A Guide to Pick out the Best Power Transformer
Transformers are an integral part of all major electrical distribution systems today. The continuous growth in the demand of power has forced operators to seek transformers which can be used for a variety of functions. These may range from transferring energy between circuits and stepping up/down alternating voltages to reducing line losses.
The efficient and reliable performance of transformers is the key to consistent industrial growth. Sensing the need and the burgeoning demand of these devices, a number of power transformer manufacturers have come up in and around the area. However, owing to their operational vitality, it is extremely important to ensure that you choose the best electrical power transformer.
So, before if you are searching for good power transformers in Canada, here are a few factors you must carefully consider:
Where will the Transformer Operate?
The environment in which the transformer will operate should be a deciding factor while searching for a transformer. For instance, if they are to be located near the sea, the salty air could be corrosive. In this case, you require transformers which are properly laminated so that they don’t suffer losses. Similarly, observe the effect of moisture and temperature on transformers too and make sure that the machine is adequately equipped to deal with the ill effects of both.
What is the Maximum Coincident Load?
The key to the efficient running of a transformer lies in understanding what its maximum coincident load would be. This basically is the largest amount of load you can expect the transformer to supply. Based on your operational requirements, find out which loads would be running at the same time.
Would you be running the air conditioner and the electric heater together? Are there other pieces of equipment which might be employed simultaneously?
Once this has been determined, calculate the kVA rating. Sum up these individual calculations and then add 20% to account for contingency. Pick a transformer capable of handling the calculated load requirement.
What other Specifications are Required?
When choosing a power transformer, make sure that it has the precise specifications which match your requirements. To begin with, answer the following questions:
- Do you want a pole-mounted, a pad-mounted, a vaulted, or a caged transformer?
- Does it need a 3-wire, a 4-wire, or a 5-wire configuration?
- Have you checked the impedance?
- Do you require a dry-type or a liquid-filled transformer?
- What is the transformer’s basic impulse/insulation level?
Once you know these, compare them with your operational needs and select the one that best suits your needs.
Which Accessories will you need?
Depending on its use, you will have to supplement your transformer with a few indispensable accessories. These include a pressure relief device, a liquid level gauge, lightning arrestors, grounding resistors, and a Basler relay. Apart from these, you might also consider using a sudden pressure relay, a winding temperature gauge, and a vacuum gauge. These accessories are meant to ensure that your transformer continues to function with efficiency.
Are they Protected Sufficiently?
Though most transformer manufacturers offer a plethora of safeguards, it is still wise to manually check them before the purchase. Look specifically for hot-dipped galvanized radiators, trip functions for temperature control, alarm functions for pressure variations and oil level monitors. Moreover, make certain that it doesn’t just meet the industry standards but it also follows the regulations prescribed by federal authorities.
