Specifications of 12.47kv 480v Transformer 1500 Kva 3 Phase Step Down Loop Feed Pad Mounted Transformer

This 12.47kV to 480V transformer is a 1500 kVA unit. It handles three-phase power. Its main job is stepping down voltage. It takes incoming utility power at 12,470 volts and reduces it to 480 volts. This lower voltage is suitable for commercial buildings, factories, and large facilities needing substantial power.

The transformer uses a loop feed design. This is important for reliability. The loop feed allows power to enter from either direction. It also lets power flow out to other transformers downstream. This creates a more flexible and robust electrical system. Power can often be rerouted if needed. This minimizes downtime during maintenance or faults.

It’s a pad-mounted transformer. The entire unit sits securely on a concrete pad outdoors. Its enclosure is heavy-duty, welded steel. The steel is galvanized. This protects against rust and harsh weather. The enclosure shields all live parts safely inside. This design prevents accidental contact. It keeps people and animals safe. Pad mounting makes installation straightforward. It avoids the need for a dedicated building or vault.

The transformer meets key industry standards. It follows IEEE and ANSI guidelines. This ensures safety, performance, and compatibility. It uses mineral oil for cooling and insulation. The tank is sealed to prevent leaks. Sound levels are kept low. This is crucial near offices or residential areas.

Key technical specifications define its operation. It has a specific BIL rating. This rating shows its ability to handle voltage spikes. Its impedance percentage controls electrical flow under load. Connections are made through accessible bushings. These bushings are designed for easy cable termination. The unit includes reliable pressure relief devices. It has a good temperature monitoring system. It also features a sturdy lifting system. This allows safe handling during installation. Proper grounding points are included for safety. The transformer undergoes thorough testing before leaving the factory. This guarantees it works correctly.

Applications of 12.47kv 480v Transformer 1500 Kva 3 Phase Step Down Loop Feed Pad Mounted Transformer

This 12.47kV to 480V step-down transformer is essential. It handles large power loads safely. It takes incoming medium voltage electricity. It reduces this voltage to 480 volts. This voltage is practical for heavy machinery. The 1500 kVA capacity is significant. It powers big industrial operations effectively. Factories rely on this transformer type. Warehouses need it for lighting and motors. Large commercial buildings use it daily. Data centers depend on its steady power.

The loop feed design is a key feature. It allows power to enter from two directions. This provides a built-in backup path. If one feeder fails, power can reroute. This minimizes downtime dramatically. Critical operations stay online longer. Production lines avoid costly stops. The pad-mounted enclosure is practical. It sits securely on a concrete pad outdoors. This saves valuable indoor space. It protects the transformer from weather reliably. Installation is straightforward. Maintenance access is simple.

The 3-phase power delivery is standard. It matches most industrial equipment needs. Motors run efficiently on three-phase power. This transformer feeds entire sections of a plant. It supports large HVAC systems easily. It powers pumps and compressors without strain. Manufacturing facilities install these units often. They connect directly to the utility feed. They distribute power locally at usable voltage. The robust construction ensures long life. These transformers operate reliably for years. They are a fundamental part of industrial power distribution. Industrial parks utilize them extensively. They are the workhorse for medium-to-low voltage conversion.

5 FAQs of 12.47kv 480v Transformer 1500 Kva 3 Phase Step Down Loop Feed Pad Mounted Transformer

This transformer steps down higher voltage electricity to a safer, usable level. It takes 12,470 volts incoming power. It converts this down to 480 volts outgoing power. Its capacity is 1500 kilovolt-amperes (kVA). This suits large industrial or commercial buildings needing significant power. Three-phase power is standard for heavy equipment.

“Loop feed” means the transformer has two high-voltage connections. Power enters through one connection. Power can also exit through the other connection. This design allows linking multiple transformers together on the same circuit. It provides flexibility for power distribution networks. It helps maintain power if one section fails.

You install this transformer outdoors. It sits on a concrete pad at ground level. Its metal enclosure protects the internal components. The enclosure keeps people safe from electrical parts. It also protects the transformer from weather and animals. Access is needed for maintenance or inspection.

Safety is critical. The enclosure is locked and tamper-resistant. Warning labels are clearly visible. Internal components are insulated. Grounding connections prevent dangerous voltage build-up. Pressure relief devices protect against internal faults. Proper installation following electrical codes is essential.

Regular maintenance is vital for long life. Visual inspections check for damage, leaks, or corrosion. Connections need tightening periodically. Dielectric fluid levels and condition must be checked. Oil samples are tested for contamination. Bushings and arresters need inspection. Professional technicians should perform detailed checks.
