In the power measurement field, the meter shunt is one of the most commonly used applications for the 250 uΩ fuse resistor. In this case, the fuse resistor is placed in the circuit so that the fuse lead of the current divider can be directly connected to the circuit, making it easy for the current divider to read the current data in the circuit. In addition, in some cases where high-precision current measurement is required, the fuse resistor can also be used to protect fragile ammeters by isolating the high-voltage part from the low-voltage part, thereby reducing the noise and interference in the circuit.

CT (Current Transformer) metering has emerged as an indispensable technology in the field of electrical power measurement and monitoring. With its ability to accurately measure current levels in high-voltage systems, CT metering plays a pivotal role in ensuring reliable and efficient energy distribution. In this article, we will delve into the technical aspects of CT metering, exploring its working principles, benefits, and the latest advancements driving its widespread adoption.

Common-mode choke: In the common filter, usually only one common-mode choke is installed, and the leakage inductance of the common mode choke is used to generate an appropriate amount of differential mode inductance,

The accuracy is unchanged for a long time, and there is no need to run the school, no installation and transportation, etc.

1) Trademark 2) The name and model of the electric energy meter (such as a single -phase fee control intelligent power meter). 3) Measurement License (CMC) Electric energy meters are used for measurement and settlement. It must have a measurement of measurement products issued by the National Technical Supervision Bureau to be legally produced.

​The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two long boxes are drawn side by side. At the same time, mark the relay word symbol "J" in or beside the long box. There are two ways to represent the contacts of relays: one is to draw them directly on one side of the long box, which is more intuitive. The other is to draw each contact into its own control circuit according to the needs of the circuit connection. Usually, the contact of the same relay and the coil side are marked with the same text symbol, and the contact group is numbered to show the difference.
