What is current transformer burden?
What is current transformer burden? In a current transformer (CT), burden refers to the total impedance (resistance and reactance) presented to the CT’s secondary winding by the connected measuring device (such as an ammeter, relay, or meter). It is typically expressed in volt-amperes (VA) ...

Adverse Consequences of Secondary Short Circuit of Voltage Transformer
I. Adverse Consequences of Secondary Short Circuit of Voltage Transformer Adverse consequences: If the secondary side of the voltage transformer is short-circuited, a very high short-circuit current will be generated, which may damage the transformer and even affect the safe operation of the prim...

Why can’t transformers operate with direct current?
Why can’t transformers operate with direct current? A transformer cannot operate with direct current (DC) because its operation relies on a changing magnetic field, which DC does not provide. Here’s a detailed explanation of why transformers are ineffective with DC: 1. Operating Princ...

Why do we need reactive power compensation?
Why do we need reactive power compensation? And its principles and forms! Power factor is measured for different loads. In the previous era of direct current, there was no such thing as power factor. At that time, the power factor was 1. Later, Tesla brought us into the era of alternating current...
