The world first clamp tester which can detect DC current component in AC circuit
M-800P
FEATURES
Model 800P is the world’s first clamp meter which can detect small DC current in AC circuit in addition to general AC/DC current measurement.
By using this clamp meter, DC offset surveillance can be made easily in the actual fields like as solar inverters, etc. and it is possible to check if the DC component in AC circuit is less than 1% of the rated AC current or not, according to the regulation.
If DC component flows into transformers
In case, the bias magnetism phenomenon may happen and it may cause DC magnetic flux in the iron core. Consequently, it may possibly have bad influence on the connected apparatus by flowing larger excitation current and there would be possibility of transformer burnout due to the selective heating
