Day one
Fundamentals
- Volts, Amps and Resistance
- AC Electricity, Capacitance and Inductance
- Real Power and Reactive Power
- 3-Phase Electricity
- Power Transformation
Earthing
- Basic principles of earthing
- CNE/ SNE – why
LV Network Components
- Functions types and sizes, why they look they do:
- 3 phase cables
- Service cables
- Mechanical protection
- Joints and link boxes
- Cut-outs and fuses
- Transformers
- RMUs for HV connection
- OH lines
Economic Design Rules
- Diversity – the importance of sharing – After Diversity Maximum (and Minimum) Demands
- Sizing and Thermal Ratings Exercise
Day two
Network Constraints
- Network Planning Regulations
- Thermal and Voltage constraints
- Fault level – too much or not enough – earth loop Impedance – fuse reach
- Power quality considerations
Representing Customers in Modelling Tools
- Profiles
- ACE49
The Age of Electric
- New loads appearing on LV networks – solar generators, plug-in electric vehicles, heat pumps
- Strategies for design to accommodate them
- Final exercise
Open Discussion
Day three
The optional third day will introduce you to the LV network design tool VISEA® Connect. Benefiting from the knowledge gained in the first two days, you will undertake several practical exercises using VISEA® Connect to design networks with different properties including PV generation and EV chargers.
Fundamentals of VISEA® Connect
- Background to the software package
- Core standards and a brief overview of the software methodology
- Key modelling components
Step-by-step Walkthrough of the Modelling Package
- A complete step-by-step walkthrough of the software to:
- Assemble a network
- Study embedded generation
- Assess and interpret results
Practical Sessions
- Network design exercises of varying difficulty to put into practice lessons learnt
