(continued)
Fig.25 Insulation test - Secondary circuit / earth
3rd test: Secondary circuit / earth
- Place a test-prod against one of the
welding sockets (e.g.
(Fig.25)
- Place the second test-prod against the
protective contact of the mains plug
(Fig.25)
- Carry out the measurement
- Insulation resistance must be > 2.5
MOhm
If the insulation resistance is less than 2.5
MOhm, the power source must be
inspected and repaired
- Main focus of test: Transformer,
