Key Specifications

• Transformer Features: The industrial transformer features a primary voltage of three-phase 12470V Delta and a secondary voltage of three-phase 480Y/277 Wye-N. This system is rated for 2.5 MVA (2,500 KVA) [natural cooled] / 3.125 MVA (3,125 KVA) [fan cooled]. We offer systems with loop or radial feed, as well as dead front or live front primary connections. This transformer features a 5-position tap changer with two, +/- 2.5% taps above and two, +/- 2.5% taps below to allow small changes for voltage. There are no rapid rise relays or protection fuses present on the system.
• 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
• Insulation Fluid: The MT-PSTC-R7-3P-DMR-2.5MVA-YE-HT-LS-A6-BBF-CZ-1ZZ-M1 features biodegradable fluid (KNAN/KNAF). We offer transformers with mineral oil or FR-3 fluids, 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, fault indicator, and pressure/vacuum gauges. Standard liquid level, temperature, and pressure/vacuum gauges are analog, manual reading types. These gauges do not have alarm contacts.
• Fault Pressure Devices: There is a Buchholz relay fault indicator on this unit.
• 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 does not come with surge arresters on the primary side.
• Load Break Switch: The transformer is not equipped with a load break switch.
• Valves: The MT-PSTC-R7-3P-DMR-2.5MVA-YE-HT-LS-A6-BBF-CZ-1ZZ-M1 is equipped with a pressure relief valve, fill valve, and drain valve with sampler port.
