The transformers automatic voltage booster and precise tapping range (2x2.5%) allow seamless voltage regulation during fluctuating loads. Overload capacity up to 120% for short durations ensures resilience during peak utility demands. Surface treatment and weatherproofing provide long-term reliability for outdoor installations.

Safe and Flexible Operation

With porcelain bushings, pad-mounted channels, and weatherproof tamper-resistant construction, this transformer prioritizes safety. Earthing terminals on both high voltage and low voltage sides, along with silent operation (below 55 dB at 1 meter), make it suitable for varied locations, including urban and industrial power distribution networks.

FAQs of 500 kVA Electrical Power Transformer:

Q: How do I install the 500 kVA electrical power transformer for optimal safety?

A: The transformer should be installed on a secure, level pad using the supplied mounting base channels. Earthing terminals for both high and low voltage sides must be properly connected, and the weatherproof, tamper-resistant enclosure helps safeguard it against outdoor elements. Adhere to electrical standards and consult a licensed professional for installation.

Q: What is the typical usage of this 500 kVA transformer in power distribution networks?

A: This transformer is primarily used in medium- to large-scale electrical power distribution, converting voltage from 11 kV to 433 V across industrial, commercial, and utility networks. Its high efficiency and robust design ensure consistent performance in diverse environments, making it ideal for substations, manufacturing plants, and large commercial facilities.

Q: Where can this transformer operate reliably with respect to environmental conditions?

A: With a weatherproof enclosure, epoxy paint corrosion protection, and tolerance for up to 95% humidity at 40C, the transformer is designed for reliable operation both indoors and outdoors, even in tropical or industrially challenging areas across India.

Q: What makes the cooling system of this transformer effective?

A: The transformer utilizes an ONAN (Oil Natural Air Natural) cooling system with approximately 580 liters of cooling oil. This system allows efficient heat dissipation during continuous operation, maintaining safe temperature levels (-25C to 50C) and enhancing transformer longevity.

Q: When should I use the tapping range feature on the HV side?

A: The 2x2.5% tapping range is utilized during instances of fluctuating supply voltages to regulate and maintain a steady output. Adjustments should be made when persistent voltage variations are detected in the electrical network, ensuring consistency for sensitive equipment and overall grid stability.

Q: How does this transformer benefit my power distribution system?

A: With high efficiency (98%), low noise output, support for momentary overloads up to 120%, and superior build quality, this transformer reduces energy losses, lowers operational costs, and ensures reliable service. Its automatic voltage booster and secure design further safeguard power distribution infrastructure.
