Why Should we Use a Fault Indicator?

---- Rapidly indicate the fault circuit and fault point, lessen the blackout area.

---- Shorten the time of troubleshooting, improving the reliability of power supply.

---- Accurately indicate the instant fault, which is conducive to rule out the power supply problems.
