3000 kVA Substation Transformer
The SL-3000/11/0.415 transformer is a 3-phase substation transformer designed for use in Australia and conforms to the AS/NZS 60076, IEC60076-1, and IEC60076-3 standards. These standards ensure that the transformer meets the necessary safety and performance requirements for the Australian market.
The transformer has a primary voltage of 11000V and a secondary voltage of 415V, which are typical voltage levels for distribution transformers in Australia.
The high-voltage bushing of the transformer is of the dead-front type, which means that it is designed to be fully enclosed and insulated, minimizing the risk of accidental contact with live parts.
The transformer features a terminal box for connecting indicators and gauges. This box allows for convenient monitoring and measurement of various parameters during operation.
To adhere to Australian standards, the transformer utilizes capital and small letters A(a), B(b), and C(c) markings for high and low voltage phases, and the grounding terminal is marked with N(n) to indicate the neutral connection.

The S-3000-3990/44-0.6 transformer is designed and produced according to CSA standards specifically for the Canadian market.
The transformer has a high voltage (HV) rating of 44kV, which represents the primary voltage level. The low voltage (LV) rating is 600V, representing the secondary voltage level.
The power rating of the transformer is specified as 3000kVA for KNAN (Kilovolt-Ampere Natural Air Natural) cooling and 3900kVA for ONAF (Oil Natural Air Forced) cooling. This indicates the capacity of the transformer to handle power at different cooling methods. The main technical specifications are as follows
| HV | 44000 Delta volts | Oil weight | 2150 kg |
| LV | 600 Y/346 Volts | Total weight | 8800 kg |
| KNAN Rating | 3000 kVA | HV | 46200V |
| KNAF | 3900 kVA | 45100V | |
| Frequency | 60Hz | 44000V | |
| HV BIL | 250 kV | 42900V | |
| LV BIL | 30 kV | 41800V |
The S-3000-3990/44-0.6 transformer feature
- Cooling Method: The transformer uses ONAN/ONAF cooling, which stands for Oil Natural Air Natural/Oil Natural Air Forced. This means that the transformer primarily relies on the natural circulation of the insulating oil for cooling, but it also has provisions for forced air cooling if necessary.
- Conductor Material: The high-voltage (HV) winding and low-voltage (LV) winding of the transformer are both made of copper (Cu) conductors.
- Insulating Oil: The transformer is filled with Type II mineral oil, which contains less than 2 parts per million (ppm) of polychlorinated biphenyls (PCBs). Type II mineral oil is commonly used as an insulating and cooling medium in transformers.
- Liquid Level and Temperature: The transformer's liquid level is maintained at 270 mm below the top of the highest manhole flange at a temperature of 25°C. The liquid level changes by 10 mm for every 10°C change in the average liquid temperature.
- Tank Design: The transformer tank is designed to withstand a complete vacuum and can also handle an internal pressure of up to 7 pounds per square inch (psi). This ensures the structural integrity and safety of the transformer during operation.
- De-Energized Tap Changers: It is important not to energize the transformer from any voltage source when the de-energized tap changers are being operated. This precaution helps prevent any potential electrical hazards during tap-changing operations.
- Pressure Limits: The transformer is designed to operate within pressure limits of 10 psi positive (above atmospheric pressure) and 8 psi negative (below atmospheric pressure). This ensures the transformer can operate safely within the specified pressure range.
- Energy Efficiency: The energy efficiency of the transformer complies with the CAN/CSA-C802.3 standard, which is based on the CSAC88 requirements. This indicates that the transformer meets the specified energy efficiency standards set for its operation.
