"That’s not in the textbook," Sen finished. "Correct. Now, do you know which feeder serves the water pumping station?" principles.of.power.system.-.v.k.mehta.

"The Indrapur line is drawing 10% above rated capacity," Rohan said, tapping a gauge. "If the tea garden load kicks in at 6 AM, the voltage drop will be critical. Mehta says—"

"Then shed Feeder 7. Send a runner to the tea gardens—tell them to start their diesel now. We’ll buy ten minutes. In ten minutes, the city’s morning shift will start, and their induction motors will draw starting current. That’s your real problem. Not the line overload. The starting current." "Then don't trip," Sen said

"Mehta’s coordination assumes you have spinning reserve. We don't. The backup diesel at the tea factory hasn't run in six months. If you trip that line now, the sudden loss of load will cause a frequency rise on the main bus. That will trip the over-frequency relay on the solar farm. Then the city hospital loses its backup. Then—"

"Does the village downstream have overhead tanks?" "Correct

"Wait," Sen said, his voice suddenly sharp. "Look at the frequency meter."
