When working with highly technical power systems, you need to be aware of the various integral parts of the power systems. One such important part is the transformer. Transformers or voltage transformers parts of an electrical circuit. These transformers are used to change the voltage of electricity while it is flowing within the circuit. However, understanding a transformer is not enough to make efficient power systems. You need to know the process of spec’ing a transformer. To help you out, here are the steps to the process of spec’ing a power system.
1. Choose the Type
The very first step when spec’ing a transformer is to choose one from different types of transformers as per your need and application. This can be determined by answering some simple questions such as:
- Will you be using high voltage?
- Will you require isolation, rectification or noise attenuation?
- Do you have a furnace available?
- Will you work with pulses?
These questions will help you identify the usage of your power system and which transformer will be best suited for that need.
2. Identify the Voltage
The next step would be to identify the amount of primary and secondary voltages that will be used in the power systems. You can have any range of voltage between 1 to 300,000 volts. In a rare case, if you plan to use only primary voltage, you could go for a ground transformer as it has a grounding instead of a secondary voltage.
3. Determine the Current
After identifying the voltage, you need to determine the current of the secondary voltage. Based on the current of the secondary voltage, you can calculate the power rating of the transformer. Also, determining the current will help you choose a type of transformer.
4. Decide the Frequency
To finally spec the transformer, you need to decide the frequency of the transformer. Deciding the frequency helps to determine the size of the power system and transformer. Generally, frequencies of 50/60 Hz is used commonly for various industrial automation. Also, check for the pulse requirements to build the perfect power system with a transformer.
5. Check the Environment and Operations
Transformers used in the industrial sectors are often placed in locations that are exposed to heat, moisture or other extreme conditions. For such conditions, you need a transformer that does not malfunction. For example, in a highly corrosive location, you will have to consider a transformer with paint and anti-rust applications.
6. Check the Protection and Accessibility
Transformers are electronic devices that can be hazardous if they do not have a proper protection mechanism. When spec’ing a transformer check for corrosion protection, industrial standards non-violation, galvanized radiators, short circuit trip, and alarms, voltage monitors, etc.
If you follow the above-mentioned steps, you will be able to spec your transformer perfectly. If you are one of those who has limited knowledge of working with power systems, do not hesitate to reach out to the engineers of power systems in Edmonton.
