Hello Ayekami,
The OV and the UV contact can be operated together if you have a phase failure. See attachment regards LesPaul Attachment3UG4.pdf (222 Downloads) |

Hi Paul, Thanks for your reply,you have responded against phase failure not for under voltage condition, your response against phase failure is noted and relay is working fine against phase failure as per the graph.Whereas our problem is relay is not working during UV condition as per the graph you sent . (OV contacts should not make). In addition, we have once again attached our test report for your review and during UV condition phase were not failure but only voltage level of the phase was below the setting voltage as mentioned in the test report and the test was carried out which phase voltage separately.
Waiting for your reply. AttachmentRelay Test report.pdf (225 Downloads) |
