This part of IEC 62586 specifies product and performance requirements for instruments whose functions include measuring@ recording and possibly monitoring power quality parameters in power supply systems@ and whose measuring methods (class A or class S) are defined in IEC 61000-4-30. These requirements are applicable in single@ dual- (split phase) and 3-phase a.c. power supply systems at 50 Hz or 60 Hz. These instruments can be used: ?C in the generation@ transmission and distribution of electricity@ for example inside a power station@ substation or a distributed generator connection. ?C at the interface point between the installation and the network@ e.g. in order to check the compliance of the connection agreement between a network operator and the customer. NOTE 1 These instruments can also be used for other applications@ e.g. inside commercial / industrial installations especially where comparable measurements are needed (i.e. data centers or petrochemical plants). These instruments are fixed-installed or portable. They are intended to be used indoors and/or outdoors. Devices such as digital fault recorders@ energy/power meters@ protection relays or circuit breakers may include power quality functions defined in 61000-4-30 class A or class S. If such devices are specified according to this standard@ then this standard fully applies and applies in addition to the relevant product standard. This standard does not replace the relevant product standard. NOTE 2 It is not the intent of this standard to address user interface or topics unrelated to device measurement performance. NOTE 3 The standard does not cover post-processing and interpretation of the data@ for example with a dedicated software.
