What is PD IEC/TR 61000-3-7 - EMC limits for MV, HV and EHV about?
PD IEC/TR 61000-3-7 provides guidance on principles that are used as the basis for determining the requirements for the connection of fluctuating installations to MV, HV and EHV public power systems.
The primary objective of PD IEC/TR 61000-3-7 is to provide guidance to system operators and owners on engineering practices, that facilitates the provision of adequate service quality for all connected end-users. PD IEC/TR 61000-3-7 addresses the allocation of the capacity of the system to absorb disturbances.
PD IEC/TR 61000-3-7 gives guidance for the co-ordination of the flicker emissions between different voltage levels to meet the compatibility levels at the point of utilisation.
Note: In addressing installations, PD IEC/TR 61000-3-7 is not intended to replace equipment standards for emission limits.

Why should you use PD IEC/TR 61000-3-7 - EMC limits for MV, HV and EHV?
Electromagnetic compatibility (EMC) is the ability of an equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.
PD IEC/TR 61000-3-7 is a part of the IEC 61000 series and addresses emission limits and immunity limits. PD IEC/TR 61000-3-7 provides guidance on emission, emission level and emission limit. PD IEC/TR 61000-3-7 is about setting emission limits of fluctuating installations that depends on the agreed power of the end-user, the power of the flicker generating equipment, and the system characteristics.
PD IEC/TR 61000-3-7 also provides guidance on the immunity level which is described as the maximum level of a given electromagnetic disturbance on a particular device, equipment, or system for which it is capable of operating with a declared degree of performance. PD IEC/TR 61000-3-7 aids the fluctuating installation. PD IEC/TR 61000-3-7 recommends the coordination approach that relies on individual emission levels being derived from the planning levels so that overall EMC is maintained.
PD IEC/TR 61000-3-7 helps to limit the flicker injection from the total of all fluctuating installations to levels that do not result in n flicker levels that exceed the planning levels. PD IEC/TR 61000-3-7 aids in the smooth functioning of power systems
