Renewable Energy: Step-up configurations up to 34.5 kV for solar, wind, BESS; FR3 fluid for eco-sensitive sites; remote monitoring ready; tap changer for voltage regulation

Frequently Asked Questions

What kVA rating do I need?

Calculate total load plus 20% growth. General guide: 75-500 kVA for residential (10-50 homes), 500-2500 kVA for commercial, 1000-5000 kVA for industrial or solar farms. Free load analysis available.

Radial vs loop feed - which is better?

Radial is simpler and lower cost. Loop provides dual-source redundancy, allowing maintenance without outage - recommended for critical loads like hospitals, data centers, and malls.

What is the lifespan and maintenance?

30-40 years with routine oil testing, visual inspections, and gauge verification. Annual dielectric testing is recommended.

Are they safe for public areas?

Yes. Lockable enclosures, separate HV/LV compartments, dead-front options, and NEMA 3R weatherproofing meet ANSI safety standards.

Can you customize voltages, fluid, and accessories?

Yes. Any primary up to 34.5 kV, secondary 120-600 V, mineral oil or FR3, radial/loop, and full accessory range (fuses, switches, arresters, shielding, K-factor).

What standards are met?

ANSI C57.12.00/34/90, IEEE, NEMA, DOE, CSA (optional). UL available. Complete factory test reports provided.
