FAQs – Isolation Transformer 15 KVA
What is a 15 kVA isolation transformer?
A 15 kVA isolation transformer is an electrical device rated at 15 kilovolt‑amperes (kVA) which provides galvanic isolation between its primary and secondary windings. It delivers the required output voltage while isolating the load from the supply network, reducing electrical noise, ground‑loop interference and enhancing safety.
Where should a 15 kVA isolation transformer be used?
This transformer is ideal for small industrial machines, sensitive equipment, medical labs, IT/data‑centre rooms, control panels, and in applications where stable supply and isolation from supply disturbances is required.
What are the key features of a 15 kVA isolation transformer?
Key features include: true isolation (separate primary & secondary windings), rated capacity 15 kVA, robust core and winding construction, low leakage current, low electrical noise, protection against surges and spikes, and often compliance with relevant safety standards.
How should a 15 kVA isolation transformer be installed and maintained?
Installation requires proper ventilation, correct voltage matching (input & output), correct phase/connections, and grounding of the enclosure. Maintenance includes periodic inspection of connections, checking for overheating, ensuring insulation resistance is within limits, cleaning dust, and avoiding overloading to ensure long service life.
Can a 15 kVA isolation transformer be overloaded or used at higher loads?
No. A 15 kVA transformer is rated for its maximum continuous load. Overloading can cause excessive heating, increased losses, reduced lifespan, insulation damage and potential failure. Always operate within or below its rated capacity and account for inrush currents and power factor when selecting size.
