Voltage Spike
A voltage spike is a sudden increase in electrical power that can damage equipment and appliances. Think of it like a surge of water pressure in a pipe, but with electricity. Electrical repair professionals often deal with preventing and fixing damage caused by these spikes. They might appear in job descriptions when companies need someone to install protective devices, repair damaged equipment, or maintain electrical systems. Other common terms for this are 'power surge' or 'voltage surge.' Understanding voltage spikes is crucial for roles involving electrical maintenance, repair work, or system protection.
