To insure the system class, it is recommended to use type TCH high precision

transformers. See the M7 family of current transformers.

CVMk2 has no battery. When supply falls down the analyzer do not store electrical

parmeters and no quality events. Is very important to guarantee the supply of the

device from an interrupted source (Batery, SAI, ...)
