Replacement:
This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled safety isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz, the rated output not exceeding: - 10 kVA for single-phase transformers; - 16 kVA for polyphase transformers.

Abstract: Specifies requirements for the installation of vented secondary batteries permanently installed in buildings.
Scope:

Scope:
This standard defines the method for determining load unbalance emission limits for customers connecting to, or requesting connection to BC Hydro's public medium-voltage (MV) distribution network. It also describes the assessment process for verifying compliance with prescribed load unbalance emission limits.
Application:
Q4 is intended for application by distribution planning engineers, regionalengineers, designers and power quality engineers for:

This project aims at the standardization of the microgrid design and planning process, the technical requirement specification of microgrid design and the evaluation of the microgrid planning scheme. The implementation of the proposed recommended practice will enhance the safe, reliable and economic operation of microgrid.
