Energy Efficiency

IEC 62282-6-200 specifies test methods for the performance evaluation of micro fuel cell power systems for laptop computers, mobile phones, personal digital assistants (PDAs), cordless home appliances, TV broadcast cameras, autonomous robots, etc. This new edition includes the following significant technical changes with respect to the previous edition:
- deletion of 5.3 (Fuel consumption test) as it was impractical to measure the actual consumption rate of some kinds of fuels;
- addition and modification of some terms and definitions.

IEC 62282-3-201 provides test methods for the electrical, thermal and environmental performance of small stationary fuel cell power systems that meet the following criteria:
- rated electric power output of less than 10 kW;
- grid-connected/independent operation or stand-alone operation with single-phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding 1 500 V;
- maximum allowable working pressure of less than 0,1 MPa (gauge) for the fuel and oxidant passages;
- gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.);
- air as oxidant.
This document describes type tests and their test methods only. This document covers fuel cell power systems whose primary purpose is the production of electric power.
This new edition includes the following significant technical changes with respect to the previous edition: revision of test set-up, revision of measurement instruments, introduction of ramp-up test, introduction of rated operation cycle efficiency, introduction of electromagnetic compatibility (EMC) test, revision of exhaust gas test, introduction of typical durations of operation cycles.

Describes guidelines for measuring the efficiency of power conditioners used in stand-alone and utility-interactive photovoltaic systems, where the output of the power conditioner is a stable a.c. voltage of constant frequency or a stable d.c. voltage.

IEC TS 60076-20:2017(E) is applicable to transformers in the scope of IEC 60076-1. It proposes two methods of defining an energy efficiency index and introduces three methods of evaluating the energy performance of a transformer. The appropriate method is chosen by agreement between purchasers and manufacturers or according to local regulations.
