Tamil Nadu Electricity Board [TNEB] — Every hour 5-10 minutes power cut

For the past 2 days there is power-cut at random every hour in nagercoil near derik junction. The power cut is at random and resumes after 5 or 10 minutes. But there is more than one such power interruption in every hour. This cause problem in work that relies on continuous power-supply for more than an hour or two. I request you to rectify the fault and give continuous power.
