The electrical distribution networks<\/strong> are often the subject of fortuitous faults<\/strong> . In other words, following occasional circumstances, without apparent cause.
\nIt is therefore essential to install protection systems<\/strong> .<\/p>\nMETAL DEPLOYE RESISTOR offers a neutral point resistance range<\/strong> , or earthing resistance (MALT) depending on your electrical needs and your environments ( NER \/ NGR<\/strong> ).<\/p>\n<\/div>

What are the protection systems for electrical distribution networks?<\/h2>\n<\/div>
3 types of \u201cneutral\u201d protection<\/h3>\n
The type of protection depends on the treatment of the neutral line, which can be done via 3 different methods:<\/p>\n
- \n
- Isolated neutral <\/strong> : for small size and low voltage networks<\/li>\n
- Direct earthing of neutral<\/strong> : 20 to 30 times the value of the nominal current<\/li>\n
- Earthing of the neutral line with current limitation<\/strong> default<\/li>\n<\/ol>\n
Advantages of protection with resistance \u201d<\/h3>\n
Only methods using resistance allow:<\/p>\n
- \n
- quick and easy fault detection<\/strong><\/li>\n
- to offer reference potential<\/strong> whose stability is suitable<\/li>\n
- current control<\/strong> artificially created short circuit<\/li>\n
- maximum security<\/strong> for the environment<\/li>\n<\/ul>\n<\/div>
