FAQ
Can it be adapted to high-voltage three-phase three-wire circuits?
It can be connected to the high-voltage system through the matching voltage transformer and current transformer. The transformer with the corresponding strain ratio needs to be configured according to the actual voltage level.
What is the service life of the equipment?
Under normal use, the life of the core metering components can reach 10 years. It is recommended to re-check the accuracy after the life is exceeded.
Are there any special requirements for installation?
It needs to be installed vertically in a dry and vibration-free environment with an ambient temperature of -10℃~+70℃. Heat dissipation space needs to be reserved during installation.
