Test connection

Used for selecting one or more experiment item, including four options such as resistance, excitation, ratio, burden etc. According to transformer type, four options can be combinated as shown in below table.

Table 2.1 CT experiment project description

experiment item				Description	Connection diagram
resistance	excitation	ratio	burden	Description	Connection diagram
√				Measure CT’s secondary winding resistance	Fig 2.1,can disconnection if measuring primary winding.
√	√			Measure CT’s secondary winding resistance and excitation characteristic	Fig 2.1,can disconnection if measuring primary winding.
√		√		Measure CT’s secondary winding resistance, check it’s ratio and polarity	Fig 2.1
√	√	√		Measure CT’s secondary winding resistance and excitation characteristic, check it’s ratio and polarity	Fig 2.1
			√	Measure CT’s secondary burden	Fig 2.2

Note：the ‘√’ means valid ,ａnd the blank means invalid

Step:

Step 1. According to the CT testing project description of the table 2.1 to wiring(For all the CT structures,please refer to the description of appendix D for the actual connection mode)

Step 2. The other windings of the same CT should be opened,CT’s primary side to grounding, equipment should be also to ground

Step 3. Power on and prepare parameters Settings.

Step 4. Then switch cursor to the “start" button to start
