Current Transformer CT PT Tester, 110V/220V

Q1: What is a current transformer analyzer?
A1: Current transformer analyzer is a multi-functional field test instrument specially designed for testing voltammetric characteristics, ratio, polarity, error curve, inflection point calculation, and secondary side circuit check of transformers.

Q2: How to use the current transformer analyzer?
A2: In the experiment, just set the test voltage and current values, and the device can automatically boost voltage/flow, and can quickly display the volt-ampere characteristic curve of the transformer or the experimental results of the ratio and polarity, etc. It supports data saving and on-site printing. sisico current transformer analyzer not only eliminates the tedious labor of manual voltage regulation, manual recording, and curve drawing but also allows you to upload the test data to your computer through the USB interface on the computer for editing, saving, or printing. It is simple and convenient to operate and improves working efficiency.

Q3: How to judge the polarity of the current transformer?
A3: There are many ways to measure the polarity of current transformers, and we often use the following three test methods in our work: the DC method, the AC method, and the instrumentation method.

Tips: How to measure the polarity of CT?

• DC method
  
  Connect the positive terminal of the dry cell or battery to the primary winding P1 of the CT, and the negative terminal to P2. S1 of the secondary side 
  of the CT is connected to the positive terminal of the pointer ammeter (or the pointer multimeter to milliamp gear), and S2 is connected to the negative 
  terminal. After connecting the line, if the switch S in the moment of closing the pointer positive bias, pulling the instantaneous pointer reverse bias, 
  then P1, S1 is the same name end, the current transformer is minus polarity, such as the pointer swing with the above opposite for plus polarity.
  
  
• Instrumentation method
  
  The instrumentation method mainly uses a current transformer tester to determine the polarity of the CT, which adopts a constant voltage source 
  internally, has a wide measurement range, is easy to carry, and can not only visually display the CT polarity and ratio value, but also measure the 
  direct resistance and excitation characteristics of the CT, which is simple and intuitive, and is widely used at present.
