The master wattmeter showed no change in the total city load.
Watch that wattmeter: It looks as though early estimates of China's future power demands were a tad conservative.
Two-wattmeter method use: unequal phase loading, non-accessible PEN-conductor; measuring instruments of the same type have to be used result: total power = P1 + P2, when P1 P2, the total power = P1 -
Three-wattmeter method use: unequal phase loading, accessible PEN-conductor result: total power = P1 + P2 +
Single wattmeter method use: equal phase loading, accessible PEN-conductor result: total power = 3 × measuring result
