If you are thinking to purchase an unmatched quality transformer then there are two primary concerns such as load as well as application. Numerous aspects must be evaluated precisely while making the choice, to make sure that the requirements of both primary concerns are met. The cost, as well as capacity of the transformers generally relate to a set of evaluation factors such as:
- Selection of Winding Material
For ensuring the longer working life or excellent functionality, the offered transformers use copper or aluminium material for windings. These winding materials are better conductors. The copper contributes to the stronger mechanical strength of the coil.
- Use of Low-Loss Core Material
The selection of core is also the most important factor that influences the purchasing decision. Losses that arise in the core are because of the hysteresis as well as eddy currents. Finest quality magnetic steel should be utilized so that hysteresis losses are decreased; laminated cores are chosen to reduce eddy current losses.
- Protection from Harsh Conditions
It is also most important that transformer core, coils, leads and complete accessories are properly protected from several harsh conditions. The sealed-type design of the liquid-filled transformers provides proper protection to the internal components against a large number of hazardous environment conditions.
It is also an essential thing to be considered while purchasing transformers. The difference between the secondary’s no-load voltage and full-load voltage is a measure of the transformer’s regulation. Poor regulation implies that as the load increases, the voltage at the secondary terminals decreases considerably.
- Voltage Taps
If the regulation is good, then the secondary voltage of a transformer can transform and even the coming voltage changes. Transformers are joined to a utility system as well as dependent upon utility voltage. While utility operations vary or new loads are linked to their lines, the coming voltage to your facility may decrease, or even maybe increase.
Operating conditions can sometimes require overloading of a transformer. When the transformer is not able to withstand extra load it is called overloading condition. The customer can easily purchase these systems according to the power capacity that they want.
A transformer’s ability to reduce electrical noise as well as interims an important consideration, specifically when concerning with specific types of load. The application of a shield between the primary and secondary coils of a distribution transformer is regularly accomplished when solid state equipment is being served.
So, if you are making a plan for purchasing transformers then these evaluation factors are very helpful for you.
