What is a Mini Substation Transformer?
The place where the voltage is changed is a power facility in the power system that transforms the voltage, receives and distributes electrical energy, controls the flow of power and adjusts the voltage. It connects the power grids at all levels of voltage through its transformers.
Substation is the assembly of some equipment to cut or connect, change or adjust voltage. In the power system, the substation is the gathering point of power transmission and distribution.
What are the ratings tech data of a substation transformer?
The typical rating tech data: Primary voltage: 30kv to 220kV
Secondary voltage: 6kv to 69 kV
Capacity: 1000kva to 180mva
Which transformer is used in substation?
Primary voltages of a substation transformer usually ranges from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes, but 600 volt through 35 kV secondary voltage ratings are also available.
What is the difference between a substation and a mini substation?
In fact, small substations are like normal substations, except that the transformers are usually smaller (lower kVA rated), there are fewer means of secondary distribution equipment (circuit breakers, switchgear, etc.), and the complexity of protecting transformers and feeders may also be Lower and metering control systems. Small submarines usually only include a power transformer, a set of primary fuses and some kind of overcurrent protection on the transformer secondary (breaker or fuse), possibly a load tap changer, and some fairly basic secondary metering , depending on which load service is required.
