Background
In the prior art, an electronic device generally has only a single function of temperature value overrun alarm, that is, only a temperature value is measured and then compared with a set value, for example, if the set value is 140 degrees, then an alarm is given when the set value is 140 degrees.
However, in principle, the temperature rise is closely related to the magnitude of the current. Even if a fault condition has occurred (e.g., the screws are not tightened causing the conductor contact resistance to increase), the temperature does not rise to the previously mentioned set point for the temperature alarm, such as 140 degrees above, because the current does not reach a certain level. As such, the fault cannot be identified at the first time.
