a step-up substation
Product Introduction
Step up substation is a key hub facility in the power system, whose core function is to raise the low voltage electrical energy output by the generator to high voltage or ultra-high voltage through transformers to meet the demand for long-distance transmission.
This type of substation is usually installed inside or around power plants, consisting of transformers, high and low voltage distribution equipment, and related buildings, with comprehensive functions such as energy collection, distribution, voltage conversion, and operation control.

FAQ
1.What is the difference between a step-up and a step down substation?
If you need to increase the voltage, you'll want a step-up transformer. If you need to decrease the voltage, choose a step-down transformer.
2.What is step voltage in substation?
The difference in surface potential that could be experienced by a person bridging a distance of 1 m (3') with the feet without contacting any grounded object. Step example: A person is walking with one foot at 900 V and the other at 800 V, resulting in 100 V step voltage.
