Intelligent transformer

Product Overview

Based on the first and second fusion design of the intelligent transformer will be metering, measurement, protection sensors and the corresponding power measurement unit, protection and control unit, GPRS or other ways of transmission unit, performance analysis unit and transformer for integrated design, data localization processing or open inviting, realize intelligent monitoring, energy saving and reduction of energy consumption, improve the safe operation factor of the equipment, to avoid the uploading of large data, with excellent electrical performance and significant economic benefits.

Intellectual Property Rights

"ZL200510048228.9 A high-voltage signal sampling method that can be adapted to the needs of metering, measurement or protection", "ZL200820187754.2 Combined Sensor" and other 9 other ancillary patented technologies.

Product features

1. Localized data processing reduces the transmission of a large amount of information.

2、No external connection lines, effectively preventing the occurrence of power theft, without the need to add another anti-power theft device.

3、High-voltage side eliminates the need for multiple TVs, avoiding the occurrence of faults due to resonance, odd harmonics, operational overvoltage, system overvoltage or lightning impact.

4、The sensor is installed near the neutral point, but the insulation is designed according to the rated voltage, which improves the safety performance.
