This is a class of current Transformers, and is a fairly low class. This has to do with what kind of burden can be placed on the secondary. A general rule is a C200 current transformer can supply ~200 volts at full ratio to its' secondary. If the burden (the CT resistance + cable resistance + relay or instrument resistance) times the maximum expected current is higher than 200 volts, the CT is likely to saturate.
During multiple fault events, a CT may keep some magnetizing current causing CT saturation to be higher on a reclose event. Typically CT's are sized and their ratios are chosen to minimize saturation when feasible.
What else can I help you with?
Eddy current in transformer?
Yes, a transformer has eddy currents.
What is the function of the primary current when the secondary winding of the transformer is open?
When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
What is mean by magnetizing current of transformer?
A: As current flow in the primary it will magnetize the core of the iron in the transformer that is called magnetizing.
How many amps does a 600 watt low voltage transformer box pull?
The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.
When current transformer is overloaded?
when your current transformer is over loaded make sure it turns back into a car and drives away
