1. Phase angle error
2. Both ratio and phase angle errors
3. ratio error reduction in phase error is incidental
4. none of these
ratio error reduction in phase error is incidental
1. Increasing the exciting current
2. Increasing the resistance and leakage reactance in the transformer
3. By not employing turns compensation
4. None of these
None of these
1. For primary winding phase voltages above 100 KV
2. For keeping the value of transformation ratio constant irrespective of the burden by making certain adjustment
3. Because they are cheaper than the electromagnetic trans-formers above a certain voltage range
4. All of these
For keeping the value of transformation ratio constant irrespective of the burden by making certain adjustment
1. The same as that of power transformers of the same VA rating
2. Much greater than that of power transformers of the same VA rating because they are designed for low ratio and phase angle errors which require large sized cores and winding conductors
3. Smaller than that of power transformers of the same VA rating
4. None of these
None of these
1. High V/ohm ratings
2. High ohm/V ratings
3. Low meter resistance
4. High resolution
High ohm/V ratings
1. Using a bridge circuit
2. Using an electronic bridge compensator for nulling
3. Forcing a constant current and measuring the voltage across the unknown resistance
4. None of these
