Photocoupler

The transformer comprehensive tester can be tested with complete items, as follows:

Current transformer test project:

1) Ratio measurement of current transformer

2) Polarity discrimination of current transformer

3) Secondary DC resistance measurement of current transformer

4) Measurement of volt-ampere characteristics of current Transformers - protection windings

5) 5% or 10% error of current transformer - protection winding

6) Measurement of the actual load of the current transformer

Voltage transformer test project:

1) Voltage transformer ratio measurement of voltage transformer

2) Polarity discrimination of voltage transformer

3) No-load error of voltage transformer

4) Measurement of the actual load of the voltage transformer

5) Voltammetric experiment

The product has the following characteristics:

l Automatic test: fast, simple and convenient. The power supply 380AC and 220AC automatically calculate the inflection point voltage and current and compound error automatically, and visually judge whether the transformer is qualified. It can fully test the volt-ampere characteristic curve, eliminating the cumbersome labor such as manual pressure regulation, manual recording, finishing, and drawing curve; it is easy to master without special training.

l Full-featured: Tests protection CT volt-ampere characteristics, 5% and 10% error curves, direct resistance, ratio, polarity.

1) The instrument can qualitatively measure the voltage transformer: when measuring, the instrument adds a certain power frequency voltage to the primary side of the voltage transformer, and can measure the primary voltage and the secondary induced voltage, and obtain the voltage transformer. The ratio and polarity at this voltage and the ability to perform volt-ampere characteristics experiments on voltage transformers.

2) The instrument can measure the on-site secondary load of the current and voltage transformers, and can measure the difference and angular difference of the current transformer under the load.

l Comes with a large-screen graphic LCD, full Chinese graphic surface: clear and beautiful, intuitive and convenient. The test shows the volt-ampere curve directly, with its own thermal printer, which can quickly print the graph and test data; it can also store the test data at any time.

l Strong scalability:

a) It can be tested by an external voltage regulator: if the output voltage and current of the single unit of the device cannot meet the requirements, the user-supplied voltage regulator can also be connected to the device for testing. The external voltage regulator test wiring and test method is very simple.

b) Optional external booster: The optional external booster can be up to 2000V, 3A, and the external booster can be used to test the volt-ampere characteristics of the 5000/1 class current transformer.

l With storage and printing functions, each setting parameter can be saved after power down.
