Guide to Pick the Right Power Transformer
Transformers are a fundamental part of all major electrical power distribution systems today. The constant growth in the demand for power has forced operators to seek modern 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 production of transformers is the key to consistent industrial growth. Identifying the need and the supplies in demand of these devices, several power transformer manufacturers have come up in and around the area.
Despite this, owing to their operational vitality, it is very critical to ensure that you choose the best electrical power transformer. Prior you begin your search for good power transformers in Canada, below are a few factors you must consider carefully:
Transformer Operational Area
The environment in which the transformer will operate should be a deciding factor while searching for a transformer.
For example, if they are to be located near the sea-shore, the salty air could be corrosive.
In such a case, you’ll require transformers that are well laminated so that they don’t suffer losses.
Thus, examine the effect of moisture and temperature on transformers too and make sure that the machine is appropriately equipped to deal with the ill effects of both.
Identify 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 conditions, find out which loads would be running at the same time.
Would there by a chance of running the Air Conditioner and the Electric Heater at the same time depending on areas? Are there other pieces of equipment that 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.
Know which Specifications are Needed?
When selecting a power transformer, ensure that it has exact specifications that match your requirements. To begin with, answer the following questions:
- Do you require a pole-mounted, a pad-mounted, a vaulted, or a caged transformer?
- Does it require a 3-wire, a 4-wire, or a 5-wire configuration?
- Have you checked the impedance?
- Do you need 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;
- pressure relief device
- liquid level gauge
- lightning arrestors
- grounding resistors
- 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.
Provides Protection
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.
