Power Meter and Power Transformer Monitoring System

The GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller was designed as a smart GSM/SMS/GPRS/3G  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 and send SMS to users immediately.

The GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller also can be used for monitoring the oil temperature, oil level of the transformers. when the oil temperature or level exceed preset value, will alarm and send SMS to users immediately.

Moreover, it can be used as a wireless transformer monitoring system for the transformers, e.g.: theft-proof, fall down, and so on.
