1. Before the installation of the open current transformer, it must be connected to the meter (or other measuring devices) for the second time to ensure that the transformer is not open for the second time; 2. Place all the open current transformers connected to the secondary line on the site and wait for installation; 3. If the on-site bus is electrical...

How a current transformer works The principle of current transformer is based on the principle of electromagnetic induction. A current transformer is composed of a closed core and windings. It has a small number of turns on the primary side winding, stringed in the line where the current needs to be measured, so it often has the full current of the line ...

1. Multi-tap current transformer. The primary winding remains unchanged, and when winding the secondary winding, several taps are added to obtain a plurality of different transformation ratios. For example, two taps are added to the secondary winding, K1 and K4 are 800/1A, K1 and K3 are 600/1A, and K1 and K2 are 400/1A, that is, the transformation ratio is 400-600-800/1A...

The excitation current is the main cause of the error of the current transformer, so reducing the excitation current can reduce the error (1) The core is made of materials with high permeability, because the magnetic properties of the core not only affect the ratio difference and angular difference, but also affect the saturation multiple. (2) Increase the cross-section of the iron core and shorten the magnetic circuit.

1) The wiring of the current transformer should comply with the principle of series connection: that is, the primary winding resistance should be connected in series with the tested circuit, while the secondary winding resistance should be connected in series with all instrument loads 2) According to the size of the measured current, select the appropriate transformation ratio, otherwise the error will increase. At the same time, one end of the secondary side must be grounded in case ...
