SIST EN 61243-3:2015

Live working - Voltage detectors -- Part 3: Two-pole low-voltage type

This part of IEC 61243 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: – for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2 3 Hz and up to 500 Hz, and/or
– for d.c. voltages not exceeding 1 500 V.
NOTE The a.c. voltages defined in this standard refer either to phase-to-phase voltages or phase to neutral voltages.
Contact electrode extensions are not covered by this standard. Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions. Voltage detectors covered by this standard are not intended to be used for continuous operation.
Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level.
This standard also includes provisions for the following supplementary functions when available (see Annex B):
– phase indication,
– rotating field indication, and
– continuity check.
Other supplementary functions are not covered by this standard. Voltage detectors covered by this standard are not considered as measuring devices. Relevant safety requirements for measuring devices are included in IEC 61010 series.

Arbeiten unter Spannung - Spannungsprüfer -- Teil 3: Zweipoliger Spannungsprüfer für Niederspannungsnetze

Travaux sous tension - Détecteurs de tension -- Partie 3: Type bipolaire basse tension

L'IEC 61243-3:2014 concerne les détecteurs de tension portatifs bipolaires ainsi que leurs accessoires (les pinces crocodiles et les cordons détachables) pour un usage au contact avec des pièces d'installations électriques à des tensions alternatives n'excédant pas 1 000 V à des fréquences nominales comprises entre 16 2/3 Hz et 500 Hz, et/ou à des tensions continues n'excédant pas 1 500 V. Les rallonges d'électrode de contact ne sont pas couvertes par la présente norme. Les détecteurs de tension couverts par la présente norme sont prévus pour une utilisation sous des conditions sèches et humides, à l'intérieur et à l'extérieur. Ils ne sont pas prévus pour une utilisation en conditions de pluie. Les détecteurs de tension couverts par la présente norme ne sont pas prévus pour un fonctionnement en continu. Les détecteurs de tension couverts par la présente norme sont prévus pour une utilisation à une altitude allant jusqu'à 2 000 m au-dessus du niveau de la mer. La présente norme inclut aussi des dispositions pour les fonctions supplémentaires suivantes, lorsqu'elles existent:
- l'indication de phase;
- l'indication de la rotation de phase;
- et le contrôle de continuité. Les autres fonctions supplémentaires ne sont pas couvertes par la présente norme. Les détecteurs de tension couverts par la présente norme ne sont pas considérés comme des instruments de mesure. Les exigences de sécurité relatives aux instruments de mesure sont incluses dans la série de normes IEC 61010. Cette troisième édition annule et remplace la deuxième édition publiée en 2009. Elle constitue une révision technique qui inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- exigence et essai pour la gestion des tensions perturbatrices aux fréquences industrielles;
- et l'annexe informative sur les détecteurs de tension et présence de tension perturbatrices.

Delo pod napetostjo - Indikatorji napetosti - 3. del: Dvopolni nizkonapetostni tip (IEC 61243-3:2014)

Ta del standarda IEC 61243 velja za ročne dvopolne nizkonapetostne detektorje napetosti z dodatno opremo (krokodilske sponke in odstranljivi vodi), ki se uporabljajo pri stiku z deli električnih sistemov: – za izmenični tok z napetostjo, ki ne presega 1000 V pri nominalnih frekvencah med 16 2 3 Hz in do 500 Hz in/ali
– za enosmerni tok z napetostjo, ki ne presega 1500 V.
OPOMBA Izmenični tokovi z napetostmi, določenimi v tem standardu, se nanašajo na medfazne ali fazne napetosti.
Ta standard ne zajema podaljškov kontaktnih elektrod. Detektorji napetosti, ki jih zajema ta standard, so namenjeni za uporabo v suhih in vlažnih pogojih v zaprtih prostorih ter na prostem. Niso namenjeni uporabi v dežju. Detektorji napetosti, ki jih zajema ta standard, niso namenjeni neprekinjenemu delovanju.
Detektorji napetosti, ki jih zajema ta standard, so namenjeni za uporabo do nadmorske višine 2000 m.
Ta standard zajema tudi določbe za naslednje dodatne funkcije, kadar so te na voljo (glej dodatek B):
– navedba faze,
– navedba vrtilnega polja in
– preverjanje zveznosti.
Standard ne zajema drugih dodatnih funkcij. Detektorji napetosti, ki jih zajema ta standard, se ne obravnavajo kot merilne naprave. Ustrezne varnostne zahteve za merilne naprave so zajete v skupini standardov IEC 61010.
