ㆍUp to now OVR relays were separately set and also operated but they 11are compacted in one relay unit. So very convenient for handing too. ㆍAs assembled with state of art and multifunctions, it is most suitable 11and applicable to protective coordination. ㆍVolt meter being installed, it can be used for measuring ㆍElectronic indicator target accurately show the troubles and surely 11indicate electric trouble. |
