Transformer Features
This power transformer, rated at 500 KVA, features a primary voltage of three-phase 27600V Delta and a secondary voltage of three-phase 480GrdY/277V. It includes a 5-position tap changer. The high and low-voltage bushings have a side-mounted design with an air terminal chamber. The size of the air terminal chamber is customized according to customer requirements. Bushing location and phase rotation were coordinated with primary and secondary switchgear to provide correct alignment when the switchgear and transformer are connected in the field.
Copper winding material enhances short-circuit resistance, offering high reliability, mechanical strength, and a compact size compared to aluminum. The transformer features a three-legged core construction and is air-cooled without fans or mounting provisions.

Insulation Fluid
The 500 kVA power transformer features degradable vegetable oil cooling fluid (KNAN) with a capacity of 145 gallons. It is environmentally friendly and can improve the transformer's insulation and extend its service life. If needed, Daelim Transformer offers FR3 vegetable and mineral oil that meet ASTM standards.
Gauges
The system includes a liquid level indicator, thermometer, pressure relief device, vacuum pressure gauge, and winding temperature indicator gauges with auxiliary contacts for alarm and trip functions. Not only can the operating status of the transformer be remotely monitored, but it also facilitates inspection and maintenance. These instruments are in the instrument box and can be waterproof, sunproof, and dustproof. We can provide auxiliary contacts according to customer requirements for alarms, trips, faults, etc.
Lightning Arresters
Lightning arresters on the primary side provide over-voltage and transient voltage protection against lightning, internal switching, or voltage surges. These lightning arresters are designed to intercept and divert excessive voltage spikes away from the primary winding of the transformer, thereby preventing them from reaching sensitive electrical equipment connected to the system. By effectively dissipating the energy generated by lightning strikes or voltage surges, the arresters ensure the protection and integrity of the transformer. We can provide arrester models according to customer installation requirements.
Valves
Complete with essential features for optimal operation, including a pressure relief valve to release excess pressure, a fill valve for maintaining proper fluid levels, a drain valve equipped with a sampler port for easy fluid sampling, and a nitrogen blanket featuring a purge valve to ensure a controlled atmosphere within the transformer. All these valves have protective covers to avoid erosion by rain, dust, etc.
Mount
Since all instruments, valves, and high and low-voltage bushings of this transformer are protected by covers, it is suitable for outdoor applications.
Benefits
The S-500-27.6-0.48 three-phase power transformer offers many benefits to consumers. With cUL certification, it is safe and reliable. Meets or exceeds CSA efficiency value standards, improving energy efficiency, and thereby reducing power consumption and operating costs. Its environmentally friendly design greatly reduces carbon dioxide emissions and contributes to the establishment of an ecological energy system. Instrumentation with auxiliary contacts significantly reduces maintenance costs.
