In many case, the power generation capacity in electric utility is not enough to supply load consumption due to
peak load of airconditioners in summer time, heating load in winter time, over load of transmission line.
Especially, peak load problem such as certain time 13:00~15:00 or 18:00~21:00 etc. daily.
Would occur electric system crisis and make frequent power blackout due to load shedding.
In order to solve these peak load problem, electric utility shall consider a short term, mid term action and long
For short term and mid term countermeasure, Smart Automatic peak Load limit Controller is very useful and
economical device to limit peak load automatically as settable time, settable limit load.
Also, Smart PLC would be able to install for 12~35kV High Voltage Customer and low Voltage Customer with
Economical circuit breaker, or load break switch and remotely ON/OFF controllable PLC controller function by
- Remotely ON/OFF of Peak Load Controller Function by Mobile phone
- Remotely Monitoring of Peak Load Controller by Mobile phone
