New generation distribution transformers have incorporated several advanced features and technologies to enhance efficiency, reliability, safety, and environmental sustainability. Some of these key features include:
Energy efficiency: Careful design optimization ensures very low losses during energy transfer resulting in high efficiency of over 97%.
Reliability: Stringent quality control in design, raw materials and manufacturing results in highly reliable units that provide trouble-free service for over 25 years.
Overload capability: Short-term overloading above the rated capacity is supported to account for occasional spikes in demand.
Protection features: Inbuilt devices protect the transformer from issues like overheating, voltage spikes, short circuits etc.
Minimal maintenance: Robust construction, corrosion-resistant materials, and better sealing mechanisms extend the lifespan of these transformers and reduce the need for maintenance, translating into lower lifetime costs.
Compact design: Advanced manufacturing techniques enable smaller and lighter transformers without compromising performance.
Low environmental impact: Distribution transformers utilize non-toxic, biodegradable vegetable-based oil instead of mineral oils.
These features collectively represent a significant advancement in transformer technology, aiming to meet the evolving demands of modern power distribution systems while minimizing environmental impact and operational costs.
