1. Zero-sequence current transformer is to test the zero-sequence current. 2. Zero sequence current refers to the vector sum of three-phase currents. Under normal conditions, the sum is zero. 3. When the zero-sequence current is relatively large, it means that there...

What are the classification of current transformer?   Introduction:   Transformers are also widely used in life, but we don’t know much about them. Today, we will take you to know about current transformers, and have a look at the classification of current...

1. 11KV Current transformer ct for measurement(or the measuring winding of the current transformer) : it provides the current information of the power grid to the measuring and metering devices within the normal working current range. 2. Protection ct with power...

How does the epoxy resin current transformer go through the cable? The normal connection method of the 5p20 bushing ct goes through the core is that the primary wire enters from P1 into P2 and the secondary current flows out from S1 into S2. If you connect the first...

When the DC current transformer under test has analog voltage output, as an alternative of measuring error method, it can be tested by double-meter method. The output of the standard DC current comparator and the DC current transformer under test are defined according...

The field test of DC current transformer is helpful to find out the possible faults and hidden troubles of the measuring and monitoring equipment in the converter station.  It is of critical importance to ensure the safe and stable operation of the converter stations...
