With the development of society and the increase of electricity demand, metering and billing technology is also constantly developing and innovating.
CT Power meter is widely used energy measurement instrument, which is generally used as a transformer meter and a large-capacity power consumption application.It has the advantages of high accuracy, good stability and easy installation, and is widely used in power systems, industrial production, commercial buildings and other fields.
CT Power meter adopt external CT(current transformer) and VT(voltage transformer) for current and voltage measurement, which reduces the connection node of the power line in the meter installation process, and can avoid the safety hazards caused by direct contact with high voltage.
in terms of current and voltage measurement, the accuracy of CT meter can reach 0.2 or even higher, which can meet various accuracy requirements of the application, also know as High Accuracy Power meter.
CT Power meter has high safety performance. Beacue isolation effect of CT(current transformer) on high voltage can effectively avoid the occurrence of electric shock accidents, and also prevent the impact of meter failure or damage on the power system.
CT electricity meter adopt separation design, CT(current transformer) and VT(voltage transformer) can be installed separately, which has the characteristics of convenient installation. In the meter installation process, CT(current transformer) and VT(voltage transformer) need to be connected to the circuit under test, and no circuit changes are required.
CT kwh meter adopts external transformer method and the measurement capacity and wide range of electric energy can be realized by replacing the current transformer and voltage transformer that meet the requirements of use.
According to the characteristics of CT kwh meter as a High Accuracy Power meter with high accuracy, large range, high safety and easy installation, it is mainly used in substations, distribution rooms and other places of energy measurement and monitoring.
In industrial production, commercial building groups are mostly used for measurement on the bus, also know as the general meter.
Monitor and control the production process to improve production efficiency and save energy.
Monitor and control the energy management of commercial buildings to achieve energy conservation and management.Because the CT energy meter can accurately measure the current, voltage and power parameters in the power system, it can monitor and control the operating status of the power system and ensure the safe operation of the power system.
