harmonics detector SHD-V6

Semiconductor-applied equipment to control power by thyristor, etc. is getting popularity from small-capacity home electronics to large industrial equipment along with the recent development of power electronics technology. Along with this trend, distrotion of system voltage caused by harmonics current is increased and harmonics disturbance such as heat disturbance of phase advancing condenser is occuring.This product constantly monitors voltage of power distribution system and outputs when alarm setting is exceeded in order to prevent equipment disturbance caused by these harmonics. Phase advancing condenser is separated by using this output and some measure to prevent heating/damage of equipment can be taken.Connect timer, etc. to the back of this product to secure detection period in line with purpose.
