introduction of 4600 kVA Inverter Duty Transformer
GNEE TRANSFORMER supplies 4600 kVA Inverter Duty Transformer.
The 4600 kVA Inverter Duty Transformer boasts rugged construction, high overload capability, and low noise and vibration levels. Purpose-built for energy storage applications, it excels under high-frequency and transient load conditions.
The 4600 kVA transformer features a low-voltage double-split structure, with its capacity divided into two equal parts of 2300 kVA each. These segments can operate independently or simultaneously, each connected to a battery pack separately.Double-split transformers facilitate electrical isolation between the two inverters, effectively reducing electromagnetic interference and circulating current between the branches. Furthermore, they ensure that the AC outputs of the inverters are filtered individually, resulting in minimal output current harmonics and enhanced power quality.
Benefits
- Efficient – These devices are built with the latest technology and are designed to handle high loads with relative ease. As a result, it produces less heat and consumes less power compared to conventional transformers.
- Low harmonic distortion – The device is designed to reduce the effects of harmonic distortion which helps in minimising damage to the components of the transformer.
- Sturdy build – The inverter duty transformer is built to withstand high-frequency power voltage. Quite naturally, the materials used to build this device are durable and made by employing the latest technology in the field.
- Compact – The device is usually smaller than conventional transformers, which makes it easier to install and transport as per the customers' requirements.
