The transformer in the community has radiation.
Radar systems, television, mobile phone and radio transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various electrical processing equipment, communication transmission stations, satellite earth communication stations, large power generation Stations, power transmission and transformation equipment, high-voltage and ultra-high-voltage transmission lines, subway trains and electric trains, and most household appliances are all sources of electromagnetic radiation.
The main impact of noise on people is within 3 meters of a transformer. According to regulations, the distance between a transformer in a residential area and a house must not be less than 3 meters, which means there is no risk of electric shock or electromagnetic radiation beyond 3 meters.

Notes on the installation and operation of the transformer:
1. In addition to the factory test by the manufacturer, the new transformer should be installed on site before it is completed and put into operation. Lifting core inspection; also after overhaul. (It does not need to be carried out when there are no bumps in short-distance transportation, but pressure resistance and other tests should be carried out).
2. When the transformer is out of service for more than half a year, the insulation resistance should be measured and the oil withstand voltage test should be done.
3. When the transformer is first put into use, it should be subjected to ≤5 full-voltage closing impact tests. After overhaul, it should be ≤3 times. At the same time, it should run without load for 24 hours without abnormality before it can be gradually put into load; and all records should be kept. . The purpose is to check whether the insulation strength of the transformer can withstand the rated voltage or operating overvoltage that occurs during operation. It is also to assess the mechanical strength of the transformer and the reliability of the relay protection action.
4. The insulation resistance of newly installed and overhauled transformers should not be lower than 70% of the manufacturer's test value at the same temperature.
5. In order to improve the utilization rate of the transformer and reduce the transformation loss, it is more reasonable when the load current of the transformer is 75 to 85% of the rated current.
