EN 60688:2013

Electrical measuring transducers for converting A.C. and D.C. electrical quantities to analogue or digital signals

IEC 60688:2012 applies to transducers with electrical inputs and outputs for making measurements of a.c. or d.c. electrical quantities. This International Standard is intended to specify the terminology and definitions relating to transducers whose main application are in industry; to unify the test methods used in evaluating transducer performance; and to specify accuracy limits and output values for transducers. The output signal may be in the form of an analogue direct current, an analogue direct voltage or in digital form. In this case, that part of the transducer utilized for communication purposes will need to be compatible with the external system. This standard applies to measuring transducers used for converting electrical quantities such as current, voltage, active power, reactive power, power factor, phase angle, frequency, harmonics or total harmonic distortion, and apparent power to an output signal. This standard is not applicable for instrument transformers that comply with IEC 60044 series; transmitters for use in industrial process applications that comply with the IEC 60770 series; performance measuring and monitoring devices (PMD) that comply with IEC 61557-12.

Elektrische Messumformer zur Umwandlung von elektrischen Wechselstromgrößen und Gleichstromgrößen in analoge oder digitale Signale

Transducteurs électriques de mesure convertissant les grandeurs électriques alternatives ou continues en signaux analogiques ou numériques

La CEI 60688:2012 s'applique aux transducteurs à grandeurs d'entrées et de sorties électriques destinés à mesurer des grandeurs électriques alternatives ou continues. La présente Norme internationale a pour objet de spécifier la terminologie et les définitions relatives aux transducteurs dont l'application principale est du domaine de l'industrie; d'unifier les méthodes d'essai utilisées pour évaluer les caractéristiques de fonctionnement des transducteurs; et de spécifier les limites de précision et les valeurs de sortie des transducteurs. Le signal de sortie peut être sous la forme de courant continu analogique ou d'une tension continue ou d'un signal numérique. Dans ce cas, la partie du transducteur utilisée à des fins de communication doit pouvoir être compatible avec le système extérieur. Cette norme s'applique aux transducteurs de mesure destinés à convertir des grandeurs électriques alternatives, telles que courants, tensions, puissances actives, puissances réactives, facteurs de puissance, angles de phase, fréquences, harmoniques ou distorsion harmonique totale, et puissances apparentes en signal de sortie. Ce standard ne s'applique pas pour les transformateurs de mesure répondant aux normes de la série CEI 60044; les transducteurs utilisés dans le processus industriel répondant aux normes de la série CEI 60770; et les dispositifs de mesure et de surveillance des performances (PMD) répondant à la norme CEI 61557-12.

Električni merilni pretvorniki za pretvarjanje izmeničnih električnih veličin v analogne ali digitalne signale (IEC 60688:2012)

Ta mednarodni standard se uporablja za pretvornike z električnimi vhodi in izhodi za izvajanje meritev izmeničnih ali enosmernih električnih veličin. Izhodni signal je lahko v obliki analognega enosmernega toka, analogne enosmerne napetosti ali v digitalni obliki. V tem primeru mora biti tisti del pretvornika, ki se uporablja za komunikacijo, združljiv z zunanjim sistemom. Ta standard se uporablja za merjenje pretvornikov, ki se uporabljajo za pretvarjanje električnih veličin, kot so: – tok, – napetost, – delovna moč, – jalova moč, – faktor moči, – fazni kot, – frekvenca, – harmoniki ali skupna harmonska popačenja, – navidezna moč v izhodni signal. Ta standard se ne uporablja za: – instrumentne transformatorje, ki izpolnjujejo zahteve skupine standardov IEC 60044; – oddajnike za uporabo v industrijskih procesih, ki izpolnjujejo zahteve skupine standardov IEC 60770; – naprave za merjenje in nadzorovanje lastnosti/parametrov električnih omrežij (PMD), ki izpolnjujejo zahteve standarda IEC 61557-12. V okviru merilnega razpona je izhodni signal funkcija merjene veličine. Morda je potrebno pomožno napajanje. Ta standard se uporablja: a) če je nazivna frekvenca vhoda/vhodov med 0 Hz in 1500 Hz; b) če je merilni pretvornik del sistema za merjenje neelektrične veličine, se lahko ta standard uporablja za električni merilni pretvornik, če sicer spada na področje uporabe tega standarda; c) za pretvornike, ki se uporabljajo za različne namene, kot sta telemetrija in kontrola procesa, ter v enem od številnih opredeljenih okolij. Ta mednarodni standard je namenjen: – določanju terminologije in opredelitev v zvezi s pretvorniki, ki se uporabljajo predvsem v industriji; – poenotenju preskusnih metod za ocenjevanje lastnosti pretvornika; – opredelitvi mejnih vrednosti točnosti in izhodnih vrednosti za pretvornike.
