DIFFERENCE BETWEEN POWER TRANSFORMER AND DISTRIBUTION TRANSFORMER

In the previous article, we have discussed the total losses occurred in the transformer. For good experience, read this article in DESKTOP MODE in any browser.

Total losses in transformer 

In this blog, we will discuss the difference between the power transformer and distribution transformer with design and operational perspective. 

	Power Transformer		Distribution transformer
1	The power transformer is used in the transmission network	1	The distribution transformer is used in the distribution network
2	Voltage level > 33 kV	2	Voltage level < 33kV
3	Fewer Load fluctuations	3	More Load fluctuations
4	The consumer is not directly connected	4	Consumers are directly connected
5	While designing copper losses are kept the minimum.	5	While designing iron losses are kept the minimum.
6	CRGO steel is used in the core of this transformer.	6	Amorphous steel is used in the core of this transformer.
7	Copper losses and iron losses take place steadily throughout 24 hours.	7	The copper loss takes place based on the load cycle of the consumer and iron loss take place steadily throughout 24 hours.
8	Full load copper loss is almost the same as an iron loss.	8	Full load copper loss is twice of the iron loss
9	Efficiency maximum occurs at nearer to the full load	9	Maximum efficiency occurs at 70-75% of full load.
10	Specific weight is less	10	Specific weight is more
11	Average load on the power transformer is almost nearer to the full load.	11	Average load on the distribution transformer is 70-75% of the full load.
