Power Transformer Power Supply Method — The 10KV high-voltage grid operates using a three-phase three-wire system with a non-grounded neutral point.
The transformer power supply in Ningbo Fenghua mainly operates in a system with a neutral point directly grounded using Yyn0 wiring method, which can provide either a three-phase four-wire or five-wire system, such as the TN-S system.
Electrical Transformer — A stationary electrical equipment used to transform alternating voltage and current for the transmission of AC power. It operates based on the principle of electromagnetic induction to transfer electrical energy.
Transformers can be categorized by their purpose into power transformers, test transformers, measuring transformers, and more. Power transformers are used for the transmission and distribution of electricity, as well as for distribution to electrical consumers. Test transformers are devices used to perform withstand (step-up) voltage tests on electrical equipment. Measuring transformers are used for electrical measurements and relay protection in distribution systems (PT, CT). A power transformer is a stationary electrical device designed to convert a certain magnitude of alternating voltage (current) into another or several different values of voltage (current) at the same frequency.
