15、r escalator and moving walk power measurementsThis measurement may be run on request after commissioning and at any point during the equipment life cycle as needed. The specification for the measurement system is indicated in 4.1 for lifts and 5.1 for escalators and moving walks.3.3 Lift, escalator
16、and moving walk energy verification check3.3.1 GeneralThis check is to verify that power usage of a unit has not significantly changed over the life of the installation by a quick, simple procedure.DIN EN ISO 25745-1:2013-02 EN ISO 25745-1:2012 (E) 83.3.2 LiftOnly the current is measured, as this is
17、 the most likely element of energy consumption to change with equipment ageing. Initially a current or a current profile is established after equipment commissioning and after modernization. Thereafter checks may be performed at any time during the operating life of equipment, to determine whether t
18、he energy consumption of the equipment has changed. The specification for the measurement system is indicated in 4.1.Usually aging affects the energy consumption when the lift is running. Therefore unless modifications have been made it should only be necessary to measure the main current running.3.
19、3.3 Escalator and moving walkInitially power in the no load condition is measured. Thereafter, periodic checks of power in the no load condition may be performed at any time during the operating life of equipment, to determine whether the energy consumption of the equipment has changed. The specific
20、ation for the measurement system is indicated in 5.1.3.4 Multiple lift, escalator and moving walk installationsIn the case of multiple lift, escalator and moving walk installations, each unit is tested as a standalone piece of equipment.NOTE It is important to note that a group of lifts can be more
21、energy efficient than single units operating alone.4 Measurement procedures for a lift installation4.1 Preliminaries4.1.1 InstrumentationThe measuring instrumentation shall comply with the following:a) an ammeter and voltmeter capable of measuring root mean square values;b) an energy meter capable o
