Das Ing.-Büro IMBUS hat in Zusammenarbeit mit der holländischen Firma I METER eine neue Düsenprüfanlage für Balgengaszähler entwickelt. Diese Anlage wird zur Kalibrierung und Eichung von Zählern in einer Produktionsstätte genutzt und ist für die Zählergrößen G1.6, G2.5, G4 und G6 ausgelegt. Die Entwicklung der Anlage basierte auf folgenden Prämissen: vollautomatische und schnelle Prüfung, Optimierung und Reduzierung der benötigten Zeiten für die Dichtheitsprüfung unter Berücksichtigung der Anforderungen der PTB-Prüfregel Band 25 sowie ein einfacher Aufbau des Düsennormals ohne komplizierte Düsenwechseltechnik. Es wurde besonderer Wert darauf gelegt, dass jede Düse während der Nutzung permanent auf mögliche innere und äußere Leckagen geprüft wird. Für die Generierung der 3 Durchflüsse aller 4 Zählertypen sind insgesamt nur 9 Düsen erforderlich. Die Dichtheitsprüfung ist in 3 Prüfmodi unterteilt: Prüfung der Zählerbänke mit den Anschlüssen, Prüfung der Durchflussverrohrung vor den Zählerbänken und Prüfung der "double block and bleed" Ventiltechnik zusammen mit der "Düsen-Bypass" Kontrolle. Durch diese Aufteilung war es möglich, die benötigten Dichtheitsprüfzeiten je nach Zählertyp auf 2 bis 4,5 Minuten zu begrenzen. Zur Gewährleistung der Genauigkeit werden Referenzbehälter eingesetzt. Die Anlage wurde 2008 von der Firma Akhnaton LTD in Sofia gebaut, welche auch die Programmierung der Steuerung übernahm. Der Prüfstand wurde durch die holländische Eichbehörde NMI zugelassen und steht in Polen, wo die dort in Lizenz gebauten Balgengaszähler im Rahmen einer EU Zulassung gemäß der MID geprüft werden.

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.
