The Ultimate FAQ Guide To 167 kVA Transformers

What Is A 167 kVA Transformer?

A 167 kVA transformer is a type of industrial transformer that reduces high-voltage, three-phase energy from the grid to safer, single-phase power.

This unit's low-temperature rise and high efficiency make it well-suited for use in several indoor and outdoor locations.

Such locations are electrical rooms, air-conditioned building spaces, underground vaults, and similar places.

Power Rating

The transformer has a 167 kVA rating, meaning it can handle 167,000 V at 1,000 A.

Features and Specifications

There are three porcelain bushings on the secondary side of the 167 kVA transformer, and two on the main side to handle the high voltage.

The grain-oriented steel core of an overhead distribution transformer is generally enclosed with a single coil and split into two core loops. 

Tin-plated terminals with either copper or aluminum are usually located on both the primary and secondary sides.

The 167 kVA transformer requires no additional fans or mounting brackets; Thus, it is usually cooled only by air. 

The 65-degree Celsius temperature increase helps reduce heat loss, improve reliability, and extend the lifespan of this device.

Insulation Fluid

The use of insulating fluid in a 167 kVA transformer can vary depending on the specific design and requirements. Commonly, mineral oil is used as the insulating fluid due to its excellent electrical insulation properties and cost-effectiveness. However, there are alternative options available such as vegetable-based oils or synthetic oils, which may offer advantages such as improved environmental friendliness or enhanced fire safety.

As for Daelim Transformer they offer a selection of transformers, including single-phase pole-mounted and pad-mounted transformers. Single-phase pole-mounted transformers are typically used for residential applications where power is distributed through overhead lines. On the other hand, pad-mounted transformers are commonly used for commercial or industrial applications and are installed in ground-level enclosures for ease of access and maintenance.

Mount

The 167 kVA transformer often features a durable casing, which makes it suitable for use in challenging conditions. This robust casing helps protect the internal components of the transformer from external factors such as weather, dust, and other potential hazards, ensuring its reliable operation over an extended period.

To facilitate installation, the transformer is typically equipped with lifting lugs and hanging brackets. These features allow for easy and secure mounting on poles, simplifying the installation process. The lifting lugs provide attachment points for lifting equipment, making it convenient to transport and position the transformer during installation. The hanging brackets, on the other hand, aid in securely suspending the transformer on the pole, ensuring stability and proper alignment.

By incorporating lifting lugs and hanging brackets, the 167 kVA transformer enables efficient and hassle-free installation on poles, reducing the time and effort required for deployment.

Dimensions

The 167kVA transformer dimension is not large, because the capacity is not big. For the precise dimensions of the 167kVA transformer, you need to confirm with the supplier. The total mass of the 167 kVA transformer is about 1000 kg.

What are the different types of 167 kVA transformers?

167 kVA Single Phase Pad-Mounted Transformers

Pad-mount, also known as the pad-mounted transformer is an electric ground-mounted energy distribution transformer within a locked steel cabinet, which is positioned on the concrete pad. Because all energized connections are safely enclosed within an enclosed metal structure that is grounded and a pad-mount transformer is able to be placed in areas that do not allow for a fence. Pad-mount transformers can be used conjunction in conjunction with underground electric power distribution lines that are located at service drops to lower the initial voltage of lines to lower voltages that are supplied to customers of the utility. A single transformer could be connected to one building or many houses. Single-phase pad-mounted transformers are available with power ratings ranging from 25 to about 250 kVA and typically include switches and fuses. The primary power cables are connected via elbow connectors that can be controlled by a Hot stick and allow for flexible repair and maintenance.

What is the purpose of 167 kVA Pad-Mounted Transformers?

167kVA pad-mounted transformers, which are the large green utility boxes you see in the city are used for lower high voltage to the normal household voltage to power appliances, electronics as well as lighting. They aren't protected as overhead lines or substations are. While they might appear suitable for use as workbenches and climbing hurdles but electrical equipment could be a danger to those who come near it. Users should be aware and remain at an appropriate distance. United Power crews also need access to a safe area for repairs and maintenance. Obstacles, like fencing and landscaping, should be kept free from electrical devices. Although it is appealing to "camouflage" transformers by planting a garden remember that cooperative teams require a minimum of 10 feet of space at the front of a transformer mounted on a pad and four feet to the sides and rear that surround the house. This allows workers to work safely with the tools needed to work with equipment that is energized. This also gives crews the ability to maneuver without risk should any problems arise. In many of the newer residential developments and subdivisions pad-mounted transformers are increasingly common and, in many instances, are situated on property owned by the consumer. They are linked to primary high-voltage lines and secondary lines may extend from the transformer into various directions beneath the ground. Be aware of this when planting trees or trees, erecting fence posts or installing sprinkler systems, or digging in the vicinity of an electric transformer. It is recommended to call 811 prior to digging in order to make sure lines are in the right place to ensure your project does not interrupt utility service, and cause injury to a person or cause more harm.

167 kVA Pole-mounted Transformers

167 kVA Pole-mounted transformers are distribution transformers for electric utilities that are affixed to an electrical pole of service (wood or cement) and usually are placed at the same level as the overhead cables. Pole-mounted transformers are commonly used breadbox transformers utilized to convert distribution voltage to 120/240-volt power that is used in commercial and residential installations with low volumes. Pole-mounted electrical transformers can be found in large rural regions. They range between 16 kVA and 100kVA and convert 11,000-33,000 volts to a lower voltage of 400 volts. Pole-mounted transformers are relatively tiny in both size and mass making it easy to mount them on single-pole structures. They can also be installed on larger units and can be placed on two-pole structures which are approximately 5 meters high above the ground. The transformers are therefore not accessible which reduces the chance of injury to animals as well as individuals, as well as reducing the risk of vandalism. In extreme climate conditions and located in remote locations, reliability is built into the specifications of these electrical transformers. Tanks are designed to limit the accumulation of water as well as substances that cause corrosion. Protective coatings are put on tanks to stop corrosion. In the coastal regions, tanks are zinc-sprayed. In areas with high corrosive conditions, tanks are constructed from Stainless as well as 3CR12.

167 kVA single-phase Transformer

A 167 kVA single-phase transformer works on single-phase power. It has two parts, magnetic and electric. The magnetic part of the transformer is made up of a magnetic iron core and the electric part is made up of a copper transformer. For more information about how a transformer is constructed, please read our article electric transformers.
Because direct current doesn't create an electromagnetic field, only alternating current can operate the transformer. The single-phase transformer does not have moving parts, so there is no mechanical friction. A single-phase transformer is highly efficient because there are very few energy losses.

An alternating current is a condition in which a transformer's primary wounding comes into contact with an electromagnetic field. This creates an alternating magnetic field. Through mutual induction, a part of the generated magnetic fields links with the secondary winding and produced a current. The secondary windings are inducible with the same frequency and voltage as the primary windings. Faraday's Law is able to determine the value for the induced voltage.
