Neutral Earthing Resistors
Leistung Energie - Neutral Earthing Resistors
Advantages:
• Easy access and maintenance
• High insulation and mechanical strength against impacts
• High internal insulation and high mechanical resistance against to shocks and sagging thanks to the use of large surface satiated bushings and M16 shear connectors
• Special grid resistance design to prevent point overheating
Application Areas:
• In power generators used in Power Generation Plants such as Thermal, Nuclear, Gas, Hydroelectric and Wind Power Plants
• Step-up transformers used in Power Generation Plants such as Thermal, Nuclear, Gas, Hydroelectric and Wind Power Plants
• In step-down transformers terminating energy transmission lines
• Transformers and generators used in cogeneration and trigeneration systems in large facilities such as factories, hospitals, shopping centers
