As an important power equipment, three-phase compensating power regulators play a vital role in the power system. It can maintain the stability of the system voltage by automatically adjusting the output voltage of the power supply, so as to ensure the normal operation of electrical equipment. However, proper wiring installation is also critical for the proper functioning of a three-phase compensated power regulator. In this paper, the wiring method and effect of the three-phase compensating power regulator will be analyzed.
There are three types of wiring for three-phase compensated power regulators: star-linked, delta-connected and star-delta connection.
A star connection is to connect each phase of the regulator to each phase of the power supply in turn, and connect the neutrals of the three phases at the same time. The advantage is load balancing, which is suitable for occasions with large load fluctuations, but the wiring is complex and requires three conductors and three core cables. 
A triangle connection connects each phase of the regulator in turn to form a loop. The advantage is that the wiring is simple and convenient, only three wires are required, but special design is required when the load is unbalanced.
A star-delta connection is a combination of a star-shaped connection and a delta connection by connecting one winding to the neutral point at the power supply end and the other end to the load side of the regulator. This can effectively improve stability and adapt to different load situations.
We will analyze the effect of different wiring methods on three-phase compensated power regulators.
The first is the star connection. Since the star connection can achieve load balancing, the star connection can better keep the voltage stable in the case of large load fluctuations. In addition, the star connection reduces the short-circuit current to the power supply and increases the life of the regulator. However, since the star connection requires a separate neutral, it increases the difficulty of installation and maintenance.
This is followed by a triangular connection. The advantage of the delta connection is that it is easy to wiring and can be adapted to load imbalances. However, when the load fluctuates greatly, the delta connection cannot be load balanced, which can lead to a decrease in stability. In addition, since there is no need for a separate neutral wire, the triangular connection allows for more economical and efficient power delivery.
Finally, there is the star-triangle connection. The star-delta connection not only has the load balancing capability of the star connection, but also can adapt to the load imbalance. This wiring improves the stability of the regulator and makes it suitable for a wide range of load situations. However, the star-delta connection requires additional wiring, increasing the complexity and cost of the power system.
The wiring method of the three-phase compensating power regulator has an important impact on its effectiveness. Choosing the appropriate wiring method according to the actual situation can improve the stability and adaptability of the voltage regulator. Whether it is a star-shaped connection, a triangular connection or a star-delta connection, it has its applicable occasions and advantages. When wiring is installed, please choose according to the load situation and actual needs, and make sure that the wiring is correct to ensure the normal operation of the equipment.
