A Complete Access To 315 kVA Transformer

315 kVA transformer is a distribution transformer. With the 315 kVA transformer, you may reduce emissions and achieve significant energy savings. They are modest, have a small loss, have low noise, and have excellent efficiency.315 kVA transformers regulate electricity by switching between large and small voltage and current-voltage sources.

They produce power, but not in the same way as generators, measured in kilowatts. You can calculate the power of transformers by k.V.A, which refers to kilovolt amperes. 

Typically, the transformer only measures the apparent power, which consists of the voltage and the current.

 

This post will teach you everything you need about the 315 kVA transformer. If you're in the market for a 315kVA transformer, use this guide to identify its features and specifications.

 

What Is A 315 kVA Transformer?

In the field of electricity, a 315 KVA transformer is an electrical device with the capacity to handle 250 kilowatts of power.

Each winding shows the number of ampere-turns required to generate one volt. Transformers with a 315 kVA rating transform the incoming electricity into the output power that can run the load.

 

The primary and secondary windings of a 315 kVA transformer usually have separate enclosures. The primary winding is the path of the input power. At the same time, the energy is subsequently transformed by the secondary winding and transmitted to the load via the input terminals.

 

In many cases, the V.A. or kVA rating of the transformer is identical to the power required by the load. For instance, a 1kVA transformer is necessary for a 1000-watt (kilowatt) load with a unity power factor. To meet modern demands, the transformer's kVA rating should be a little higher than the load's.

 

Generally, to get the most out of their transformers, businesses need to know how much power each can produce.

What Are The Types Of 315kVA Transformers?

Smaller transformers with ratings up to 315 kVA are typically single-phase, dry-type, oil-immersed transformers.

315kVA transformers are a low-cost alternative for some networks, especially those with limited populations. Here at DB Transformer, you can choose different types of  315 kVA transformers designed to meet your requirements. 

Dry Type Transformer

315 kVA dry-type transformers do not use liquid to help them disperse heat. They also do not conform to the standards for their temperature categorization. They either rely on natural airflow or a fan to keep the necessary temperatures inside these transformers.

 

Oil Type Transformer

The 315 kVA oil-type transformers are commonly applied in electricity distribution and electrical substations. They use oil as a cooling and insulating medium for their core and coils. Through circulation, oil moves through ducts within and around the coils and core assembly.

DB Transformer 315kVA oil-filled transformers include pad-mounted transformers, substation-style transformers, and oil-immersed transformers.

How Much Does A 315 kVA Transformer Weigh?

Generally, a 315 KVA transformer weight is 1660kg. There will be differences according to different transformer types, materials, efficiency values, etc.

The core consists of high-quality, cold-rolled grain-oriented (C.R.G.O.) annealed steel lamination. It has low loss and good grain characteristics. Users should insulate 315 kVA with hot oil to avoid vibration and noise and securely bolt to the frames. 

 

In most cases, insulation is necessary for all core clamping bolts. To ensure accuracy, the no-load current of a transformer with a rated voltage and frequency of 315 kVA must be less than 2% of the full-load current. The no-load current must rise by at most 5% of the full-load current for every 12% above the rated voltage.

What Is The 315kVA Transformer's Oil Capacity?

The oil capacity of a 315KVA transformer is 380 liters.

At Daelim, all transformers supplied by the company always have the required amount of oil. According to the requirements of the environment, Daelim can offer vegetable oil with UL certification.

Liters of oil advisable for 315 kVA transformer (not including oil absorbed by the core and coil assembly):

• Voltage rating of 11/0.433 kV = 500
• Voltage rating of 22/0.433 kV = 550
• Voltage rating of 33/0.433 kV =580

Keep in mind the conservator in a 315kVA transformer must be able to hold at least 10% of the oil.

For a 315kVA transformer with an oil conservator, as a rule, the conservator will hold 3% of the total oil supply. A transformer's conservator tank is the cylindrical tank atop the main tank. Once it heats, the tanks provide the oil in the transformer with breathing room.

What Are The 315 KVA Transformer Dimensions?

The 315 KVA transformer has the following dimensions: 835 mm (height), 1125 mm (width), and 1545 mm (long).

The 315 kVA tank's height should provide a minimum vertical clearance of 120 mm from the top yoke to the top cover plate. Meanwhile, manufacturers ensure that they use tie rods made of 16-millimeter-wide MS. They apply this to secure the core of a 315 kVA transformer.

 

On the other hand, the high- and low-voltage sides of 315 kVA transformers often require adequate voltage and current-rated outdoor bushings. Transformer bushings are insulating structures allowing live, current-carrying conductors to flow safely into the transformer's grounded tank.

 

Frequently, manufacturers construct these bushings in two pieces. For the outer bushing, porcelain is necessary. At the same time, the internal bushing consists of a hard insulating material like epoxy, which requires an embedded stem.

What Is The Maximum Load Of A 315kVA Transformer?

The maximum load of the 315kVA transformer shall not exceed 2% of the full load current. 

The current must be no more than double the rated value at no load. But there are always exceptions, and it usually depends on various circumstances.

 

Allowable Temperature Rise

For example, suppose the ambient temperature is below the maximum value at the rated load. In that case, a 315kVA power transformer can safely operate at a higher MVA than its rating would otherwise allow. The temperature will rise above the safe limit during the warmer months if the unit users apply it at full capacity.

 

Lower Frequency

At lower frequencies, core saturation may become noticeable. The core may still reach saturation resulting in excess primary current and some overheating despite the 17% decrease in kVA.Thus, there will be a corresponding decrease in frequency.

 

Increased in Load

If the load on the second panel of the 315 KVA transformer goes up, the current in both the secondary and primary windings goes up. As the resistance of a transformer winding is set, the secondary voltage goes down linearly. 

 

And the secondary current goes up (load increases). Also, when there is more current in the windings of a transformer, you will lose more copper, which wastes energy as heat.

Overall, overloading the transformer past its design limits could cause the temperature to rise above what is safe.

How Many Amps Can A 315 kVA Transformer Handle?

A 315 kVA transformer can handle 120 volts at 1515.4446 amps.

In order to calculate kVA, you need to know at least two things:

1. to what extent the load's line voltage is higher than (V)
2. a phase current at full load that (I)
3. In the case of three-phase transformers, kVA = (V * I * 1.732) / 1000

 

315 (kVA) to amp-hours (A/H) conversion. Multiply 315 kVa by 1000, then divide the result by the voltage to get the current in amps.

 

Therefore,  315kVA equals 1515.54446 A amps at 120 volts, three-phase.

 

Generally, you can calculate the kVA rating by multiplying the winding voltage by the current through the winding at full power.The number of turns in a winding determines its maximum allowable voltage. If there is a voltage drop, the kVA rating will decrease accordingly.

 

What Are The 800 kVA Transformer Dimensions?

The 800 kVA transformer has the following dimensions: 1780 mm (height), 2160 mm (width), and 2513 mm (long).

Other specification includes the following:

• Input: 22,000/4,000 Volts
• Phasing: 3 Phase
• Roughly 5% Impedance
• Weighing in at 2650kg
• The oil capacity of 645L

An 800 kVA transformer's winding material provides adequate permeability, and no bubbles form. You can also ensure that manufacturers keep it at a minimum partial discharge. In addition, the precise mating of the HV and LV windings guarantees solid structural integrity. It also offers resistance to short circuits and vibration.
