Frequently Asked Questions

A transformer transfers electrical energy between circuits using electromagnetic induction. It steps voltage up or down through two coils (primary and secondary) wrapped around a magnetic core. Changing current in the primary creates a magnetic field that induces voltage in the secondary.
Transformer installation time depends on size, type, and site conditions. Small to medium transformers usually take 1–3 days to install. Large or complex installations may take several days to a few weeks.

Transformers need regular inspection of oil levels, insulation, and cooling systems.
Electrical tests are done to check winding health and insulation strength.
Routine cleaning and tightening of connections help prevent failures.

Yes, transformers are designed to operate 24/7 continuously. They are built to handle constant electrical load under normal conditions. Regular maintenance ensures safe and reliable nonstop operation.
Yes, you can add battery storage to most electrical systems. It stores excess energy for use during outages or peak demand. An energy assessment helps ensure proper sizing and compatibility.
Yes, you can add a transformer to your electrical system. It is used to step voltage up or down to match your equipment needs. A professional assessment is required to ensure safe and proper integration.
