50Hz vane relay phase sensitivity of drop-voltage tests characterisation of type VT1, CE391 and G4 relays (RR-SAM-014)

This is a follow on report from Report No. RR SAM 004 which is on the same subject and should be read in conjunction with it. Previously a sample of 50Hz vane relays were tested in terms of their pick-up voltage sensitivity to phase. This report considers the drop-away voltage...
