On the other hand, measured values are part of a statistical distribution that can be specified by an interval with upper and lower limits and a probability for measured values to lie within this interval. Unless otherwise stated (e.g. “100 % tested”), the LEM definition for such intervals designated with “min” and “max” is that the probability for values of samples to lie in this interval is 99.73 %. For a normal (Gaussian) distribution, this corresponds to an interval between −3 sigma and +3 sigma. If “typical” values are not obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to an interval between −sigma and +sigma for a normal distribution. Typical, maximal and minimal values are determined during the initial characterization of the product.

V and TA = 25 °C 0.12 aver. + 3σ 0.10 0.08 ℇtot (% IP N) The transducer is sensitive to the primary current linkage ΘP (also called ampere-turns). ΘP = NP · IP Where NP is the number of primary turn (depending on the connection of the primary jumpers). Caution: As most applications will use the transducer with only one single primary turn (NP = 1), much of this datasheet is written in terms of primary current instead of current linkages. However, the ampere-turns (A) unit is used to emphasis that current linkages are intended and applicable. IO M (max) / IP N 0.06 = 0.04 IO E (max) / IP N 0.02 0.00 Simplified transducer model The static model of the transducer with current output at temperature TA is: Iout = S · ΘP · (1 + ε) In which (referred to primary): ε · ΘP = IO E + IO T + εS · ΘP + εS T · ΘP + εL(ΘP max) · ΘP max + IO M -0.02 -1 -0.5 0 0.5 IP / (KOL · IP N) with KOL = 1 ... 10 1 Figure 3: Total error εtot Electrical offset referred to primary ΘP = NP · IP : primary current linkage (A) ΘP max : maximum primary current linkage applied to the transducer Iout : Output current (A) S : sensitivity of the transducer TA : ambient operating temperature (°C) IO E : electrical offset current (A) IO M : magnetic offset current (A) IO T : temperature variation of IO E (A) εS : sensitivity error at 25 °C εS T : thermal drift of S εL(ΘP max) : linearity error for ΘP max Using the current cycle shown in figure 3, the electrical offset current IO E is the residual output referred to primary when the input current is zero. This model is valid for primary ampere-turns ΘP between −ΘP max and +ΘP max only. This is the absolute maximum error. As all errors are independent, a more realistic way to calculate the error would be to use the following formula: The magnetic offset current IO M is the consequence of a current on the primary side (“memory effect” of the transducer’s ferromagnetic parts). It is measured using the following primary current cycle. IO M depends on the current value IP ≥ IP N. Magnetic offset referred to primary Primary current cycle i =1 Total error referred to primary The total error εtot is the error at ±IP N, relative to the rated value IP N. It includes all errors mentioned above ● the electrical offset IO E with KOL = 1 .. 10 1 ∑ε i2 0 -1 1 2 3 4 5 Step ● the sensitivity error εS ● the linearity error εL (to IP N). 2 I O T (T ) = I O E (T ) − I O E ( 25 °C ) N ● the magnetic offset IO M IP (3) + IP (5) The temperature variation IO T of the electrical offset current IO E is the variation of the electrical offset from 25 °C to the considered temperature.

The sensitivity S is defined as the slope of the linear regression line for a cycle between ±IP N. The linearity error εL is the maximum positive or negative difference between the measured points and the linear regression line, expressed in % of IP N. Delay times The delay time tD 10 @ 10 % and the delay time tD 90 @ 90 % with respect to the primary are shown in the next figure. Both slightly depend on the primary current di/dt. They are measured at nominal current. I 100 % 90 % IS IP tD 90 10 % tD 10 t Figure 5: tD 10 (delay time @ 10 %) and tD 90 (delay time @ 90 %).
