1 MVA Pad Mount Transformer - 12470Y/7200 Grounded Wye Primary, 208Y/120 Wye Secondary

1 MVA Pad Mount Transformer - 12470Y/7200 Grounded Wye Primary, 208Y/120 Wye Secondary - KNAN/Bell Green https://www.larsonelectronics.com/product/287900/1-mva-pad-mount-transformer-12470y-7200-grounded-wye-primary-208y-120-wye-secondary-knan-bell-green?productIdBase64=Mjg3OTAw0&rank=78 Transformer Features: With a transformer rating of 1000 KVA (1 MVA), the industrial transformer features a dual rated primary voltage of three-phase 12470Y/7200 grounded Wye and a secondary voltage of three-phase 208Y/120 V Wye. An input voltage switch allows the transformer to be switched between primary voltages. copper transformer winding material helps improve performance, reduce weight and lower cost. Compared to copper, copper 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-R7-3P-GMR-1MVA-YT-LT-DF-A6-BB-CZ-2B6-M1 is air cooled and does not have fans or mounting provision for fans. Temperature Rise: This unit features 65°C temperature rise for reduced heat waste, increased reliability and longer life. At 65°C temperature rise, the transformer offers 1000 KVA (1 MVA). The transformer meets standard efficiency requirements. 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-R7-3P-GMR-1MVA-YT-LT-DF-A6-BB-CZ-2B6-M1 features biodegradable cooling fluid (KNAN) with a capacity of 350 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. Gauges: The following gauges are included with the system: liquid level, temperature and pressure/vacuum gauges. Standard liquid level, temperature and pressure/vacuum gauges are analog, manual reading types. These gauges do not have auxiliary contacts. Fault Pressure Devices: This transformer features an automatic action fault pressure device. 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 arresters: This system comes with high elbow surge arresters on the primary side. Designed for over-voltage and transient voltage protection, the components prevent damage caused by lightning, internal switching or voltage surges. We can offer models without high elbow surge arresters that have mounting provisions for customer-provided surge arresters. Valves: The MT-PML-R7-3P-GMR-1MVA-YT-LT-DF-A6-BB-CZ-2B6-M1 is equipped with a pressure relief valve, fill valve, and drain valve with sampler port. Protection Fuses: This transformer does not contain protection fuses. 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-R7-3P-GMR-1MVA-YT-LT-DF-A6-BB-CZ-2B6-M1 pad 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.
