FAQ for voltage regulator
No. Adopting a design of step voltage regulation + induction regulation, it realizes smooth voltage switching. Combined with the buffering characteristics of oil-immersed insulation, it can avoid voltage surges that may impact the power grid and downstream equipment, making it suitable for scenarios requiring high power supply stability.
It mainly requires regular inspection of the insulation oil level and quality (at least once a year), cleaning dust on the radiator surface to ensure heat dissipation efficiency, and monitoring the operation status of the tap changer. These maintenance measures can guarantee the long-term stable operation of the equipment, and professional power operation and maintenance personnel are recommended for the operations.
