Tips for Installing Transformers

Transformer InstallationTaking safety precautions and following best practices is critical when installing a transformer onsite. It all begins with purchasing high quality products. Ensure that you partner with reliable single or 3 phase transformer manufacturers that adhere to strict quality standards.

Here are some more tips to ensure that your transformer gets installed smoothly and gives you several years of service.

Strictly Adhere to Manufacturer Guidelines

A transformer can be installed in several ways, depending on the purpose. For example, you may want to install it at ground level; on a concrete pad; or outside, inside or on top of a facility. You need to be aware of, and implement, safety precautions as specified by the manufacturer for each type of installation.

Ground installation, for instance, would require you to study the soil type beforehand to assess its suitability to accommodate the transformer. Installing a transformer without this preliminary study can lead to equipment damage, poor performance, and weak and risky electrical connections.

Similarly, be sure to study the structural strength of the facility if you intend to install the transformer inside the premises. If the facility is in a seismic region, precautionary steps must be taken to ensure that the equipment doesn’t result in loss of life during earthquakes.

Inspect Transformer Immediately after Delivery

Check for obvious damages that could be caused due to transportation or negligent handling. File a complaint with the transportation company if you encounter signs of equipment mishandling. Inform the manufacturer about the damage simultaneously.

After this initial inspection, remove the external cover to examine the unit from inside. Check for damage such as broken parts, and loose connections. Be sure to also check for contaminants like water, dirt and moisture.

If the transformer is not going to be installed immediately, perform another round of the above inspection, just before installation.

Considering the above risks, it is important to choose reputed single and 3 phase transformer manufacturers, dealers and transportation experts.

Check Transformer Sound Level
A power transformer’s core generates sound of at least 120Hz level (think of live music in a disco). In some units, the sound could be way higher.

Depending on the surroundings, the sound may be audible or could go unnoticed. For example, in a quiet room, the sound is more pronounced than in a location with multiple equipments like motors and compressors.

Some applications demand absolute silence in which case a sound-reduction system corresponding to the frequency generated can be installed.

Follow Essential Precautions before Setting the Transformer Live

Ensure that grounding is in place. Grounding eliminates static charges, if any. It also protects against risks such as an accidental contact between transformer winding and its core.

Follow protection requirements specified by the manufacturer if aluminium conductors are involved.

Employ only qualified technicians with experience in handling high-voltage equipment to install conductors.

Do not install washers between bus bar and terminal lug. This presents the risk of connection overheating.

Adhere to space requirements specified by manufacturers for installing cables. Do not install them adjacent to coils or blades.

Ensure that there are no breaks or gaps in windings.

Perform an insulation resistance test to assess transformer’s capability to accept applied voltage.

Conduct a final inspection of the transformer before sending it live. Inform all people involved in transformer installation before energizing the unit.
