PURPOSE OF THE UNIT STANDARD 
This unit standard is for persons in the Electrical Engineering; Generation; Distribution; Transmission; Construction and Renewable Energy Sectors.

A person credited with this unit standard will be capable of:
  • Assessing wind, solar data and the load to determine the need for a standby generator.
  • Determine the rating of a standby generator.
  • Understand and make provision for the logistics in respect of a standby generator.

    This unit standard will contribute to the full development of the learner within the electrical engineering and construction environment by providing recognition, further mobility and transportability within the field of Physical Planning and Construction. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the electrical engineering and construction environment.

    ASSESSMENT CRITERION RANGE 
    Clinics and hospitals, medicine and vaccine storage, food storage, security systems and lighting, emergency radios.
     

    ASSESSMENT CRITERION 4 
    The battery charge current is assessed as a critical load in terms of battery characteristics and limitations. 
    ASSESSMENT CRITERION RANGE 
    Battery characteristics and limitations refer to but are not limited to charge and discharge rates, depth of discharge and temperature.
     

    SPECIFIC OUTCOME 3 
    Determine the rating of a standby generator. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    The maximum rating is determined in terms of the value and duration of the critical peak load and the battery rating. 

    ASSESSMENT CRITERION 2 
    The standby generator usage is estimated in terms of the potential duty cycle, the battery storage capacity and the system autonomy. 

    ASSESSMENT CRITERION 3 
    A safety margin is determined in terms of the potential duty cycle, the battery storage capacity, the system autonomy and the wind and solar resource. 

    ASSESSMENT CRITERION 4 
    An economic assessment is made in terms of fuel consumption, generator rating, system size, battery ampere-hour rating and system autonomy. 

    SPECIFIC OUTCOME 4 
    Understand and make provision for the logistics in respect of a standby generator. 
    OUTCOME RANGE 
    Logistics includes but is not limited to:
  • Provision fuel and spares and carrying out of basic maintenance procedures. 
    		•

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    The standby generator is selected in terms of the logistics with regard to diesel, gas or petrol. 

    ASSESSMENT CRITERION 2 
    The standby generator is selected in terms of the type, service, manufacturer and availability of spares. 

    ASSESSMENT CRITERION 3
