② Portable Type and Fixed Type of Tester, carry out the test at anytime in anywhere for production or maintenance filed of PT and CT. (Factory and Labaratories too)
③ Touch Screen and low output voltage maxmizes the user's safety and convenience as per the below functions.
* "PORTABLE CURRENT TRANSFORMER OF EXCITING CURRENT AND CORE CHARACTERISTICS TESTER" IS PATENT REGISTERED: 2020. 11. 11.
* RATIO ERROR TESTER (PLC + HMI FUCTION) IS PATENT REGISTERED: 2020. 12. 10.
PT/CT Measurement Function
① It Includes all the functions in PT Ratio Error Tester. Also it can measure Pierce Type and Coil Type (Including Single Phase and 3 Phase)
Exciting Current Test
① Measure Exciting Current Value of CT by adding Simple Type of Exciting Current Tester. Safe and Fast Measurement (2nd Current1A, 5A)
② Guarantee safe Measturement for Max Power Test Voltage (Below AC 50V).
③ Provide all types of PT, CT Wiring Diagram for Test Purpose.
Ratio Measurement Range
① PT: 1~225(110V/110V~24750/110V, 220V/220V~49500V/220V)
② ACCURACY: ±0.5% of Ratio
③ CT: Coil Type 1~ 4000 × T (T = Test lead's Turn number, Max 2 Times)
④ ACCURACY: ±0.5% of Ratio

CT RATIO TEST CHARACTERISTICS
① CT RATIO TEST, based on it's own data - carry out automatic selection of secondary Circuit, which exciting Current is not overloaded by calculating the suitable data following by Set Parameter (PRI.A/ SEC.A, BURDEN, CLASS).
② "Pierce CT Type Test" can increase the measurement accuracy of Ratio Range by using Probe (Inside 5 UTRN)
③ It can increase the accuracy of "Non Burden ratio Error" by applying "Correction value of OFF-SET"
* Example:Display 60 Ratio after input 0.387 in Offset Value to adjust Ratioa vlaue in T Column.
