Many times when an induction furnace is partially or completely full of liquid metal and there is power disruption, breakdown or GLD tripping there may be risk of metal leakage.
The team at the site is unaware of the status of the earth leakage as the furnace is in the power-off condition. In addition, the standard earth leakage system is for an entire circuit which may give rise to some leakage current that may not be related to metal leakage and may cause nuisance tripping. This causes confusion and creates risk when the furnace has to be restarted.
To address this, Megatherm has launched Lining Health Detection System. This system indicates earth leakage/lining health data specific to the crucible when the furnace is in off condition or test mode. Now, in case of any breakdown or tripping the site team will know whether it is safe to restart the furnace. This system activates automatically and PLC records data of entire patching cycles to create a database for future reference
ONB-ELD or Online Bottom Earth Leakage Detection system works along with the standard GLD system while the furnace is “Online”
It gives a percentage reading of bottom earth leakage only
It is not affected by leakage current in the tank circuit
Bottom earth leakage reading is displayed in HMI along with standard GLD reading and together with Lining Health Detection it forms a robust accident prevention system
