## New Wiring Rules and cable current ratings calculations

#### Clauses of AS/NZS 3000:2018 affecting cable current-carrying capacity

Discussion of the changes to AS/NZS 3000:2018 affecting cable current-carrying capacity.

## Maximum Demand Tables

#### Diversity factors for domestic and non-domestic installations

Reference tables for diversity factors and energy demand from Wiring Rules AS/NZ 3000 for domestic and non-domestic installations.

## Maximum Demand

#### Determining the total demand for an electrical installation

The 4 main approaches for determining the maximum demand of an electrical installation are discussed.

## Earthing modelling of concrete slabs

#### Utilise Steel Reinforcement in Earthing Designs

Switchgear in substations is installed on top of concrete slabs containing substantial quantities of steel reinforcement. Often the embedded steel reinforcement is bonded to the main earthing system and used to cost-effectively improve earthing electrical performance and safety.

## Teaching using Electrical Software

#### Educational institutions are using industry software to prepare students

Industry is using software to perform electrical calculations and Educational institutions have recognised this

## Transmission Line Tower Earthing Analysis using SafeGrid™

#### Design safe earthing systems for transmission towers

The purpose of transmission line grounding is to provide adequate lightning performance of the line; and effectively dissipate fault current avoiding the build-up of unsafe step and touch potentials around the tower base.

## Accurate voltage drop calculations

#### Provides the accurate equations

Accurately calculating voltage drop results in lower voltage drops which leads to smaller cable sizes and saves money.

## Extensive Study of Earthing Grids

#### Parametric study of earthing system performance.

An extensive study of earthing grids using SafeGrid software designed for determining performance of grids of arbitrary geometrical configuration in two layer soils has been undertaken. The study confirms work by Dawalibi and Mukhedkar undertaken using similar software called CDEGS®.
