AL304 Transformer spot test
Implementation of standards.
JJG169-1993、JJG314-1994
Main use and characteristics:
HGQL Transformer spot test, in the integral whole turn to rise to flow, rise to press under the match that the device makes choice of purchase an equipments, can carry on the electric current that the protection use with each other the characteristic of Fu Anne of feeling machine and 10% error margin curve test. Can measure with each other a feeling machine of ratio bad, the Cape differ and change to compare;
Technique index sign:
HGQL Transformer spot test, measure scope
Change to compare: the 5 As/5 A ～ 5000 As/5 As(the 5 As/1 A ～ 4000 As/1 A), The full circle compares an error margin:0.5%,
The CT measures an accurate degree to satisfy 0.05 classes.
Measure an error margin: Compare to differ 0.1 class Capes to differ 4 ′s, 20%, 100%, 120% sums settles electric current.
Measure an error margin: Compare to differ 0.05 classes, Cape to differ 2 ′s.
Electric voltage with each other the feeling machine measure scope, 2.2 kV ～ 132 kVs,
Measure an error margin: Compare to differ 0.5 classes.
Physically two burden test: The PT carries a 10 VA ～ 500 VAs,
Measure an error margin:2 classes, the CT carries 0.1 Ω～s 25 Ωs,
Measure an error margin:2 classes.
Fu Anne characteristic test, the electric current tests scope:0.1 A ～ 50 As,
Measure an error margin: One class.
The electric voltage tests scope: The 10 V ～ 1500 Vs measure an error margin:One class.
Work condition:
Power supply electric voltage: The AC 220 V ± is 10%,
Power supply frequency: The 50 Hz ± is 2%.
Environment temperature:0~40 ° Cs.
Environment degree of humidity:25 ° Cs<85%
