The sensors shall perform correctly when returned to initial working conditions. 4.3.3.1.4 Response time (ts,r) Sensors for DC measurement shall have a maximum response time of 10 ms. If the DC sensor is to be
31、used in a system where the energy content associated with harmonics is significant, a shorter response time can be appropriate. 4.3.3.1.5 Bandwidth requirements for electronic sensors The supplier shall provide a curve showing the variation in performance of the sensor for variation in frequency.

For a sensor with digital output, the supplier shall specify the maximum frequency (fa) which can be measured without aliasing. For sensors with a digital output, fa is usually half the sampling frequency used. NOTE 2 T

BS EN 504632:2017EN 50463-2:2017 (E) 25 For electronic sensors, the supplier shall indicate the type of current limiting measures used (if any). For electron
36、ic sensors, the supplier shall specify any time delay between removal of the short circuit and the outputs returning to within specified accuracy limits. The time delay shall not exceed 5 s. Fault protection for electronic sensors shall be provided in accordance with EN 50155:2017, 7.2.3. 4.3.3.3 Li

38、following conditions: continuous operation at Umax2 and at the rated frequency; maximum applicable ambient temperature of the temperature class selected in accordance with environmental requirements of EN 50463-1:2017, 4.3.6.3; output conditions which create the highest temperatures in the sensor; i

42、 effects of temperature variation, shall not exceed the values given in Table 5. In order to be able to achieve compliance with the maximum error limits specified in Table 5, a VMF of a given class can have its maximum error at reference temperature constrained to a value lower than the maximum allo
43、wed by the accuracy class as specified in Table 4. If this is the case, the supplier shall declare this lower maximum error limit at reference temperature and give evidence to demonstrate this lower limit will ensure the maximum limits given in Table 5 are not exceeded.
