PROTECTION METHOD OF THREE-PHASE ELECTRICAL NETWORK WITH NEUTRAL WIRE FROM NON-SYMMETRICAL MODES |
| 摘要 |
FIELD: electricity. ^ SUBSTANCE: currents of phase conductors are passed through fuse strips of three fuses installed in electrical circuits of these wires; in addition, fuse strip of each fuse is heated with currents appearing on secondary windings of three intermediate current transformers attached to outputs of secondary windings of zero-sequence current transformer. ^ EFFECT: improving reliability and quick action of protection. ^ 2 dwg |
