Product information current transformer

Current transformer become the Current measurement and convert an alternating current to be measured from one phase of the electricity grid into a lower current that can be measured by measuring devices and energy meters. For example, 500 A of primary current to be measured is converted into 1 A or 5 A of secondary current which is applied to the meter. The measurement of primary current to secondary current is proportional. Furthermore, potential-free measurement is possible when using a measuring transformer. The secondary current is proportional to the primary current. This allows measuring instruments with a scaling factor to calculate and display the correct current value.
