Question 579Electricity & Electronics - Assistant Engineer

The correct answer is A) The kilowatt meter of No.1 SSDG would indicate a negative wattage (a reversed reading). Explanation: 1. When a generator is operating in parallel with another generator and begins to motorize (run as a motor instead of a generator), the kilowatt meter on that generator will show a negative reading. This indicates that the generator is consuming power instead of producing it, which is a sign that it has started to motorize. 2. The reverse power relay is designed to trip the generator offline when it starts to motorize to prevent damage. However, if the reverse power relay fails to trip the generator, the negative kilowatt reading on the meter would be the indication that the generator is motorizing. 3. Options B and C are incorrect because the ammeter would show a higher current, and the power factor would remain at unity, but these are not the primary indications of the generator motorizing.
