As described above, the present invention separates the load into lighting loads, computer loads, power loads, emergency power loads, air conditioning power loads, emergency loads, heat transfer loads, weak charge loads, special loads, and the like in general buildings and intelligent buildings. By installing it, the load of other systems should not be affected in case of an accident due to a specific load, and systematic maintenance is possible even after many years have passed since the construction of the building.

In case of installing lighting load alone, it prevents light flux change caused by flickering of light due to instantaneous voltage drop when starting induction motor.

When high quality and stable power is required such as computer load, it can be supplied from a separate switchgear to prevent obstacles due to noise such as flicker generated from power load.

Overheating of capacitors due to harmonic currents generated by power electronic devices embedded in uninterruptible power supplies (UPS) or converters (inverters, converters, rectifiers, etc.) for computational loads, rises in abnormal temperature of generator windings, magnetostriction of transformer cores , Overheating and burnout of power factor correction capacitor and choke coil for fluorescent lamp, overheating of cable neutral wire, increase of loss of induction motor, weakening of precision of instrument transformer, malfunction of electronic calculator and protection relay, blowdown of power fuse, etc. It is possible to establish systematic countermeasures such as the installation of harmonic prevention filters to prevent adverse effects.

In the case of power load, inverter (VVVF) is mainly used to prevent voltage fluctuations at start-up, to suppress the increase of transformer capacity, and to save energy. Therefore, it is easy to prevent the disturbance to other devices due to harmonic current generated from the inverter. Minimize the effects of excessive fault current on other devices in case of failure,

Air-conditioning power load also uses an inverter or soft starter system to operate the air-conditioning motor, so it is possible to prevent the influence on other equipment due to the generation of harmonic currents,

Emergency power load is a load operated during an emergency or power failure, and in the case of an emergency elevator, it is possible to maintain and maintain the system systematically.

In case of emergency load, by installing load required by building or fire law in case of emergency or power failure, such as emergency outlet, induction lamp, building emergency lighting, etc., the capacity of emergency generator can be reduced and maintenance efficiency can be expected.

In the case of weak loads, heat transfer loads, and special loads, it is possible to minimize the influence from harmonic currents generated by other devices or failure currents generated by motors, and the efficiency of maintenance can be expected.
