OF PAPER The paper describes the conditions on the system in Toledo which was originally delta-connected. Serious trouble was experienced when a short circuit occurred especially with synchronous apparatus connected to the line which invariably failed due to the voltage drop occasioned by the severe short circuits on the delta system. This trouble was overcome by changing the transmission to a Y system with the neutral grounded. The effect of a short circuit with the new connection has beendoi:10.1109/t-aiee.1919.4765622 fatcat:qhuif3iqprefnjccjjmjnbdyka
