Japanese term (edited): �����d��

In the context you have provided, I would guess 'power surges' -
this is where higher than the rated voltage comes in over the power line, either due to lightning or a failure of voltage regulating equipment on the line.



Since the literal translation of 特高電力 is 'especially high(voltage) power', this sounds like the likely answer.


I don't have web references but as my reference I provide you my over 8 years experience as an IT administrator with experience in handling computer risk and security. Our main concerns are as you have listed here:

Theft
security breaches due to manual or automated attacks
hardware failure
power loss or power surge (We spend thousands of $$ for each of our sites to provide UPS (uninterrruptible power supply) devices and these devices also serve to regulate the incoming power if it is over spec. We see this in India all the time. Our India office has a "power cleaner" for this purpose for the entire office, not just the server room.

Please remove the word ¥"guess¥" from the first line of my answer. the sentence should read: ¥"In this context the correct term IS ¥'power surges¥'¥" I am 100% sure on this.
