument.The unit is portable, compact and simple to use. The mains supply for the unit is either 240V±10% or 115V +10% -6% at either 50 or 60Hz. Full load can be obtained at the supply voltage extremes. The current and voltage outputs are independently controlled and metered. The output current and voltage are displayed on large, clear panel instruments. An additional four range CT is provided, extending the ammeter range down to 0-100mA. All of the outputs are fully isolated by means of double wound transformers. The timing system on the 100A/E is very flexible, without compromising ease of use. Four modes of operation and two contact inputs are provided allowing for a wide range of events to be timed. Both contact inputs automatically select for normally open or normally closed contacts. Operation of the different timing modes is described overleaf. Internal start mode starts the timer when the ‘ON’ pushbutton is pressed, and stops the timer when the first contact set changes state. This mode is ideally suited to timing over-current relays. Single contact mode starts and stops the timer on the first and second changes of state of the first contact set, and dual contact mode starts the timer from the first set of contacts and stops it from the second set. These modes allow reset and re-close times of protective devices to be easily measured. The final mode of operation of the timer starts the timer when the current exceeds 20% of the selected metering range, and stops it when the current falls below 20%. This allows the timing of trips with no auxiliary contacts such as miniature circuit breakers. Automatic control has been provided such that all outputs can be switched off once the device under test has operated. The automatic control can be switched in or out of circuit for all outputs, enabling setting up procedures to be carried out. The instrument is housed in a robust case complete with a protective cover and fold-away carrying handles. The current output on the unit has eight ranges, allowing the selection of output voltages up to 150V and output currents up to 200A. The voltage output on the unit has three ranges, allowing the selection of output voltages up to 500Vac and 250VDC. If using a 100ADM-F with the 100A/E mk 3 unit you will need to to order A0006-0010 lead set. The output of the 100A/E mk3 secondary current injection test set is a true RMS analogue system with separate instruments for current and voltage. AC current is metered by a dual scaled ammeter reading 0-1A and 0-5A. AC voltage is metered by a dual scaled ammeter reading 0-300V and 0-600V. The output may be automatically switched off at the end of the test to safeguard the relay under test. This is available for both the voltage and current output.

5kA maximum output current (higher overload currents for 2s) Multi-function digital timing system Digital true RMS memory ammeter Solid state switching 200A, 2000A and 5000A loading units Three range outputs on loading units Rugged, compact design Optional trolley mounting of system Secondary injection up to 100A Auxiliary metering input Direct reading CT ratio and polarity The CU-Ps primary current injection test set is ideally suited to commissioning and maintenance testing where very high currents are required. The system consists of separate control and loading units for maximum flexibility. The control unit contains all control and metering circuitry, and is linked to the loading unit by control and metering cables. The control unit may be used with one of two loading units providing between 5000A or 6000A for 5 minutes or up to 10 or 12kA for short periods. Each loading unit has two outputs which may be connected in series or parallel for maximum flexibility. For example, the PLU-6k may be configured to either give a maximum current of 3000A at 6.6V or 6000A at 3.3V. The control and loading units are each housed in tough steel cases fitted with castors and protective lifting handles. The loading units have a small plan area to allow them to be positioned as close as possible to the test object, minimising power requirements and maximising the available current. The CU-Ps control unit is shown here with a PLU-6k loading unit. This combination may be used to inject currents of up to 6000A for 5 minutes or 12000A for 1 second. The CU-Ps primary current injection test set is ideally suited to all primary current injection tasks, including testing under and over current relays, circuit breakers and CT ratio testing. The control unit is rated at 20kVA and has digital metering. A memory facility is provided on the metering to hold the current reading when the output trips or is switched off. The current is automatically switched off when the device under test trips. The CU-Ps systems have a high accuracy timing system with 1ms resolution. Selection for normally open or normally closed contacts is automatic, and the status of the contacts is shown on the front panel. Timing modes are available for under and over current devices, reclosers, under and over voltage devices, current trips and circuit breakers. The AC output current is metered by a true RMS memory ammeter (acquisition time 20ms) with a liquid crystal display. The current metering has 3 ranges corresponding to 10%, 50% and 100% of the maximum rating of the loading unit. In addition, a 200% metering range is enabled in pulse mode for the 0.2s, 0.5s and 1s settings only. The CU-Ps systems have a flexible timing system with two contact inputs and 5 operating modes. Each contact circuit automatically selects for N/O or N/C contacts, and the status of each contact input is shown by an LED. The timing channels may also be triggered by a dc voltage between 24 and 240V. *Pulse mode applies current to the load for a maximum of the specified time. If contact set 1 changes state or the current drops below 20% of the metering range during the pulse time, the timer is stopped. The maximum output current is increased in pulse mode. The maximum obtainable current is set by the impedance of the test object and output leads. **Current operated mode is used to time circuit breakers with no auxiliary contacts. The timer is started when the current exceeds 20% of the selected metering range (e.g. 1000A on the PLU-5k 5000A range). The timer stops when the current falls. All test results from the CU-Ps can be stored in a USB memory key. The unit has a real-time clock to time and date-stamp all results. To log the results, first enter a comment for your results using the optional keyboard, and then select AUTO STORE. Whenever the timer stops, the time, current and all other parameters are added to a spreadsheet file on the USB key. You can then view the current set of results on the display or take the USB key out and open the file on your PC. All results are stored in a folder on the USB key named with the test date in a file named with the time. The CU-Ps primary current injection test sets and loading units are CE marked and are designed to meet the requirements of BS EN61010. The system is protected by electronic trips on the outputs, circuit breaker and fuse on the mains input, and a circuit breaker on the control unit output. The unit also has a duty cycle trip on the loading unit output and thermal protection. WEIGHT 115 kg DIMENSIONS 660 × 400 × 740 mm OPTIONAL ACCESSORIES A range of output lead sets are available to complement the CU-Ps system with current ratings between 3000A and 6000A.
