The test is conducted on the high-voltage (HV) side of the transformer where the low-voltage (LV) side (or the secondary) is short-circuited.A wattmeter is connected to the primary side. An ammeter is connected in series with the primary winding. A voltmeter is optional since the applied voltage is the same as the voltmeter reading. Now with the …
Splet#Transformers #Shorts #Autobots #Primes #The13 SpletShort circuit or Impedance test on Transformer The connection diagram for short circuit test or impedance test on transformer is as shown in the figure below. The LV side of transformer is short circuited and wattmeter (W), voltmere (V) and ammeter (A) are connected on the HV side of the transformer.
SpletThe purpose of conducting a short circuit test is to determine the winding resistance, reactance, and the copper loss of the transformer. Circuit for short circuit test For convenience a variable voltage source is connected to the HV side of the transformer and the LV side of the transformer is short circuited.
This type of transformer fault is caused due to the winding turns flashover by line surges. When a number of turns in the same winding short circuit. A decrease in the terminal current occurs.
