Determining the Reliability of Protective Devices

  • Uncategorized

Circuit breakers are protective devices that need the utmost attention in order to prevent unwanted accidents from happening. Neglecting maintenance of these devices can cause electrical fires, short circuits, and overloads. A tool used in testing their effectiveness is a circuit breaker timer. It is used to measure the response time of the contacts to overloaded conditions in the power line. A power interrupter should be quick enough to be able to protect the power system.
