Product Information

A malfunctioning or broken-down transformer can lead to costly delays and make your business less profitable. Keep your operations running efficiently by staying on top of transformer repairs or getting a custom new system from ELSCO Transformers. Our essential staff members have over two decades of experience in the industry, and we parlay that extensive experience, knowledge and expertise into giving you reliable units that will run dependably and perform well for years. In many industries, including health care, manufacturing, electrical contracting, higher education and corrections, reliable, high-quality transformers are essential for keeping operations running efficiently. Large facilities and industrial processes require substantial amounts of power, and they need dependable transformers to convert the energy coming from the power plant into a form they can use for their equipment and building utilities. If the idea of performing calculations when you need to figure out kVA seems daunting or unappealing, you can always turn to charts. Many manufacturers supply charts to make determining the correct kVA easier. If you use a chart, you’ll locate your system’s voltage and amperage in the rows and columns and then find the kVA listed where your chosen row and column intersect.

A three-phase transformer can take one of a few different forms. It typically has three lines of power, where each line is out of phase with the other two by 120 degrees. The kVA unit represents kilovolt-amperes, or 1,000 volt-amperes. A transformer with a 1.0 kVA rating is the same as a transformer with a 1,000 VA rating and can handle 100 volts at 10 amps of current. So you’ll multiply your kVA rating by 1,000 and then divide by the amperage. If your transformer has a kVA rating of 75 and your amperage is 312.5, you’ll plug those numbers into the equation — 75 * 1,000 / 312.5 = 240 volts. How to Determine Secondary Voltage We also offer a few different types of brand-newmedium voltage transformers, including dry-type, pad-mount,unit substationandstation-type transformers. We’re also happy to develop custom-built transformersto meet your facility’s unique needs and specifications. We have years of experience supplying transformers for various industries, includingelectrical contractors,electrical supply houses, hospitals and medical clinicsandmanufacturing facilities, among many others.

You can calculate the voltageof the secondary circuit by using a ratio of the voltage drops through the primary and secondary circuits, along with the number of circuit coils around the magnetic part of the transformer. We’ll use the equation t 1/t 2= V 1/V 2, where t 1is the number of turns in the primary circuit’s coil, t 2is the number of turns in the secondary circuit’s coil, V 1is the voltage drop in the primary circuit’s coil and V 2is the voltage drop in the secondary circuit’s coil. Let’s say you have a transformer with 300 turns in its primary coil and 150 turns in its secondary coil. You also know that the voltage drop through the first coil is 10 volts. Plugging these numbers into the equation given above yields 300/150 = 10/t 2, so you know t 2, the voltage drop through the secondary coil, is 5 volts. How to Determine Primary Voltage Used to distinguish individual users by means of designation of a randomly generated number as client identifier, which allows calculation of visits and sessions. Thanks you for choosing our product(s). We offer a 12 month warranty for parts and labour against any defects in components or faulty workmanship in manufacturing. You can determine that primary voltageby using the ratios of current and voltage from the transformer’s primary and secondary coils. Maybe you know your transformer has a current of 4 amps and a voltage drop of 10 volts through its secondary coil. You also know your transformer has a current of 6 amps through the primary coil. What should the voltage drop through the primary coil be?

Very easy company to deal with, efficient and attentive. Deliver on the date we request. Competitive prices. Great company. Alternatively, you may have the kVA of your transformer and want to calculate the necessary voltage. In that case, you can adjust the equation we used above. Since you know kVA = V * l / 1,000, we can solve for V to get V = kVA * 1,000 / l. Constant pressing of the override button on this transformer is not advised as it may lead to default of product not covered under warrantyIn the example above, you would multiply 150 by 50 to get 7,500 and then divide that number by 1,000 to get 7.5 kilowatts. A single-phase transformer uses a single-phase alternating current. It has two lines of alternating current (AC) power.Below are a few common types: All information obtained while using this calculator should be confirmed by a qualified electrical contractor or engineer. The transformer typically consists of two windings, a primary and secondary winding. Input power flows through the primary winding. The secondary winding then converts the power and sends it to the load through its input leads. A transformer’s rating, or size, is its power level in kilovolt-amperes. Our transformers are generally double wound, enclosed in a steel or insulated enclosure, usually offering high levels of ingress protection.

When you’re figuring out kVA size, it’s helpful to have the terminology and abbreviations straight before you begin. You’ll sometimes see transformers, especially smaller ones, sized in units of VA. VA stands for volt-amperes. A transformer with a 100 VA rating, for instance, can handle 100 volts at one ampere(amp) of current.

The calculation for a three-phase transformer kVA is a little different from the calculation for a single-phase kVA. Once you’ve multiplied your voltage and amperage, you’ll also need to multiply by a constant — 1.732, which is the square root of 3 truncated to three decimal places: To determine your kVA size, you’ll need to make a series of calculations based on your electrical schematics.
