Task 3: (P9)
a) Equipment such as switchgear can be worked on safely by ensuring a range of actions have taken place. The equipment used on the high voltage lines are the same.
a. Create a safety program
b. All of the sources of current to the equipment should be isolated and signs need to be fixed to ensure that the nature of the equipment is known
c. Ensure that the equipment is isolated by proving it
d. Ensure that all necessary earth connectors are then attached to the isolation points and any overhead wires
e. The permit of work is to be issued to allow the work to go ahead. It must include marking the point of work as well as showing the competent person the safety arrangements that are in place for the duration of the work
f. Complete work
g. Make the work safe and check that this is the case
h. Destroy the permit to work as well as cancelling it
i. Place equipment back in a state that will allow normal operation.

The first method of insuring a correct reading is obtained is through using one wattmeter on a balanced load. Using this on an unbalanced load will lead to an inaccurate reading for power. To complete this method a reading with a wattmeter connected from a single line to neutral via the voltage probes and in line with the line on the current probes. By multiplying the value of the wattmeter by three the total system power is found.
The second method of measuring three phase power is the useful for both balanced and unbalanced loads. By connecting a wattmeter with its current probes in series with red phase and volt probes between red and yellow phase. The second wattmeter should be connected with its current probes in series with the blue phase and the volt probes between the blue and yellow phases. By adding these two values together there total power for the system can be

Do you feel like having power is easy as turning on a light switch to to plugging an appliance into the wall maybe you do but after reading this your opinion might change.This research paper will discuss the idea of barehanding and how to work on energized power lines.
C. Two coils are placed end to end with an iron rod placed through them. One is connected to a galvanometer the other to a power supply. The power supply is switched on and off.

· B-phase transformer (EMTU-TT01) · Feedback electronic wattmeter · Multi-range moving-iron ammeter · Instrument voltage transformer THEORY AND INTRODUCTION ----------------------- Transformers are used all over the world to step-up and step-down electricity. The transformer is one of the most commonly used electrical devices. The reason the transformer is so popular is because they range in size from 240V to well over 240kV, stepping -up and stepping-down electricity all over the world.
To safeguard the EAF electrical system from the primary power supply are two types of switches: a vacuum switch and a motorized disconnect switch. These two switches are designed to isolate the EAF electrical system from the primary transformer in case of an emergency.
Maximum Demand is the power consumed over a predetermined period of time, which is usually between 8– 30 minutes. The most common period of time, in the majority of countries, is 15 minutes.
Analyse the need for selecting the different voltages used for different parts of the generation, transmission and distribution of electricity. Three Phase Systems Assignment 1 D1 Sean Smith JLR Electricity is the most used source of power in the modern world. We something that is connected too electricity practically all of the time in the modern era from mobile phones to the lighting in our homes. Thinking about where our electricity comes from is something that we never really think about but the cycle that electricity goes through before reaching us is quite a long process.

Wherever necessary, participate in the Lock, Tag, Test, and Try process for energized equipment. Verify lockout locations and make sure your personal control lock is installed at the correct spots. Most installations are performed outdoors in possibly wet conditions. When working in these areas with electrical tools, use ground fault circuit interrupters.
In power stations electricians need to use a variety of device to ensure that they are doing the job correctly. The four essential things an electrician needs to consider is earth wire, double insulation, fuse box and a residual circuit breaker. These four things are essential because they help to increase the health and safety of workers.
