2. CABLE CROSS BONDING CONNECTION
DRAWING
When current is flow through the cable a induced current will develop in the cable sheaths. This induced current will oppose the cable current. The cross bonding connection is used to neutralized the induced current. The cross bonding connection is explained in the above drawing. Cable sheath is terminate in various places and connected as cross connection 'R' sheath to "Y" sheath and 'B' sheath to 'R' sheath through resistors. Three phase voltage is applied in one end of cable and other end of cable is grounded. Short circuit current will flow through the cable and induced current in sheath will be measured by clam meter. If the current is zero in all three phase and cross connection ok .
