A harmonic elimination device can limit the overvoltage caused by ferromagnetic resonance, and can limit the overcurrent flowing through the high voltage transformer when single phase grounding or arc grounding.
The primary harmonic elimination device is composed of a large-capacity non-linear resistor sheet, and has the characteristics of good heat dissipation performance, small volume, large heat capacity, and the like, and can be applied to various voltage transformers.
One harmonic elimination device is connected in series between the neutral point of the PT primary winding of the 6~35KV non-effective grounding system and the ground. When multiple voltage transformers are connected in one system, the three-phase high voltage winding of each transformer should be used. Neutral point is equipped with a harmonic elimination device.
In order to effectively limit the arc grounding overvoltage and eliminate the ferromagnetic resonance.
High Mast Lighting
we provide 30m High mast lighting poles and they are designed to accommodate a number of lowering device manufacturers` equipment. High mast poles can be easily galvanized or painted for even greater versatility.
