5.16.1 Które pomiary izolacji naley wykona? 5.16.1 Which insulation measurements have to be peformed?

Norma DIN VDE 0100 cz 610 okrela pomiary izolacji pomidzy

przewodnikami w rozdziale 5.3.

Jeeli obwód zawiera aparaty elektryczne jak

półprzewodniki, elementy te ze wzgldu na

delikatno nie powinny by naraone na wysokie

napicie.

DIN VDE 0100 part 610 specifies insulation measurement between

the conductors in Section 5.3:

If the circuits contain electronic components,

such as semiconductors, these sensitive components

must by no means be damaged by the

high measuring voltages.

Pomiary mog by take wykonywane z włczonymi odbiorami. Jeli

rezystancja izolacji jest za niska, naley wówczas rozłczy odbiorniki

i dokona pomiarów systemu i odbiorników oddzielnie.

.

Po instalacji rozdzielnicy naley dokona pomiaru nastpujcych

obwodów:

• Wszystkie linie pomidzy aparatami ochronnymi.

• Lini za ostatnim zabezpieczeniem nadprdowym bez połczenia

z odbiornikami.

Measurement may also be performed with the consuming equipment

connected. If the insulation resistance is too low in this case,

the consuming equipment must be isolated, and the system and

consumer must be measured separately.

Prior to commissioning, the following circuits must be measured:

• All line sections between any 2 overcurrent protection devices.

• The section following the last overcurrent protection device

without any connected consumer equipment.
