3 terms and definitions
JB/T 6819.3 and GB/T 6148 and the following terms and definitions apply to this standard.
3.1 Resistance uniformity
The difference between the actual resistance value of any two segments of the same line and its average value. Resistance uniformity according to formula (1).
U = | Ra - Rb | (Ra Rb)/2 ×
100% (1)
Where.
U --- resistance uniformity;
Ra - a resistance value per meter of resistance line in ohms per meter (ohm/m);
Rb --- b segment resistance of the resistance per meter, in ohms per meter (ohm/m).
