FAQ


What is a dry type transformer?

As safety and eco-awareness take center stage in modern businesses, the popularity of Dry Type Transformers is growing. Unlike traditional transformers, these don't use oil, opting for special fire-resistant insulation that significantly lowers the risk of fires.


Can these transformers be used outdoors?

Yes, our Dry Type Transformers offer flexibility in deployment as they are made for both outdoor (IP 45) and indoor (IP 21–23) installations.


Can Makpower's transformers withstand short circuits?

Yes, our Dry Type Transformers are engineered with excellent short-circuit strength. It ensures reliable and durable performance


What is the tap changing mechanism and how is it operated?

Tap changing is conveniently managed through links or an off-circuit switch with a handle on the enclosure.


Are these transformers compliant with the international standards?

The Dry Type transformers are per IS 11171/SAN 180 and IEC 60076-20 standards ensuring the transformer meets international standards for quality of design, manufacturing, and performance.


What is the difference between a Dry Type Transformer and an Oil Type Transformer?

Dry-type transformers use solid conductor insulation materials like Nomex which helps in eliminating the need for liquid cooling. In contrast, oil-type transformers depend on oil for insulation and cooling. The choice depends on factors like safety, maintenance, and environmental considerations.


How should maintenance of a Dry Type Transformer be carried out?

Routine maintenance of dry-type transformers includes cleaning, inspection of insulation, and verifying the condition of components. Additionally, attention to cooling systems, like fans and vents, is crucial for long-term reliability.


What is breakdown maintenance for a Dry Type Transformer?

Breakdown maintenance of dry-type transformers involves mitigating the issues after a breakdown occurs. Prompt identification and repair of faults are crucial to minimize downtime and prevent further damage.


What cooling method is employed in Dry Type Transformers?

The cooling method of Dry type transformers includes natural air circulation or forced air methods. Ventilation through cooling fans or vents ensures efficient heat dissipation without the use of liquid coolants.


What should be included in a Dry Type Transformer maintenance checklist?

A dry-type transformer maintenance checklist should include items like checking for dust, inspecting insulation, monitoring temperature, verifying connections, and ensuring proper functioning of cooling systems. Regular adherence to this checklist enhances the transformer's lifespan and reliability.
