Oil Immersed One Load Regulating( OLTC ) Transformer

The on-load regulating transformer applies a new insulating structure and makes short-circuit resistance strong. The iron core is made up of a cold-rolled silicon-steel plate. With the high technology, the on-load regulating transformer is advanced in low coercive force, low loss, good temperature stability, and strong protection for thunder and lighting. Its social benefit is considered that it will save much of electrical consumption and operating cost. all products are qualified by the national mechanical & industrial bureau and national power company. Our on-load regulating transformers are widely used in the power networks, projects, grid construction, etc.

Operation Of Transformer On Load

The load operation of the on-load regulating transformer refers to the working condition of the original winding which is connected to the power supply voltage and the auxiliary winding is connected to the load. At the same time, the secondary side of the on-load regulating transformer also has current distribution. The access circuit of the original transformer will increase correspondingly compared with the no load, and the secondary side voltage will be affected by the load.

How To Choose Your Ideal Transformer On Load

1. be clear about what you are using on-load regulating transformer for, whether you are using it to step up or step down the voltage. Because there are many types of transformers depending on the use.
2. the number of phases of the power supply you are using, single phase or three phase.
3. the cooling method of the on-load regulating transformer according to the environment you are using it in.
4. the material of the coil, copper or aluminum, according to your actual usage and budget.
5. the choice of rated parameters of the on-load regulating transformer. This includes rated voltage, rated current and rated capacity.
