Transformer Features: With a transformer rating of 1500 KVA (1.5 MVA), the industrial transformer features a primary voltage of three-phase 12470ÊDeltaÊand a secondary voltage of three-phase 480V. The unit has a primary loop feed for single installations and dead-front primary connections. We also offer systems with radial feed and live front primary connections. There are no tap changers, rapid rise relays and surge arrestors present on the system.

Aluminum transformer winding material helps improve performance, reduce weight and lower cost. Compared to copper, aluminum windings have lower eddy losses due to higher resistivity. This transformer consists of rectangular coil and five-legged wound core design with three coils and four core loops (this is for three-phase transformers only; single-phase units have one coil and two core loops).

The MT-PML-R2-3P-DMR-1.5MVA-DE-LT-DF-A6-CB-AZ-2B4-M2Êis air cooled and does not have fans or mounting provision for fans.

Temperature Rise: This unit features a 55¡C/65¡C temperature rise for reduced heat waste, increased reliability and longer life. At 55¡C temperature rise, the system offers 1500 KVA (1.5 MVA) capacity and runs the transformer cooler. At 65¡C temperature rise, the transformer offers 1680 KVA (1.68 MVA) for an extra 12% capacity and runs the unit hotter. The transformer meets standard efficiency requirements (does not meet DOE 2016 efficiency standards). The combination of low temperature rise and high efficiency makes this unit suitable for use in electrical rooms, air conditioned spaces in buildings, underground vaults and similar locations, in addition to outdoor areas.

Insulation Fluid: The MT-PML-R2-3P-DMR-1.5MVA-DE-LT-DF-A6-CB-AZ-2B4-M2Êfeatures biodegradable cooling fluid (KNAN) with a capacity of 410 gallons. We offer transformers with FR-3 oil fluid, if needed.

Biodegradable Fluid: Biodegradable cooling fluid (vegetable oil) has a higher heat capacity compared to mineral oil, making the liquid safer to use and more reliable during operations. Vegetable oil has a higher flash point and fire point than mineral oil, hydrocarbon oil, silicone oil and synthetic ester. This cooling fluid is also non-toxic and can tolerate higher breakdown voltages than mineral oil. When operating at high temperatures, biodegradable cooling liquid sustains up to 120% loan conditions, which helps preserve the transformer's lifespan and performance.

Gauges: The following gauges are included with the system: liquid level, temperature and pressure/vacuum gauges. These liquid level, temperature and pressure/vacuum gauges are analog, manual reading types with auxiliary contacts for remote monitoring or alarms.

Fault Pressure Devices: There are no fault pressure devices on the unit. Fault pressure devices are used to detect high rates of pressure rise within the tank.

Rapid Rise Relay: There are no rapid rise relays on the unit. This safety component is designed for protection when a rapid increase in tank pressure occurs. The relay is suitable for detecting sudden pressure fluctuations above predetermined safe limits.

Surge Arrestors: There are no surge arrestors on the unit. We can offer systems with mounting provisions for surge arrestors. Transformers with external surge arrestors offer protection from lightning strikes, surges or transient voltages and switching surge.

Load Breaker Switch: The transformer is equipped with a load break switch. This switch has four positions: A side on + transformer on, B side on + transformer on, A and B sides + transformer on, and A and B sides + transformer off.

Valves: The MT-PML-R2-3P-DMR-1.5MVA-DE-LT-DF-A6-CB-AZ-2B4-M2Êis equipped with an automatic pressure relief valve, fill valve and drain valve with sampler port.

Protection Fuses: This transformer has bayonet protection fuses on the primary side. For units without protection fuses, up stream protection is provided. We recommend provisions for protection fuses when possible, as blown fuses may require more frequent oil changes.

Mount: The heavy-duty enclosure makes the unit suitable for both indoor and outdoor applications. This power distribution system can be pad mounted on concrete pads.

Benefits: The MT-PML-R2-3P-DMR-1.5MVA-DE-LT-DF-A6-CB-AZ-2B4-M2Êpad mount transformer offers many benefits to consumers. This transformer provides owners with significant energy savings, as well as offering environmental benefits. Higher efficiency not only extends the life of the transformer, but also turns into cost savings for owners in the form of lower energy bills and decreased cost of ownership.

Applications: General purposes, industrial sites, electrical rooms, underground vaults, manufacturing facilities, steel plants, offshore, commercial, military, processing plants, electric power distribution, utilities, public locations and more.

Larson Electronics is a manufacturer and as such can build stationary and portable transformer systems to your specifications. Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our prebuilt units.
