Introduction
This unit is for those who are responsible for generator operation. It involves preparing a generator for location filming, installing the generator power distribution cabling, starting the generator, monitoring the controls and visual outputs, and balancing the generator loading. It is about identifying the incoming electrical supply system and analysing the electrical distribution layout. It involves connecting to the supply in compliance with BS7671, and undertaking visual risk assessments of site conditions. It also requires the ability to carry out fault finding.
This is aimed at those who operate generators. This is a level 3 unit
Unit 313
Install, operate and fault find on generators
Performance Criteria You must be able to:
1 carry out pre-checks as appropriate, including the sufficiency of running or replacement items appropriate to the location and production schedule
2 undertake a visual risk assessment of the site conditions and take appropriate action to reduce the risk of any hazards identified
3 position the generator safely in accordance with local bylaws and level the generator when it is necessary to do so
4 identify any special cabling requirements necessary for local conditions
5 establish the distribution requirements from the person responsible for the lighting 6 where provision for expansion for any third party is required seek permission to do so 7 carry out pre-energisation tests on the cable distribution system, with regard to polarity and
earthing, in accordance with the latest edition of BS7671 and BS7909
8 start the generator and ensure the controls and systems function according to manufacturer’s instructions, prior to electrical energisation
9 establish and adjust the supply frequency and voltage for the intended production 10 monitor the generator throughout its use in terms of its
y phase, balancing and loading y functioning
y fuel and fluid levels
11 accurately record generator running times, service requirements and vehicle mileage for records
12 monitor the operation of the generator at all times in an attempt to prevent faults occurring 13 where faults occur, conduct an assessment of safe working practices and carry out checks
on the generator to identify the fault and the action required.
14 identify whether the nature of the fault is electrical, mechanical, electronic or external to the generator and whether you can rectify it safely
15 where faults occur, obtain clear and detailed information about the faults relating to the systems and equipment and inform the relevant person, such as the Gaffer, as promptly as possible
16 carry out tests and checks of main systems, voltage and insulation resistance testing in accordance with health and safety regulations
17 follow the correct procedures when rectifying first line faults, including using the appropriate tools, equipment and materials
18 carry out generator, routine servicing and maintenance using the correct parts, tools and methods of fitting
19 when usage of the generator is complete, carry out payload and other vehicle management checks
Knowledge Criteria
You must know and understand:
a the importance of pre-and post operation vehicle management checks and of ensuring there is sufficient items such as lubricants, batteries, fan or drive belts and access to fuel/fluid for continued use during location shoots
b Health and Safety legislation and how to reduce potential health and safety risks to yourself and others.
c how to identify any safety issues and local hazards at the site which may affect generator placement and cable routing
d how to make calculations of load current with various types of load, both reactive and resistive and knowing the maximum loading of sub circuits and distribution boxes
e how to assess the generator’s earthing requirements when the generator is the sole source of power and when it is used in conjunction with other sources
f when to make provision for any additional earth bonding and whether any special permissions are required
g how to operate the generator, including in a level position to ensure exhaust emission poses no environmental nuisance
h how to identify the incoming electrical supply, and where necessary to provide a changeover unit and their implications to the shoot
i the principles of operating multiple generators and the benefits and the problems associated with them,
j the implications to lighting equipment and users, when a situation of load shedding or similar occurs, and the affect on generators and equipment in overload situations k how to test for electrical & mechanical problems with generator systems
l the requirements of the Electrical Safety, Quality and Continuity Regulations
m how to identify potential problems with the generator governing systems and automatic voltage regulators, the relationship between engine speed and frequency and how to solve problems in the systems
n how to meet Health and Safety requirements relevant to electrical tests and checks
o the appropriate legislation affecting the environmental use and storage of contaminants and pollutants & the correct disposal of such items.
p the current law and insurance liabilities with respect to violations of Road Traffic regulations whilst working and driving
Evidence Requirements
1 The majority of your evidence for this unit should be from observation of your performance in the workplace.
2 You may also use work products and records, witness testimony and records of professional discussions to demonstrate you can meet the requirements of the unit. 3 Simulation is not permitted for this unit.
4 Your assessor will plan your assessment with you to cover the whole of this unit and to show that you can consistently meet all of the performance statements. Your evidence may also contribute to all of the other units.
5 Your performance evidence should usually also cover the statements of knowledge and understanding. If it does not, your assessor may ask you questions, you may use witness testimonies or records of professional discussions to prove that you have a thorough knowledge and understanding.
