Three-phase energy meter field calibrator
and electrical instrument and the utilization rate of instrument;
3. Making the electrical instrument (rotating machine, capacitor, transformer, etc.) losses rise,
boosting the insulation aging, and thus shortening the life;
4. Enabling the relay protection, automatic instrument, computer system, and many electrical
instrument not to work properly;
5. Enabling the measuring instruments, instruments (such as: energy meter) not to indicate
or measure;
6. Interfering with communications systems, reducing the signal transmission quality, and
damaging the normal signal transmission, or even damaging the communications
instrument.
