Checklist for Helping You Select a Medium Voltage Transformer

 

Is this transformer needed for Indoor or Outdoor use?

Understanding the intended environment for the transformer is crucial for ensuring its longevity and performance. Outdoor transformers need to withstand various weather conditions, UV exposure, and potential vandalism, while indoor transformers may have different insulation requirements and space constraints.

What is the KVA rating of this transformer?

The transformer's ability to handle electrical loads is determined by its KVA rating. Accurately sizing the transformer to match the application's power consumption requires knowing the KVA rating. Oversized transformers can be expensive and inefficient, and undersized transformers run the risk of overheating and failing.

What material is used in the construction of this transformer?

The material composition, aluminum or copper, impacts the durability, efficiency, and safety of the transformer. Transformers made with high-quality, corrosion-resistant materials are better for harsh environments and offer longer service life.

How many phases does this transformer support?

Understanding the phase configuration determines compatibility with the existing electrical system. Whether single-phase or three-phase, choosing the right phase configuration leads to seamless integration and efficient power distribution.

What are the primary and secondary voltage ratings of this transformer?

Matching the primary and secondary voltage ratings to the application's voltage requirements means safe and reliable operation. Mismatched voltage ratings can lead to equipment damage, power quality issues, and safety hazards.

What is the voltage regulation capability of this transformer?

Voltage regulation is important for the transformer's ability to maintain a stable output voltage despite fluctuations in the input voltage or load conditions. Understanding the voltage regulation capability gives consistent and reliable power delivery, especially in sensitive applications.

 

Medium Voltage Transformer Types We Stock 

Medium Voltage Transformer TypeSuggested Application
Oil-Immersed TransformersSuitable for both indoor and outdoor applications in utility and industrial settings for their excellent cooling and insulation properties. The transformer gets additional protection by being submerged in insulating oil.
Dry-Type TransformersGood for indoor installations in commercial buildings, hospitals, and sensitive environments where fire safety and environmental concerns are crucial. Dry Type transformers have air or solid insulation instead of oil.
Cast Resin TransformersMade for harsh environments such as chemical plants, offshore installations, and mining operations. Cast resin transformers enjoy high resistance to moisture, chemicals, and temperature fluctuations with epoxy resin insulation.
Pad-Mounted TransformersEspecially designed for outdoor installations, Pad-mounted units have rugged enclosures mounted on concrete pads to protect against weather, vandalism, and tampering. They’re suited for residential, commercial, and industrial applications.
Unit Substation TransformersUsed in commercial and industrial facilities, data centers, and renewable energy installations. Substation transformers include switchgear and other components into a single unit for simplified installation and maintenance.
Voltage Regulating TransformersEmployed in distribution networks, industrial plants, and critical infrastructure, equipped with tap changers or control mechanisms to ensure stable voltage levels under varying load conditions, contributing to voltage stability and reliability in power systems.
AutotransformersFrequently used in grid interconnections and voltage stabilization systems where voltage conversion is required, featuring a single winding with multiple taps for efficient step-up or step-down voltage levels, offering an alternative to traditional transformers for various power applications.
