Transformers come in various forms and operate differently, each with specific structure and application-based core and cooling designs. A 15kva transformer price generally varies according to its type. Here's a rundown of the most common types available:
AVR transformers automatically stabilize output voltage by adjusting tap settings on the transformer winding. Their design incorporates additional winding on the same core, creating an auto-tap selection for voltage regulation software. Manufacturers often apply AVRs in regions with unstable voltage supply, ensuring continuous work.
A single-phase transformer has one primary and one secondary winding, while a three-phase transformer has three sets of primary and secondary windings, one for each phase. The three-phase variant is larger and more complex, used for industrial or commercial applications. The single-phase transformer is more compact, rated at 15kVA, and mainly deployed in homes.
Delta/Wye transformers have primary windings connected in a delta configuration and secondary windings in a wye configuration. The delta configuration provides a robust connection among three-phase power systems, while the wye part enables neutral for single-phase loads. This hybrid structure balances the phase currents and enhances system stability, primarily used in complex industrial power setups.
Rotating parts make variable transformers unique by changing the transformer turns ratio. This adjustability allows for fine-tuning voltage output, which is invaluable in laboratories or test environments receiving different voltage needs. Although less commonly applied in permanent power distribution due to moving parts, they're vital for versatility and precision.
As their names imply, a step-up transformer increases input voltage, while a step-down transformer decreases voltage. This goes-up or down through the use of different or the same primary and secondary winding turns. Industries using equipment with voltages different from main supplies often use these transformers.
The rugged 15kVA transformer can power equipment like drills, compressors, and mud pumps in the oil and gas industry. They also serve in offshore and onshore facilities, upgrading and securing reliable voltage for efficient equipment operation in harsh environments. Thanks to their compact designs, they find applications in confined drilling platforms or remote oil fields.
Voltage stabilization and isolation are critical for power-sensitive devices, and aerospace applications often demand ultra-reliable transformers. These transformers also feature anti-vibration designs against extreme flight conditions to ensure continuous safe operation in avionics and satellite systems.
15 kVA isolation transformers are applied in shipboard electrical systems with unique rolling and pitching environmental challenges. They also provide a safety barrier against leakage currents, securing crew and sensitive equipment. Their compactness facilitates installation in constrained ship spaces.
These transformers provide electricity for signaling systems, track switches, and station infrastructure in rail systems. They also endure vibration, humidity, and temperature variations, thus ensuring continuous functioning under such rail conditions. Moreover, they support both AC and DC systems.
In large commercial buildings, transformers power HVAC systems, including chillers, pumps, and compressors, reducing main power distribution voltages to the levels the equipment can safely use. According to the HVAC system's specific voltage requirements and the 15kVA transformer price, businesses can easily get these units to install in their cooling and heating systems.
A 15kVA transformer is often valued for its ideal power handling for small to medium applications. Here are the main features that make these transformers stand out:
The isolation transformer provides galvanic isolation between primary and secondary windings, aiding in separating electrical circuits for voltage stabilization and reducing noise and interference. This feature makes it great for sensitive electronic equipment that requires clean, stable power to function properly.
15kVA transformers use silicon steel laminations as the core material. These laminations decrease energy loss caused by eddy currents during operation. Laminated cores enhance energy efficiency and reduce heat generation, making them ideal for prolonged use.
The 15kVA transformer can handle increased temperatures without overheating. It runs efficiently at higher temperatures, which is critically helpful in settings with high ambient temperatures or heavy load conditions. The ability to run at increased temperatures improves thermal management and extends device life.
These transformers have great cost-performance ratios because they efficiently convert voltages with low energy loss. Their compact structure minimizes material costs, which cuts down on expenses. Furthermore, their efficiency reduces electricity bills and the need for maintenance.
The 15kVA transformer is compact, making it ideal for small and large spaces. Smaller spaces demand high performance in a compact size, and these transformers will achieve that. They'll fit into restricted areas while still delivering great power. Their compactness also allows for easier transportation and installation.
15kVA transformers run cool using air, oil, and water cooling systems. While traditional models use airflow, more advanced versions use oil or even water to reduce rapid heat build-up during heavy loads. These cooling methods allow 15kVA transformers to work efficiently in various ambient temperature conditions.
Selecting a 15kVA transformer requires careful consideration of many factors to ensure it fits the specific requirements and demand of the place of use.
15kVA transformer windings typically use copper and aluminum. Although copper is a better conductor with a smaller footprint and greater efficiency, aluminum is cheaper even with greater length and slightly lower conductivity. When metal prices and space are constrained, choose aluminum. Select copper for efficiency and better performance.
15kVA transformers may need different mounting styles, which may affect their installations. For instance, some models require brackets or a dedicated mounting plate, while others have frame mounts, including vibration absorption. Some models may be mounted on the floor, while others may be more suitable for wall or rack mounting. Consider the mounting style and space availability before purchase.
Consider ambient temperature, humidity, and space conditions before buying. Choose a 15kVA transformer with adequate cooling methods if the environment is too hot or humid, requiring extra cooling. For dusty or wet spaces, choose models with sealed enclosures.
Ensure the 15kVA transformer's input and output voltages match the existing system voltages. If the main power supply is in a three-phase system, a three-phase transformer is ideal. However, if the system is single-phase, a single-phase transformer suffices. For systems with unbalanced loads that require neutral wire, only use Wye-transformers.
15kVA transformers are commonly produced using three popular heating elements: oil-immersed, air-cooled, or water-cooled. Oil-immersed transformers are suited to higher kVA ratings and have better heat regulation and longer duration. Air-cooled transformers are less intrusive and suitable for smaller spaces and lower kVA ratings.

It dissociates input and output currents, lowering surge transient energy from the primary side to the secondary side, protecting sensitive equipment from potential over-voltage.
A2:15kVA transformers have fairly low-maintenance requirements compared to other electrical devices. However, they still require regular inspections and maintenance to ensure their longevity and efficiency. Some of the most crucial maintenance practices include monitoring the cooling systems, inspecting for signs of wear and damage and checking for coolant leaks.
A3:15kVA transformers mostly conform to international standards IEC 60076 and 61558, covering safety, performance, and testing measures. ASTA and UL mark many commercially available transformers, indicating they meet safety requirements for several areas, including industrial and commercial areas.
