Should Dry Type Transformers Be Installed Indoors or Outdoors?
Dry type transformers are typically one of a power system’s most critical and costly components. To achieve an optimal return on your investment, it’s critical that you select a transformer with the proper voltage and rating while following the appropriate installation protocols. Choosing a location that complies with all safety codes while not interfering with […]
Read MoreInvesting in a High-Quality Transformer Design
Replacing a failed transformer comes as an unwelcome surprise with an unanticipated and unavoidable expense. Facilities managers are immediately faced with two urgent questions — “How soon can we get power back?” and “How much is this going to cost?” The answers depend on some key decisions made in replacing the transformer, but the urgency of the questions implies that […]
Read MoreDifferent Degree C-Rise Options for Dry Type Transformers
Transformers are electromagnetic devices that change the voltage levels in a circuit. Most dry type transformers contain primary and secondary windings around a magnetic steel core. Power from the incoming voltage source flows through the primary winding, while the secondary winding converts the energy and transmits it to the load. The core supports the windings […]
Read MoreWhy ELSCO Uses Class 220 Insulation in its Dry Type Transformers
ELSCO uses DuPont Nomex® Type 410 insulation exclusively in the windings of its medium-voltage dry type transformers because it provides the strongest protection against temperatureinduced failure for the longest period of time. Nomex® 410 is a NEMA/IEC Class 220 insulating material, for which the maximum allowable exposure temperature for safe use is 220°C. Insulation Has […]
Read MoreC-Rise Insulation Options for Dry Type Transformers
Because transformers convert power into higher or lower voltages, they generate heat as a byproduct. This heat causes increased temperatures in the transformer’s internal components, including the primary and secondary windings. A transformer’s temperature rise — or C-rise — is the average temperature of the windings in Celsius over the surrounding temperature when the transformer […]
Read MoreWarranties for Dry Type Transformers
Transformer manufacturers help meet the power needs of many applications for a broad industry range. Choosing a reliable manufacturer can ensure your transformers adhere to design specifications, deliver to you on time and provide long life spans. The most reputable transformer manufacturers stand above the competition by offering some of the industry’s most comprehensive product […]
Read MoreTypes of Conductors Used in Dry Type Transformers
Dry type transformers usually contain windings — or coils — that act as conductors. Transformer builds typically have primary windings and secondary windings. The primary windings create input power flow, while the secondary windings convert the power and transmit it to the load through input leads. Transformers with disc windings have conductors wound on the […]
Read MoreAverage Lead Times of Padmount Transformers in 2023
Supply chain challenges have resulted in widespread disruptions since mission-critical processes rely on delayed materials sourcing and manufacturing procedures. Padmount transformers are among these critical systems that often face long lead times for new units. When your existing system stops functioning, these lead times can set your operation back. Understanding lead times for 2023 can […]
Read MoreAverage Lead Times of Dry Type Transformers in 2023
Disruptions to the national supply chain have increased lead times across industries. For mission-critical systems, like transformers, these long lead times can cause undue downtime. It’s important to understand the expected lead times for 2023 and how you can address transformer needs despite supply chain challenges. How Long Does It Take to Get a Dry […]
Read MoreDisc Wound vs. Layer Wound Transformer
One of the most common questions when selecting a medium voltage transformer is whether to choose a disc wound or a layer wound option. Understanding the difference between layer and disc wound transformers is crucial for optimizing your medium voltage applications, as each type features unique benefits and drawbacks.
