What is the difference between Delixi voltage regulator SBW and SJW, which is better?
Customer Question:
I am maintaining an uninterruptible power supply and computer server, the whole community shares a transformer, so the voltage fluctuation may be greater during the day and night, there is a period of time when we trip the computer room at night, I see Delixi three-phase voltage regulator has SBW and SJW two models, which one is good, what is the difference between these two voltage regulators?
Engineer answers:
The main difference is that SBW has a compensation coil, SJW does not, for example, it is 380V input, and the output is 380V±4% after voltage stabilization, all the loads of SJW are transformer through the main coil, and the same capacity is more and more bulky, and the heat generation is also greater, so SBW can make the capacity larger and the cost is lower, SJW is mainly used for small and medium-sized capacity of up to 60KVA, and SBW mainly relies on compensation coil boost, coil load search power is not large, So more than 100KVA is very easy to do.
SBW series voltage regulators are mainly used in inductive loads or equipment, such as large loads such as motors and generators. SJW is mainly used in electronic instruments, test equipment, because its voltage requirements are higher, and there are certain requirements for voltage purity, so these two kinds are not good which is bad, mainly depends on where it is used, in this case, it is better to choose a compensating three-phase regulator SBW.

Delixi voltage regulator working principle
In Delixi voltage regulator, the voltage correction from and under voltage conditions is performed through two basic operations, namely Oersted and step-down operation. These operations can be switched on and off manually or automatically by electronic circuits. Under voltage conditions, the voltage of the boost operation is increased to the rated voltage.

Methods for preventing breakdown of transformer insulation
1. Avoid water and air entering the transformer
(1) The transformer should be protected from water ingress and moisture during operation, and it is necessary to seal well the cap of the casing item, the top of the storage phase, the bushing pipe and its connecting pipes. If necessary, a leak detection test should be carried out, and if the insulation has been found to be damp, it should be adopted in time.
