Load monitoring is the technique of tracking the various types of electrical loads coming on to the power system during a given period of time. Non-intrusive monitoring2 is the monitoring of any system or a parameter of the system without actually entering the system i.e., without the system feeling the presence of the monitoring system.
Hence, non-intrusive load monitoring is the monitoring of the electrical load coming onto the system without actually entering the premises.
The interest among the research community to obtain individual load information such as the nature of the load, its energy consumption, the duration for which it comes on to the system and the time of the day when it was on and off etc. in a network has given rise to many methods of doing so.
However, majority of these methods are intrusive3 in nature since they require the installation of sensors and other data acquisition hardware4 to each device in the circuit. This not only makes the system intrude into consumer?s property but also makes it very expensive.
Load monitoring is the technique of tracking the various types of electrical loads coming onto the power system during a period of time. NALM is the monitoring of any system or a parameter of a system without actually entering the system. NALM has wide range of applications such as power monitoring of devices, monitoring of remote loads & monitoring of individual loads.
Also CIMS (centre for intelligent Monitoring system) is used to monitor wide range of parameters such as temperature, Light pressure, colour, sound radio freq, electrical current and voltage etc.
To conclude that, non intrusive load monitoring is a very cost effective monitoring system in many applications. This can also provide a very convenient and effective method of gathering load data compared to traditional means of placing sensors on each of the individual components of the load...
