CT kWh meter, also known as mutual inductance energy meter, is an energy meter that measures the current of the sampling line through an external current transformer. A current transformer is a device that converts a large current into a small current proportionally, which can be used for protection, measurement, and other purposes, so the CT kWh meter can measure the load of large current. CT kWh meters are commonly used in industrial and commercial applications involving high currents because they can accurately measure large currents without overloading the measurement system, and in utility metering to measure the current flowing through power lines as well as energy consumption.

CT kWh meters use external transformers as current and voltage measurement elements, which can realize non-contact measurement, thereby improving safety and reliability.

CT kWh meter has high measurement accuracy, can make accurate measurements in a small current and voltage range, suitable for the measurement of various current and voltage levels, and the measurement accuracy class is above 0.5.

CT kWh meter has a wide measurement range, can adapt to the measurement needs of different current and voltage levels, and select a suitable current transformer according to the field load situation; For CT kWh meters that can be set to the ratio, the ratio is set to the meter according to the selected current transformer.

CT kWh meters have lower power consumption, which can save energy and reduce the cost of use.

CT kWh meters have a long service life and low maintenance costs, which can meet the needs of long-term use and high-load environments.

CT kWh meter adopts the form of external current transformer, which is easy to install; The power line of the line does not need to be directly connected to the energy meter, and the power line of the line under test passes through the current transformer and connects the signal output line on the secondary side of the current transformer to the corresponding CT kWh meter current detection interface; In addition, the power supply is connected. The current sampling and voltage sampling of the CT kWh meter are connected to the detection port of the CT kWh meter through the lead, and the installation position of the meter parent body is flexibly selected according to the on-site installation conditions.

CT kWh meter is indispensable in the field of power measurement and widely used; Professional energy meter manufacturers will have R & D and manufacturing. The following is a full-featured CT kWh meter.
