MS IEC 61724:2010 (CONFIRMED:2015)
Status : 1st Confirmation
Format : PDF

This Malaysian Standard recommends procedures for the monitoring of energy-related PV system characteristics such as in-plane irradiance, array output, storage input and output and power conditioner i ....Read more nput and output; and for the exchange and analysis of monitored data. The purpose of these procedures is to assess the overall performance of PV systems configured as stand-alone or utility grid-connected, or as hybridised with non-PV power sources such as engine generators and wind turbines.

This Malaysian Standard may not be applicable to small stand-alone systems due to the relatively high cost of the measurement equipment. Close

Format : PDF

This Malaysian Standard specifies the procedure for evaluation of the risk of damage to a structure caused by direct and indirect lightning flashes, and to permit the bodies concerned to fix an accept ....Read more able value for the frequency of damage to structures. Once an upper limit for the frequency of damage has been fixed, the procedure given allows for the selection of appropriate protective measures for the structure. 

NOTE — Damage to the equipment due to direct magnetic coupling with lightning current which strikes the earth nearby the structure may be usually disregarded. Where sensitive electronic equipment are installed in the structure, this damage should be also taken into account in the assessment of the risk. Close
