1. main features:

It has comprehensive functions and can not only meet the test requirements of excitation characteristics (I. e. volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angular difference of various CT (e. g. protection, metering and TP), but also can be used to test excitation characteristics, transformation ratio, polarity and secondary winding resistance of PT electromagnetic units.

Automatically give CT and PT parameters such as inflection point voltage/current, 10%(5%) error curve, accurate limit coefficient (ALF), instrument security coefficient (FS), secondary time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance, etc.

• Test to meet the GB1208(IEC60044-1), GB16847(IEC60044-6), GB1207 and other types of transformer standards, and in accordance with the type and level of transformer automatic selection of which standard for testing.

• Based on the advanced low-frequency method test principle, it can cope with CT tests with inflection points up to 45KV.

• Friendly and beautiful interface, full Chinese graphical interface.

• The device can store 2000 sets of test data without losing power. After the test is completed, the U disk is stored in the PC, the data is analyzed by software, and the WORD report is generated.

The test is simple and convenient. CT direct resistance, excitation, ratio change and polarity tests are completed with one key. Besides load test, all other CT tests adopt the same connection mode.

• Easy to carry, device weight <9Kg.

Test wiring

Test wiring steps are as follows:

The first step: according to the description of CT test items described in Table 2.1, wire according to Figure 2.1 or Figure 2.2 (for CT of various structures, refer to the actual wiring method described in Annex D).

Table 2.1 Description of CT Test Items

Resistance	Excitation	transformation ratio	Load	Description	Wiring Diagram
√				Measuring the secondary winding resistance of CT	Fig. 2.1, but the primary side may not be connected
√	√			Measurement of secondary winding resistance and excitation characteristics of CT	Fig. 2.1, but the primary side may not be connected
√		√		Measure the secondary winding resistance of CT, and check the CT ratio and polarity	Figure 2.1
√	√	√		Measure the secondary winding resistance and excitation characteristics of CT, and check the CT ratio and polarity.	Figure 2.1
			√	Measuring the secondary load of CT	Figure 2.2

Step 2: The other windings of the same CT are open, and the primary side of the CT should be grounded, and the equipment should also be grounded.

Step 3: Turn on the power and prepare for parameter settings
