MINGRUI resistors are designed to absorb a large amount of energy without exceeding temperature limitations defined in IEEE32. Neutral Grounding Resistors MINGRUI manufacture can be used for indoor and outdoor and the neutral point is connected with a porcelain bushing or with a high voltage cable from the bottom, top or side. The most common protection degree preferred for Neutral grounding resistors is IP23 as it allows the resistor elements to cool easier and they can be used both at sea shores and deserts because the resistor elements are completely stainless steel and does not affected by extreme conditions. Neutral grounding resistors are shipped with maintenance and installation guide, in which, recommended relay settings for each Neutral grounding resistor are stated as well. MINGRUI provides complete technical assistance in order to meet your specifications or site conditions.
