The 500 Kva pad mounted transformer aim to reduce high voltage to the usual household voltage needed to power gadgets, appliances, and lighting. These transformers are not insulated, in contrast to substations and overhead lines.
Transformers are crucial for supplying buildings with electricity. Additionally, they ensure that your appliances operate safely to lower the chance of shocks and other catastrophes.
The leading manufacturer of electrical equipment and transformers around the globe is DAELIM, which has had a reputation for dependability and trustworthiness for more than 15 years. Consumer problems are swiftly answered by experts and professional staff of DAELIM.
Unlike substations and overhead lines, these transformers are not shielded. Electrical equipment can nevertheless be dangerous to anyone who comes into contact with them, even though it may seem safe to use as workbenches and climbing barriers.
While providing the safe voltage levels required in residential areas, 500 kVa pad mounted transformers can transform high electrical power up to 500 kV.
This industrial transformer has a rating of 500 KVA (0.5 MVA). Its main voltage is three-phase 12470Y/7200 grounded Wye, while its secondary voltage is three-phase 480Y/277 Wye. The device has dead-front primary connectors and a primary radial feed for single installs.
Aluminum is a lightweight, cost-effective, and performance-improving material for transformer windings. Due to their higher resistivity than copper, aluminum windings have fewer eddy losses. This transformer has a five-legged core design with a rectangular coil, three coils, and four core loops.
This appliance has a 65°C temperature rise for less heat loss, greater dependability, and a longer lifespan. The transformer offers 500 KVA at a temperature rise of 65°C (0.5 MVA). Generally, the transformer satisfies minimal efficiency norms (does not meet DOE 2016 efficiency standards).
This unit can be used in outdoor regions, electrical rooms, air-conditioned spaces in buildings, underground vaults, and similar sites because of its minimal temperature rise and great efficiency.
This transformer promotes the environment while delivering owners significant energy savings. Higher efficiency increases the transformer’s lifespan while also saving owners money through lower energy costs and a lower total cost of ownership.
General uses, industrial locations, electrical rooms, underground vaults, production facilities, steel plants, offshore, commercial, military, processing plants, electric power distribution, utilities, public places, and more.
Prices vary according to the brand, design, and ancillary features that set a particular transformer apart from its rivals.
Here are some tips to consider for safe usage of pad-mounted transformers:
Routine Examination – The outside of the equipment should undergo routine inspections regularly. Also, check if each instrument is functioning properly regularly.
Samples of Dielectric Fluid:
1. At least once per year, samples of the media fluid should be taken. DGA must examine the samples that were gathered (Dissolved Gas Analysis.)
2. The most crucial approach to assess the pad mount transformer’s condition during DGA testing.
3. Traditional oil testing can detect a dangerous internal issue before it harms the equipment.
Pad-mounted transformers’ shapes and sizes depending on the manufacturer’s preferences.
The single-phase transformers with pads with loop protection are intended to enable adequate coordination with upstream and downstream protective devices while protecting the loop or downstream section of a feeder. When a fault develops downstream in this design, the VFI trips and isolates the fault, keeping the transformer load operational.
Usually employed to power residential regions and modest industrial locations, these pad-mounted transformers. As a result, pad-mounted, single-phase 500 kVA transformers may weigh up to 4000 lbs.
The windings, iron cores, fuses, and high-voltage load switches are housed in the oil tank beside the three-phase pad-mounted transformer. Additionally, the oil tank holds a substantial volume of transformer oil.
The typical proportions of a three-phase 500 kVA pad mounted transformer are 68″ by 62″ by 70″, weighing about 5000 lbs, including 200-gallon mineral oil.
Transformers mounted on pads come in two designs: loop feed and radial feed.
These three-phase transformers with pads can reduce voltage levels and carry out operations similar to standard transformers because they comply with the same standards. The sizes of 3-phase pad-mounted transformers are similar to those of other transformers.
The market offers a range of sizes. You can expect something with substantially smaller dimensions than the massive transformers. Due to its similar size to a standard kitchen cabinet, installation is straightforward.
The primary voltage enters a cable that can sustain 14,400 Volts for it to function. Generally, the wire enters an H1-A bushing before passing through the transformer and windings. After that, it passes through the Z bars’ side. It leaves the cable at the connection points and travels from the Z bars to the predetermined location or through the meter.
Generally, it provides between 220 and 240 volts for homes. When transferring alternating current power between primary and secondary circuits, transformers are frequently used to change the electrical energy from one value to another. Often without compromising the consistency.
The 500kVA transformer is typically in the end-use area for household lighting, industrial production, etc. Generally, the transformer converts electrical energy into the power distribution system.
In a Bitcoin mining power system, power transformer configuration is mostly determined by MW: So, 4 sets of 2500kva step-down transformers are needed for 10 MW.
Pad-mounted and small substation transformers are the two primary types of step-up transformers appropriate for crypto farms. Large crypto farms typically prefer pad-mounted transformers. Mini substation transformers are typically purchased by small and medium encryption farms.
1. Output power: The secondary winding must be able to deliver the rated power to the load for the designed transformer to function as intended.
2. Operational efficiency: This factor establishes the maximum power loss the transformation will tolerate.
3. Maximum temperature rise: The ambient temperature, heat dissipation capability, altitude, and other elements must be considered when the transformer operates under specific conditions.
Transformers on residential pads are projected to last more than 30 years. Even residential pad-mounted transformers have been in use for more than 50 years. It indicates that you won’t need to be concerned about them wearing out quickly in terms of longevity.
Pole-mounted transformers are mounted atop electric poles. These are widely used in areas with low-power industrial lighting in commercial and residential buildings.
Meanwhile, utility power transformers are known as pad-mounted transformers because they are contained in closed steel or metal cabinets that rest on tiny concrete pads. They usually reside in places where there is little space for enclosed enclosures.
With overhead electrical lines, pad-mounted transformers are also widely used. They focus on bringing the primary voltage down to a secure level for consumer use.
Utility distribution transformers with 500 Kva pad mounted transformer is frequently utilized in industrial environments. The greatest transformer for supplying electricity to residential areas is this one as well.
Nevertheless, following the right installation procedures is crucial to guarantee that your transformers will operate at their peak efficiency despite its benefits. Additionally, care should be used when handling and approaching large power loads.
DAELIM is a prominent producer in the electrical sector. As a result, your transformer will be held to the highest standards following the company’s business values, ensuring that you get a reasonably priced, high-quality transformer worth your money.
