SPDs made for lightning surges should respond promptly to your onset on the sharply growing waveform and be capable of maintain the bottom connection through the intense overvoltage incident, then reset for their monitoring job. Most devices have two or maybe more inside factors to perform the process, and react at something all over one hundred fifty% from the standard running voltage in the system. SPD features read could be thought of as self-sacrificial and should melt away out after some time safeguarding towards a multitude of smaller surges (like normal switching surges from power transmission) or some enormous surges like immediate lightning attachments.
