|There is a risk of condensation when air around KT /KH conductors is cooling.
For example, for humidity = 50% and ambient temperature at 50°C around working conductors. When the power disappears, the ambient temperature will be <37°C, and the humidity in the air starts to condense. This is called : dew point.
From 37°C to 4°C (ambient temperature), the condensation will increase:
- During this time:
In conclusion :
- when KT or KH are running without any turn off, there is a thermal balance, therefore no condensation means no risk.
- If busway must be turned off for long time, it's necessary to have a security process before re-starting :
check for the prescence of humidity, if yes, carry out preventive drying and check the insulating resistances (IEC 60439-1 & 8.3.4)for further assistance regarding insulating test , starting after water damage please contact the Canalis technical team on 0870 608 8 608
