  • An integrated measuring device for monitoring power which monitors, and notifies a user of, power abnormalities such as power outages, earth leakages, and surges in real time


  • Automatically record real-time abnormalities such as power outage, earth leakage, and surge
  • Leakage current and operating current can be checked in real time
  • Immediate notification through the administrator's PC or mobile phone text message when the earth leakage breaker trips
