Name: Power Distribution Monitoring System
The Power Distribution Monitoring System is not only a smart power meter for measuring the power distributor voltage, current, factor, watts, frequency, active power, reactive power, when over current or exceed the pre-set value, will alarm immediately.
can be used for monitoring the oil temperature, oil level of the transformers. GSM 3G Wireless Power Line monitoring.
also can be used as a wireless security alarm system for the transformers, e.g.: theft-proof, fall down, and so on.
