Substations are part of the electrical generation, transmission and distribution system. Transformers are contained inside many of them, and their job is to transform voltage from high to low or vice versa, depending on their location within the distribution path.
    Besides transformers, substations usually house switches, protective devices and control equipment. In large substations, circuit breakers are used to interrupt any short circuits or overloads that may occur.
    No one should approach a substation, touch the fence or enter the gate unless they are authorized to do so.
    Paying attention to individuals and activity around substations and other utility equipment helps keep everyone safe. Here are some things to look for:
•    Take notice of individuals in street clothes working near or on utility equipment; if you see this, please report it immediately.
•    Notice whether individuals are dressed in proper personal protective gear or have utility identification badges.
•    Check vehicles or work trucks in the area for utility branded logos or information.
•    Report any suspicious behavior you see, including non-utility employees tampering with utility poles, meters, padmount transformers or other equipment.
    If you notice anything unusual at a substation, please report it to the utility. Examples include the following:
•    An open or unlocked gate.
•    A damaged fence.
•    Obvious damage to equipment inside the fence.
    Call 911 and then the electric utility if you see smoke or fire inside a substation. Same for non-utility workers inside the substation fence.
    Never try to address an issue yourself. Please report any suspicious activity or damage to the police or the utility.
