Electricity network managers: players at the forefront when it comes to energy needs<\/h1>\n<\/div>

In most developed countries, electricity systems are strongly sollicited nowadays. The complex integration of renewable energies, the development of decentralized means of production and storage, the arrival of \u201csmart grids\u201d, the citizens’ aspiration to energy autonomy and self-consumption, … these are all factors that are at stake in current and future electricity distribution networks.<\/p>\n

Under the effect of the dual digital and ecological transition, there is no shortage of challenges for electricity network operators: production, transmission and distribution.<\/p>\n

As the ordering party for the routing of current to the end customer, the electricity network operators are on the front line. METAL DEPLOYE RESISTOR, acts as a technical partner, faced with requests for the installation of resistors, in France and throughout the world: Earthing resistors, load banks and filtering resistors.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Resistances in response to the demanding needs of electricity network managers<\/h2>\n<\/div>

Within the framework of their constraining environment and their precise specifications, many electricity network operators ask for the installation of resistors.<\/p>\n

There are 3 types of resistors, useful to the electrical distribution sector:<\/p>\n

Earthing resistors – MALT: the safety of installations and people<\/h3>\n

The Earthing resistance ensures repetitive and permanent protection of substations and their components. This avoids costly repairs or replacements.<\/p>\n

In fact, most electrical distribution networks have a neutral connected to the earth in which, in the event of a fault, a very high current would occur. In order to avoid the destruction and disturbances that it could cause, an earth resistance<\/a> is inserted, between neutral and earth, to limit this current and give the protection devices time to act automatically.<\/p>\n

Load resistors – Load bank : test and maintain electrical power<\/h3>\n

To ensure the safety and performance of electrical installations, it is a priority to regularly test existing energy production systems, in order to maintain them and verify their correct operation: generators, turbines, batteries, inverters, etc.<\/p>\n

In the load banks, intended for generating sets, the resistors come into service when the set is operating at low power and prevent the diesel engines from clogging.<\/p>\n

The use of resistors as load banks<\/a> is also customary for the maintenance of accumulator batteries, in electrical laboratories and in telecommunications.<\/p>\n

Filtering resistors: ensuring network interconnections – HVDC<\/h3>\n

The filter resistors<\/a> are integrated in harmonics filters to ensure the interconnections of networks – HVDC and to “clean up” or purify harmonics disturbing the signal – SVC.<\/p>\n

The interconnections of direct current networks, rolling mill trains, and in general, all complex thyristor electrical systems disturb the networks by generations of harmonics. These are eliminated by means of filters comprising high or medium voltage resistors.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

In France and internationally, M\u00c9TAL D\u00c9PLOY\u00c9 RESISTOR works alongside producers, transmitters and distributors of electrical energy.<\/p>\n
