مشخصات:
Neutral Grounding Resistors limit fault current to ensure safety of workers and equipment in electrical systems.
The purpose of this application;
• Maximizing operational continuity and safety by limiting the ground short-circuit current to levels that will not damage the transformer and generator.
• Thanks to the Current Transformer in the Neutral Grounding Resistor, the fault is detected by the relays and the fault duration is defined.
• Limiting the oscillating and non-oscillating transient voltage fluctuations that will occur with the interruption of the fault current, thus protecting the isolation levels of the equipment in the system.
• Increasing personnel safety by ensuring that the step voltage in the field is kept at reliable levels
• Prevention of overheating and mechanical stress of all equipment exposed to fault current
The failure time is usually chosen as 5-10 seconds. This period can be up to 30 seconds in businesses that cannot tolerate sudden power cuts. In fact, in facilities such as hospitals, data centers, textile, cement and injection molding factories, the continuity of the system is very important and the fault time can be selected continuously, provided that the fault current is at a level that will not damage the system in order to detect the fault point without power interruption.
