Product Description
 
Introduction:
 
This device is used to measure CT with primary accuracy during 0.01~10 and rated secondary current during 1mA to 99mA.
 
It no need to switch the range within the scope of 2%~500% of the rated current, which means it can test errors under 5 times rated current.
 
During the testing, it could test at any time active component and reactive component of the tested instrument transformer secondary circuit impedance.
 
It auto indicate polarity, when there is polarity error it can auto cut the differential circuit, and make sound and Light alarm to ensure instrument safety
 
Self-checking function within the 2%--500% of rated current
 
It can work as rectangular coordinate system AC potentiometer to test AC small current
 
Can use integral method or component method to make periodic examination
 
Technique parameters
 
1.Measuring range and resolution
Measuring itemMeasuring rangeresolution
Instrument transformerRatio error ()±0.001 - 199.910-6
Angle error (min)±0.01 - 9000.01
2.Basic error:
   In-phase component and quadrature component value allowable error:=±(X·2%+1d)
   X - reading value, 1d - quantization error
2. In phase component and quadrature component phase error: 0.02 radians
Remark: when the instrument is not at the rated current, the testing display error and phase error are allowed to be two times the above
3. Other technique data:
1). Tested instrument transformer rated secondary current: 1mA--99mA, step count 1mA
2). Working current percentage accuracy ±1.5%, working scope: 2%--500%, maximum working current 500mA
3). Load impedance generated by two-stage current transformer secondary side: 10Ω
4). Polarity indication action current: < 30% of the rated working current
5). Load box resistance: 5Ω,10Ω,15Ω,20Ω,25Ω,50Ω,60Ω,75Ω,100Ω,300Ω(can be externally supplied)
6). Power dissipation: < 20VA
7). Dimension(mm): 460X380X160
8). Weight: < 12kg
