Method of Statement (Mechanical & Electrical)

Introduction:  This manual gives a brief description of state-of-the-art technologies used to develop high efficiency motors, including premium efficiency induction motors, permanent magnet motors, and switched reluctance motors. It also analyses issues that affect motor system efficiency and provides guidelines on how to deal with those issues namely by:  Selection of energy‐efficient motors  Properly sizing of motors;  Using Variable Speed Drives (VSDs), where appropriate. The use of VSDs can lead to better process control, less wear in the mechanical equipment, less acoustical noise, and significant energy savings;  Optimisation of the complete system, including, the distribution network, power quality and efficient transmissions;  Motor Systems Energy Assessments  Taking Measurements  Applying best maintenance practices.  Motor Repair  How to win approval for energy efficiency projects  Energy Management Systems

Summary ITU-T Recommendation L.77 describes methods to install optical cables inside sewer ducts, which applies to both the cable installation and the pre-installation of an infrastructure, if requested. This Recommendation covers both man- and non-man-accessible sewer ducts. This Recommendation is not intended to address all of the safety concerns, if any, associated with its use. Therefore, it shall be the responsibility of the user of this Recommendation to establish appropriate health and safety practices and determine the applicability of regulatory limitations, if any, prior to its use.
