HGQH(12)-C Current Transformer Test System CT PT Testing Bench
HGQH(12)-C CT PT Testing Bench
The HGQH(12)-C is a new-generation CT and PT calibrating device that offers faster and more accurate performance. It was developed to meet the demands of modern calibration. Building on the proven features of its predecessor, this device incorporates significant improvements. With flexible configuration for a wide range of load cases and transformers, it delivers excellent performance in rapid testing and precise point location during CT testing.
Specific instructions for each part are as follows.
Working Condition:
Measuring Range:
In-phase component(%):0.0001~200.0 Resolution: 0.0001
Orthogonal Component (min):0.001~ 999.9 Resolution: 0.001
Impedance(Ω):0.0001~60.0 Resolution:0.0001
Admittance(ms):0.0001~60.0 Resolution:0.0001
Basic Error:
In-phase Component: ΔX=±(X×2%+Y×2%)±Dx (with Class 1 to spare)
Orthogonal Component (with Class 1 to spare)
"X","Y"--Values Displayed
"Dx, Dy"--Quantified Error Dx=2, Dy=5
(4)Percentage: Class 2 (with Class 1 to spare)
Working Range:
Current:(1%－149%)In (In =5A)
(5%－149%)In (In =1A)
(2) Voltage:(5%－149%)Un (Un =100V, 100V/ √3V)
(5%－200%)Un (Un =100V/3)
(3) Voltage: (5%－200%)Un (Un =110V, 110/ √3V)
Work Load:
(1) Current: TO to TX＜0.12Ω cosΦ=1.0
(2) Voltage: a to x＜0.25VA (100V)
Main Features of the Calibrator
(1) Application of 320×240 LCD, broad vision, long life self lighting, making it convenient to operate.
(2) All English interfaces, simple and nice.
(3) Extra-large display of percentage, ratio error and phase error, easy to observe.
(4) Automatic sampling, rightly meet the need of JJG314-1993 and JJG314-1994.
(5) Automatic identification of polarity fault and ratio error mistake.
(6) Software can be upgraded with time.
(7) Completely solve the testing problems that Class S encounters.
(8) Automatic switch of measuring range.
(9) Perfect combination of advanced circuit technique and DSP; ultimately avoid the instability of the impedance phase differential circuit.
(10) Power consumption:
<15VA (with micro-printer)
<25VA (without micro-printer)
(11) Harmonic Suppression Ratio: >40db
