Distribution transformer, referred to as "distribution variable", refers to the power distribution system according to the law of electromagnetic induction to transform the AC voltage and current and the transmission of AC energy of a static appliance. Some regions will be below 35 kV (mostly 10KV and below) voltage level of power transformers, called "distribution transformer", referred to as "distribution variable". Installation of "distribution transformer" sites and places, both substations. Distribution transformers should be installed on the column or open-air floor mounted. Details of its installation, installation precautions, supply and distribution methods, capacity selection, operation and maintenance.
Salient Features of Distribution Transformer
Modern distribution transformers incorporate some salient features that make them suitable for the demanding requirements of power distribution:
1. High efficiency: Careful design optimization ensures very low losses during energy transfer resulting in high efficiency of over 97%. This keeps electricity costs low by reducing wastage.
2. Reliability: Stringent quality control in design, raw materials and manufacturing results in highly reliable units that provide trouble-free service for over 25 years.
3. Overload capability: Short-term overloading above the rated capacity is supported to account for occasional spikes in demand.
4. Protection features: Inbuilt devices protect the transformer from issues like overheating, voltage spikes, short circuits etc.
5. Minimal maintenance: Robust sealed tanks with long-life insulating oil minimize maintenance requirements.
6. Compact footprint: Pole-mounted transformers utilize minimal ground space.
7. Low environmental impact: Distribution transformers utilize non-toxic, biodegradable vegetable-based oil instead of mineral oils.
