Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

Overview of Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Specifications of Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

This transformer handles single-phase power at 50Hz. It comes in two common sizes: 50kVA and 100kVA. The rated power output matches these kVA figures. The primary voltage accepts standard inputs like 11kV or 33kV. The secondary voltage provides common outputs such as 415V or 230V. Voltage taps allow adjustment, typically ±5%. This helps maintain stable output under varying input conditions.

The core uses high-grade grain-oriented silicon steel. This material minimizes energy loss. Copper or aluminum forms the windings. Copper offers better conductivity. Aluminum provides a cost-effective option. Both materials ensure efficient power transfer. The entire active assembly sits inside a robust steel tank. This tank is filled with high-quality insulating mineral oil. The oil insulates the components. It also cools the transformer effectively.

Heat builds up during operation. The oil absorbs this heat. Natural oil circulation moves the heated oil. The oil flows around the core and windings. The heat transfers to the tank walls. The surrounding air cools the tank surface. This process is called ONAN cooling. It stands for Oil Natural, Air Natural. Larger units might need radiators. Radiators increase the cooling surface area.

The transformer includes essential protection. A silica gel breather prevents moisture entry. A pressure relief device vents excess pressure quickly. An oil level gauge shows the oil volume. A drain valve allows oil sampling or removal. An earthing terminal provides a safe ground connection. These features protect the transformer. They ensure reliable, long-term operation.

Rigorous testing confirms performance. Every unit undergoes standard factory tests. These tests include resistance measurements. They check voltage ratio and polarity. They confirm no-load and load losses. Impedance voltage is also measured. Dielectric tests verify insulation strength. Additional tests like temperature rise may be performed. These tests guarantee the transformer meets specifications. The transformer complies with IEC standards. It adheres to relevant national regulations.

Applications of Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

Single phase oil filled transformers work well where three phase power isn’t needed or available. These 50Hz models use oil for cooling and insulation. The 50kVA and 100kVA sizes are common for many smaller power jobs. They are tough and reliable for everyday use.

People often need these transformers in houses or small buildings far from main power lines. They boost the voltage safely for homes. This keeps lights on and appliances running smoothly. Farms use them too. They power equipment like water pumps and small machines. The oil inside helps handle outdoor weather.

Telephone companies and internet providers use these transformers. They power remote signal boxes and cell phone towers. The oil keeps things cool even during heavy use. Small factories and workshops also rely on them. They run tools, lights, and other essential gear. The 50kVA size is good for medium loads. The 100kVA handles bigger demands.

Construction sites need portable power. These oil filled transformers are built for that. They power temporary lighting and tools. They are simple to move and set up. Solar power and wind energy projects often use them too. They connect small renewable systems safely to the local grid. The oil insulation makes them safe and long-lasting.

Shops and small businesses find them useful. They provide stable power for cash registers, computers, and lighting. The 50kVA model suits many shops well. The 100kVA supports larger stores or small manufacturing units. They are a practical choice for reliable power where high capacity isn’t necessary. Their simple design makes maintenance easier.

5 FAQs of Single Phase Oil Filled Transformer 50Hz Oil Immersed Transformer 50kVA Oil Filled Transformer 100kVA Single Phase

Here are 5 common questions about our 50Hz Single Phase Oil Filled Transformers (50kVA & 100kVA models):

What exactly is a single phase oil filled transformer?
It’s an electrical device. It changes voltage levels for single phase power systems. The core and windings sit inside a tank filled with insulating oil. This oil cools the transformer and provides electrical insulation. Our models handle 50kVA or 100kVA power at 50Hz frequency.

Why use oil inside the transformer?
The oil is crucial. It absorbs heat generated during operation. This keeps the transformer from overheating. The oil also acts as a powerful electrical insulator. It prevents short circuits inside the tank. This combination ensures stable performance and long life.

What do the 50Hz and kVA ratings mean?
50Hz is the standard electrical frequency used in many countries. The transformer is built specifically for this frequency. The kVA rating (like 50kVA or 100kVA) shows its power handling capacity. A 50kVA unit handles less power than a 100kVA unit. Choose the size matching your actual load requirements.

Where should I install this transformer?
Place it outdoors or in a well-ventilated indoor area. The oil tank needs space for heat dissipation. Ensure the location is dry and protected from direct weather exposure if possible. Good airflow around the transformer is important. Follow local electrical codes and safety regulations precisely.

Are these transformers safe?
Yes, safety is a priority. The tank is sealed to prevent oil leaks. We use high-quality mineral oil with good insulating properties. The design includes features for safe operation under normal conditions. Always operate the transformer within its rated voltage and power limits. This prevents overloads and potential hazards. Regular maintenance checks are essential for ongoing safety.
