MR series current transformer is a fully enclosed indoor product with plastic shell. It is applicable to power metering, current measurement and relay protection in power system with rated frequency of 50Hz or 60Hz. The product conforms to iec60044-1; 2003 and GB1208-2006 standard.
The magnetic conducting material of Mr series current transformer is made of annealed annular iron core to ensure the accurate limit coefficient of product grade 5p5, 5p10 or 10p10; Ensure that the product is not saturated under the primary short circuit state, and effectively ensure the relay action. The coil is dipped in paint, which effectively prevents the product from being affected by moisture. Primary is P1 and P2; The secondary is 1S1 and 1S2; When the primary current flows from P1 to P2, the secondary current flows from S1 to S2 through the external circuit, i.e. to S2, i.e. to reduce the level.
Reminder: when the primary current passes through, the secondary circuit shall not be open circuit, otherwise high voltage will be generated.
- rated primary current: 30~5000a;
