How to look at the current in dry-type transformers

May 09, 2023

Dry-type transformer is an important power equipment, but also an important electrical appliance, dry-type transformer has a certain voltage and current, for the dry-type transformer current can be calculated. There are many main methods for calculating the current of common dry-type transformers, so how to calculate the current of dry-type transformers? Let's go to know in detail with the editor of the dry-type transformer factory:
Dry-type transformer calculation current formula:
According to the calculation formula, the rated current of dry-type transformer: I=S/(root number 3*U) 0/0.4KV The rated current of dry-type transformer is calculated on the primary side is similar to 0.058*KVA (dry-type transformer volume, specification model 10kV/0.4kV) and the secondary side is similar to 1.44*KVA (dry-type transformer volume, specification model 10kV/0.4kV) The subtitle responds to the following calculation of the low-voltage side rated current of 50KVA dry-type transformer: 50*1.44=72A calculate 80KVA dry-type transformer low-voltage side rated current: 80*1.44=115.2A calculate 100KVA dry-type transformer low-voltage side rated current: 100*1.44=144A or so is people to everyone to introduce the dry-type transformer current calculation and current requirements, for everyone to carry out reference, in fact, the use of dry-type transformers is more critical, should show the advantages of dry-type transformers, promote the safe and stable operation of dry-type transformers.
