No load current of transformer is non sinusoidal even though sinusoidal voltage is provided in oc sc test?
eddy current loss in the transformer core is reduced by
Why sumpners test is called heatrun test?
The temperature rise is not considered in OC & SC tests of transformers.. But in Sumpner's test, temp. rise is considered.. Hence is called "Heat-run test".. Also, the transformers draw only the power req. to supply core & Cu. losses of transformer..
How armature resistance can be determined in a synchronous generator?
synchronous impedance can be calculated by performing oc test and sc test. by oc test,since the armature current is zero Vt=Ef . in short circuit test ,entire emf is consumed in circulating the short circuit current Isc,through the synchronous impedance. Zs=Ef/Isc.= (open ckt. terminal voltage for a certain field current)/(short ckt. current at the same field current)
Why UPF wattmeter is used in SC test?
UPF(Unity Power Factor) is connected as the power factor is 1. Unlike OC where quantum dynamic rules apply in SC the time space gravitational lensing takes place which is why only LPF can be used.
What is the breakdown voltage of 1N4007 diode?
The reverse breakdown voltage of the 1N4007 diode is 1000 volts.
What is the difference between the performance values obtained from load test and sc and oc tests?
During load test the readings/performance could be monitored during load variation from zero 100% and short circuit.
Why are oc and sc tests preferred when compared to sumpners test?
OC and SC tests are used for predetermining the efficiency and % voltage regulation. It is more efficient test for a transformer than sumpner's test for 2 reasons. 1. two identical transformers are readily not available 2. two separate power supplies are required for the sumpner's test, whereas OC and SC are simple and best

How many forward castes are there in andhra pradesh?

What is the purpose of conducting sc and oc test of single phase transformer?
to determine the transformer characteristics...
Why oc test done in lv side?
In OC test , the equipments are connected in LV side since we need to get rated voltage . if it is cinnected in HV side the value of voltage will be less and current wil be more.Hence the ordinary instruments cannot measure this value of current
What is the density of nitrogen compared to breathable air?
The density of nitrogen is 1,2504 g/L.The density of air is 1,2922 g/L.Both values are at 20 oC.
What does the 'OC' stand for in OC ReMix?
overclocked
What is OC 192?
OC-n / OC-xxx indicates Optical Carrier signals which are carried over a SONET (Synchronous Optical Network) fiber optical network. The numbers after OC indicate various levels or data rates in the SONET hierarchy. Hierarchy goes like OC-1, OC3, OC-12, OC-24, OC-48, OC-96, OC-192 and OC-768 OC-1 is a SONET line with transmission speeds of 51.84 Mbit/s. OC-192 has a speed of 9953.28 Mbit/s (almost 10Gbps, so also called SONET 10G). You can get more details in SONET literature. - Neeraj Sharma
