What wattmeter indicate for blocked rotor test?
There is one thing that watt-meter indicates of blocked rotor test. That is the voltage flows and in blocked rotor test.
What are No Load And Blocked Rotor tests on a three phase induction motor?
There is no such thing as a "Blocked" Rotor test so that must be a misunderstanding of the correct description, which is "Locked" Rotor test.For more information see the answer to the Related Question shown below.

What does wattmeter indicate in blocked and no load test?
A water meter that says no load test means one thing. The thing that it means is iron loss.
What are No Load And Locked Rotor tests on a three phase induction motor?
Doing a No Load test of a 3-phase induction motor involves the measuring of current, voltage, torque etc with no load on the rotor shaft, meaning that it is free to turn but is not driving anything else. Similarly a Locked Rotor test involves the measuring of current, voltage, torque etc with the rotor shaft "locked" i.e. prevented from turning, which is the worst loading condition the motor would ever have to contend with.
Can an Ovulation Test still work if your tubes are blocked?
yes it will still work because the test does not detect the egg, it detects the LH hormone. the hormone that comes with ovulation.
What will happen if you stop the rotor and supply is continue in induction motor?
This is done under blocker rotor test of induction motor in which the rotor of the motor is stopped by some external mechanical means and the supply is increased slowly from the autotrasformer until the rated motor current is reached and the V , I ,W readings are taken . As the rated current flows the winding temperature increases but upto rated current this temperature rise is within the safe limits . In the blocked rotor condition the rated current is achieved at around 20-25% of the rated supply voltage . If we further increase the voltage then the current flowing is more than it's rated or permissible value so windings get dengerously hot and they get burnt or damaged .
Why locked rotor test is performed?
Electrical machines such as motors are designed to withstand a certain maximum rated current (continuous) and a fault condition current for a short duration only. In order to practically verify this capability, a locked rotor test is performed on the motor as part of the final factory acceptance test. The motor rotor is mechanically locked and rated current is applied to the stator winding incrementally, starting from zero, all at rated supply voltage and frequency. Motor stator winding temperature is monitored and also the shaft output torque can also be calculated, if a load cell or strain gauge is connected to the torque arm. Therefore this locked rotor test (which is equivalent of a short circuit test for a generator) is used to verify the maximum current handling capability of the motor. Anush GE
How did the baby form in the test tube?
The frozen egg is united with the sperm in the test tube , and then inserted in the uterus for the next nine months to develop.. This is done usually when the tubes are blocked.
Why is Webkinz blocked?
If it is blocked at home your parents blocked it, but if it is blocked at school the blocked it because it was a game.
