Frequently Asked Questions

Three-phase power distribution is essential for industrial applications above 30KVA due to better efficiency, balanced load distribution, cost-effectiveness, and compatibility with industrial machinery. Single-phase systems become impractical and inefficient at higher capacities.

Use our calculator above considering: total connected load, power factor (typically 0.8 for industrial), and we automatically add a 20% safety margin. For motor-heavy applications, starting currents can be 5-7 times the running current.

Air-cooled stabilizers use fans for cooling and are suitable for capacities up to 200KVA. Oil-cooled stabilizers use transformer oil for better heat dissipation, offering higher efficiency and longer lifespan for capacities above 200KVA.

Routine maintenance includes quarterly cleaning of air filters, annual inspection of electrical connections, periodic calibration, and checking of cooling systems. We recommend annual maintenance contracts (AMC) for comprehensive servicing.
