11kV Transformer Price Guide

The 11kilovolt (kV) transformer is a common power infrastructure many of us encounter daily without even realizing it. If you’ve ever driven down a rural road and noticed a square or cylindrical piece of equipment mounted on a telephone pole, that’s probably an 11kV transformer. For instance, DAELIM offers a wide option of 11kV transformer prices and types.

Installation Process of 11kV Transformers

Conduct A Standard and Specialized Transformer Tests

Performing standard and specialized tests on transformers is important to guarantee their health.
●A voltage-ratio analysis
●Single-phase and three-phase transformer polarity
●Three-phase 11kV transformer connection phases
●Temperature winding resistance calculation resistance
●Excitation current
●Transformer efficiency is affected by load loss
●Limits imposed on voltage drops under load
●Induced and applied voltages

Set Considerations and Prepare Contaminant Prevention

The transformer’s placement is of utmost importance. It shouldn’t be in the way of people or things getting where they need to go. They also must not be put in danger by passing vehicles or heavy machinery. Inspecting, assembling, and testing your transformer requires a full set of tools and components for contaminant prevention.

Maintain The Transformer Sound Level And Keep It Grounded

Remember to regulate the transformer noise, particularly when installing in quiet hallways. Because of their audible humming, transformers are most noticeable in less-populated, quieter places.

A transformer’s wiring must include grounding, which must be completed before the circuit is activated. If the windings contact the transformer core or enclosure, the static charge is dissipated, and the transformer is protected.

Additional Guidelines

Additional considerations for 11kV transformer connection and installations include:
●Establishing links that work
●Initial examination
●Injecting the energy load
●Making the right adjustments to the tap
●Final checking and testing

Standard Voltage of 11kV Transformers

High voltage is defined as greater than 1000V for alternating current and greater than 1500V for direct current by the International Electrotechnical Commission and its national counterparts. According to this criteria, an alternating current of 11kV is deemed high voltage because it is greater than 1000V. Furthermore, high-voltage transformers present an electrical arcing hazard.

Types of 11kv Transformers

11kv Single-Phase Transformers

All 11kV single-phase transformers have a single primary and secondary winding. These coils are twisted around a steel or iron core, making them exceptionally inductive. The primary winding is merged with the alternating current source, whereas the secondary winding is connected to the load. And when used as step-down transformers, single-phase models are appropriate for home use.

The primary use of 11kV single-phase transformers is in domestic and commercial settings, where the lower voltage is preferable. They are also appropriate for household and light business use because of their low price and minimal electrical input needs. Single-phase transformers have additional advantages, such as:
●Simpler construction
●Reduced manufacturing expenses
●Improved performance by producing 1000-watt AC ideal power supply

11kv Three-Phase Transformers

In contrast, the primary and secondary 11kV 3-phase transformer prices and features have thrills. There is a 120-degree gap between each pair of coils.

These transformers are housed in enclosures full of dielectric oil to control the output voltage precisely. Considering the 3-phase transformer price, they perform better when supplying electrical power in high-use settings like factories. Using 11kV three-phase transformers provides many advantages, such as:
●Reduced copper use in electrical wiring
●Low operating risk
●Increased performance of the conductor
●Work properly with long-distance electrical connections

Dry-type 11kv Transformers

Dry-type transformers can only handle up to 33kV of voltage. But most dry-type 11kV transformers rely on air to dissipate heat. The following make use of vacuum pressure impregnation to put air to work:
●Epoxy coating
●Silicone varnish
●Durable resin castings for extreme environments
In addition, dry-type transformers are preferred in interior settings like malls and hospitals since they are more environmentally safe and non-fire hazards.

Oil-Cooled 11kv Transformers

In keeping the coils at the ideal temperature for best performance, oil-cooled 11kV to 415v transformers’ prices are worth it as they submerge in mineral oil. To transformer tanks, oil is circulated through radiators.

Due to the potential for oil spillage, these transformers are better suited for outdoor installation. They’re better for the environment because they save resources and last longer without requiring extensive repairs.

Where do you use 11kv Transformers?

The voltage in homes is typically regulated using transformers 11kV to 230v. These devices transmit electricity from high-voltage transmission lines to lower-voltage local feeders. All homes in a given neighborhood receive electricity through a network of local feeders.

What is the difference between HT and LT?

High-temperature (HT) and low-temperature (LT) power supplies are common in thermal evaporation systems. HT power supply delivers high voltage for DC sputtering and cleaning of plasma growth. These generators use rectifiers to change the alternating current (AC) from the step-up transformers to the direct current (DC).

However, LT power supplies deliver a large current at a relatively low voltage. They are made up of step-down transformers that have a low primary voltage but a large secondary current.

What is an 11kV feeder?

Dry-type 11kv Transformers 2

A three-phase, three-wire, 11kilovolt (kV) distribution line is known as an “11kV feeder.” It starts at the first substation and travels through rural communities and farmlands to supply farms, homes, and small businesses. The typical length of an 11kV feeder, from one primary substation to another, is greater than 10 kilometers.

There are also cases where a feeder dies because there are no customers in the area. 11kV/433V distribution substations are located along 11kV feeders and reduce the voltage from 11kV to 400V. Agricultural water pumps and other industrial machinery require power at this voltage.
