It is important that you give routine maintenance to your installation to ensure it extends its life, all electrical equipment must be checked from time to time to detect possible faults that could be avoided before becoming something more serious.
Every electrical installation can have two operating states:
i) Normal: a condition that establishes that the electrical parameters are within the permissible limits (voltage, current, frequency, impedance).
ii) Abnormal: a condition that establishes that the electrical parameters are outside the permissible limits for a given time.
When the parameters are abnormal, various faults such as overloads, short circuits, and insulation can be generated.
