I rented a house and bought my own appliances. The voltage in the residential area is too high and the electrical appliances are burnt out. Who should I ask for compensation? Landlord? Or real estate?

First, you have to solve the problem of proof. First, how many households have this happened? This kind of thing must be done together to be effective. If this happens to one or two households, it's hard to say who is responsible. Second, did the power bureau repair the line on the day of the incident? Has the power bureau informed your property? Does the property have a notice of community announcement? Because electricity is issued by the electric power bureau in charge of the ground power grid, and then to the special distribution room in the property community, and then to the residents' homes, which link has gone wrong?

Different departments are responsible for different links.

But since you are a tenant, you should communicate with the owner and summarize the damage of your electrical appliances. It is best to photograph the damaged electrical appliances and hand them over to the owners and other tenants to complain about the property and ask them to reply within a time limit. The cause of the matter, and then talk about compensation for losses.
