ctpt= current transformer & potential transformer

CT connected in series with the circuit & pt connected in
parallel to trivector meter

trivector meter is metering device which reads all
parameter of electrical devices like
KW,KVA,KVAR,KVARH,PF,I,V,etc

A separately excited dc motor having 2 ohm armature resistsance draws a current of 10A and torque developed is 20 Nm under rated field condtion. the speed of the motor under the rated field condtion , when it is connected to a 100V DC source and delivering 10Nm torque....
