Neutral grounding resistors for energy industry, including natural energy [wind turbines]!
SIMPAX is a valued supplier to the energy industry, supplying market leaders primarily with neutral grounding resistors. Neutral point grounding resistors of the transformer's own needs are used as auxiliary devices in the detection of earth faults in medium voltage main power supply station.
Due to several types of solutions for grounding the transformer neutral point, SIMPAX offer distinguishes the following resistors:
- neutral earthing resistors - connected permanently to the transformer neutral point from one side and to the operating grounding from the other side
- [primary] medium voltage forcing resistors - the transformer neutral point is grounded by the arc-suppression coil, so-called Petersen coil
- [secondary] low voltage forcing resistors - the transformer is also earthed by an arc-suppression coil (so-called Petersen coil), but has a low voltage secondary winding to which the resistor is connected
- AACF [automatic active component forcing] Cabinets - the arc-suppression coil (so-called Petersen coil) has a current transformer whose secondary side is connected to the protective devices
