Abstract
The electric power system protection device according to the present invention includes a transformer including a primary winding and a secondary winding which are electrically isolated from each other. The primary winding is to be connected to a first electric path which is to be connected to an external power supply configured to supply AC power by use of a secondary battery, so as to receive the AC power from the external power supply. The secondary winding is to be connected to a second electric path to be connected to a power supply path from a commercial electric power system to an electric load.
