| Abstract: |
| It is necessary to test converter using normal measuring instruments during speed re-gulation system fault.Several instruments are introduced:magnetoelectric type,rectifier type,electro-magnetic type and electrodynamic type.Their measuring methods and cautions are brought forward,and the technical essentials of voltage /current measuring for converter are offered.Furthermore,the insulation resistance measuring of converter and its external circuits are introduced,as well as the test of rectifier bridge and converter bridge.It helps to detect and remove system fault. |
