UIE International Flickmeter. Application to the Measurement of Disturbances Caused by Arc Furnaces and Electric Welders. Session 2.2C N.2.2.17

摘要

ENEL has developed a flickermeter that complies with the specifications established by the UIE Disturbances Study Committee. The paper contains a description of the instrument and of field tests carried out on different types of arc furnace and electric welder which are among the appliances that produce the most disturbing flicker. In the course of the measurements, consideration was given to the problem of simultaneity (i.e., the simultaneous presence of several disturbing loads in the same network). The experimental results are compared with those of the calculation method suggested in international standards. The report considers the problem of striking a balance between different interests, which means reducing to a minimum the costs born by the distributor to reinforce the network, as well as those sustained by the manufacturers and users of electroheat equipment.
