BS ISO 8102-1:2020 pdf free.Electrical requirements for lifts,escal ators and moving walks.
The electromagnetic emission levels at each machine/motor port (conductive) of the apparatus/assembly of apparatus shall not exceed the limits specified in Table 3. If shielded connectors and shielded cables, in accordance with the apparatus/assembly of the apparatus manufacturer’s specifications, are used for machine/motor ports, or the cables are less than or equal to 2 m long, measurements at those ports are not necessary.The requirements of IEC 61000-3-11 apply to a system. Voltage fluctuations are dependent on the impedance of the mains supply for an individual system and the characteristics of the apparatus/assembly of apparatus. The manufacturer shall document the maximum impedance of the electricity mains supply for the system.Apparatus/assembly of apparatus using controlled speed drives are known not to be a cause of voltage flicker disturbance. However, direct on line or star-delta starting of escalator motors, hoisting and hydraulic pump motors and repetitive direct switching of highly inductive loads (e.g. transformer) should be treated with caution.The limits of Tables 4 to 6 apply to a balanced three-phase system (equipment) or a hybrid system (equipment) in one of the following circumstances: a) hybrid equipment having a maximum third harmonic current of less than 5 % of the reference current; or b) there is provision in the construction of hybrid equipment to separate the balanced three-phase and the single-phase or interphase loads for the measurement of supply currents, and when the current is being measured, the part of the equipment being measured draws the same current as under normal operating conditions. In that case, the relevant limits shall be applied separately to the single-phase or interphase part and to the balanced three-phase part. Table 4, Table 5 or Table 6 applies to the current of the balanced three-phase part, even if the rated current of the balanced three-phase part is less than or equal to 16 A per phase. Table 7 applies to the current of the single-phase or interphase part but, if the rated current of the single-phase or interphase part is less than or equal to 16 A, the relevant limits of IEC 61000-3-2 to the single-phase or interphase part can be applied instead of the limits stated in Table 7.BS ISO 8102-1 pdf download.
