Product Overview

20 MVA Conservator Substation - 115000V Delta Primary, 13800Y/7968 Grounded Wye Secondary - KNAN, Grey is a product intended for professional commercial and industrial applications.

Key Specifications

• Transformer Features: The industrial transformer features a primary voltage of three-phase 115000V Delta and a secondary voltage of three-phase 13800Y/7968V Grounded Wye. This system is rated for 20 MVA (20,000 KVA). 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 and 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 20 MVA (20,000 KVA). 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-PSTC-R7-3P-DXF-20MVA-GMP-HT-LS-A6-BB-AZ-2Z2-M1 features biodegradable fluid (KNAN). We offer transformers with mineral oil or FR-3 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. Standard liquid level, temperature and pressure/vacuum gauges are analog, manual reading types. These gauges do not have alarm contacts.
• 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 arresters: This system comes with 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.
• Load Breaker Switch: The transformer is equipped with a 2-position load breaker switch.
• Valves: The MT-PSTC-R7-3P-DXF-20MVA-GMP-HT-LS-A6-BB-AZ-2Z2-M1 is equipped with a pressure relief valve, fill valve and drain valve with sampler port.
