Earthing Resistors / Neutral Grounding Resistors
Wärtsilä JOVYLOAD NGR
Grounding resistors consist of the active electrical part (resistor block and control) and the resistor steel casing specially designed for the application (passive part). In principle Wärtsilä JOVYATLAS provides the sheet steel casing for grounding resistors in a galvanised version or in stainless steel on request. Coated grounding resistors can be carried out in the colour of choice. For coating a high performance powder coating on polyester basis is applied. Depending on size and weight the actual grounding resistance is encased in a self-supporting body housing or on a stable base frame.
Wärtsilä JOVYATLAS delivers grounding resistances with the protection class IP00, IP20, IP23 and IP54. All our manufactured grounding resistances of Wärtsilä JOVYATLAS are designed according to the international standards of IEEE-STD 32-1972.
Grounding resistances of Wärtsilä JOVYATLAS are employed worldwide – e.g. our neutral star point grounding resistances are of greatest importance on near shore transformer stations or on offshore platforms with multiple transformers. Numerous companies in the on- and offshore industry trust our technology. We are providing grounding resistances in the range of 12 up to 36 MV, for instance, for the largest German offshore platform „BorWin beta“ and for multiple further platforms.
