CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
In this project, I had carried out preventive maintenance of low voltage switchgear
system at predetermined intervals. I had checked to reduce probability of failures into the
operation of systems. When there are occurrences of malfunctions of switchgear, then the
influences are catastrophic. When the switchgear is damaged, then it is expensive to overcome
with the failure. I had discussed two types of preventive maintenance such as: periodic and
conditional maintenance. For each of the product type, I had carried out the maintenance
recommendations by IS/IEC standards. The verification procedures intended to maintain of the
low voltage switchgear system in its operating conditions. I had performed conditional
maintenance to reduce recommended periodic and maintenance operations. It is required for
yearly power failure of the installation. The basic characteristics of this project work are
protection of the switchgear that is interruption of short circuit as well as overwork of the fault
currents that will uphold the service of unaltered circuits.

CE 3.2.2 Objectives developed for the project
Following are the objectives of this project work:
 To carry out of overhauls on electrical plant, machinery and equipment as part of
preventive maintenance
 To analyze machinery operations of low voltage switchgear system
 To undertaken of Quality Environment Health and Safety (QEHS) inspections on the
machineries
CE 3.2.3 My area of work
I had undertaken various machinery operations work such as preventive and break-down
maintenance of low voltage switchgear system. I had attended breakdown of electrical as well as
electronics on machinery, apparatus, plant, business utility services and structures necessary for
production purposes. I had supported maintenance and operation of machinery such as air
conditioning and ventilation systems, refrigeration systems, pneumatic systems, and power
generators. While working into my plant maintenance engineering area, I had applied safety acts
and policies to the workers so that all the personnel can work safely within the factory. I had
mainly worked for maintenance of the machinery operations of the plant equipments for proper
success of this project work.

CE 3.2.5 My responsibilities throughout the project
I had inspected electrical, instrumentation and control functions of the equipments. I had
also carried out overhauls on the electrical plant, machinery and equipment as part of preventive
maintenance. I had given training to the machine operators on new commissioned machinery and
assisted to set of machines based on product specifications. I had recorded, analyzed and
controlled of utilities usage and maintenance into the plant on daily based. I had maintained of
proper records of maintenance works and given reports on daily based. I had undertaken QEHS
inspections for preventive maintenance. I had monitored the performance of the plant machinery
and provided recommendations to the maintenance manager to improve including identifying

spare parts required. I had performed process area walk-about to identify problems, potential
problems & opportunities for improvement and maintenance including system changes.
CE 3.3 Distinctive Activity
CE 3.3.1 Comprehending the Theory of the project
Into an electrical power system, switchgear is combination of electrical disconnect
switches as well as circuit breakers which are used to control and protect of electrical
equipments. This kind of equipment is directly linking to reliability of electrical supply. I had
analyzed that a low voltage switchgear with consisting of rear access is being designed to use
into large electrical installations. The conditions of the plant are severe such as there is
involvement of higher currents and short circuit levels involve to high performance switchgears.
With preventive maintenance of the machinery operations, there is guarantee of safe conditions
of personnel, maintenance and installation. Maintenance practices of the machinery are carried
out through the plant industry and it is not appeared to be correlated with size of the firm.
Preventive maintenance is being supported by an enhancement of vital signs of monitoring. I had
determined that maintenance work of low voltage switchgear consists of periodic verifications of
the electrical installations. The electrical switchgear and equipments are continued to age
whether it can operate or not. In order to make sure that the system is retained safely, it is
required to install the device into optimum environment. Therefore, I had carried out regular
basis maintenance as well as inspections. I had analyzed that based on two components
switchgear operates: power conducting and control system. Therefore, I had mainly carried out
the preventive maintenance of these two components.

CE 3.3.2 Engineering Knowledge and Skills applied in the project
I had used my plant maintenance engineering skill to undertake of planned and
breakdown maintenance of the plant maintenance. I have team working skills to cooperative with
all people at all levels. I have knowledge of working into plant and maintenance of the
equipments to cope up with system failure issues. I am highly competent into process control as
well as system design of power supply. I have capability to use of mathematical model to
analyze the process controlling and power system. I have skills to model of different conditions
which occur during the plant operations.
CE 3.3.3 Accomplishment and task performed
I had analyzed some of the factors that accelerate the device ageing of low voltage
switchgear such as temperature, relative humidity, corrosive atmospheres and current harmonics.
Switchgears consist of isolation of the circuits from the power suppliers. The main function of
switchgear is used to determine of system availability by allowing of more sources to provide for
a load. I had inspected physical, electrical as well as mechanical conditions of the switchgear. I
had performed of acceptance testing to verify if the equipment data are matched with the project
drawings as well as specifications. Switchgears are designed and rated for particular
specifications. I had inspected of electrical, instrumentation and control functions of equipment. I
had kept documentation into safe place while loose parts as well as switchgear tools are stored
outside for easily access it.

CE 3.3.4 Identified issues and their solutions
CE 3.3.4.1 Issues
The electrical equipment’s as well as power distribution systems are not working
properly. Due to power failure, sometimes the system stops working.
CE 3.3.4.2 Solution
Proper backup should require to be place before there is breakage of power while
maintaining of the system.
CE 3.3.5 Plan to produce creative and innovative work
The electrical switchgear is rated as 1KV and therefore it is termed as low voltage
switchgear. It consists of low voltage circuit breakers, switchers, off the load electrical isolators
and earth leakage of the circuit breakers. All of those accessories are needed to protect of the low
voltage system. The common use of this low voltage switchgear is low voltage of distribution
board. The low voltage switchgear consists of incomer that is feeding incoming of the electrical
power to incomer buses. The low voltage switchgear that is used within incomer requires main
switching devices. The devices are attached with the incomer that has capability to withstand of
abnormal current for short detailed duration to authorize downstream devices in order to
function. The air circuit breakers are used as interrupting devices. I had analyzed some of
features of low circuit breaker circuits such as effective performance, simplicity and higher
normal current rated upon 600A. It has higher fault withstanding of capacity consists of 63 kA.
The air circuit breakers consist of long tripping time and higher cost.

conformances. I had conducted this work with help of maintenance engineer and my colleagues
to fulfill the obligations. I had worked pleasantly with the other team members and displayed a
good and natured cooperative attitude towards the project work. I had maintained of accurate
records of all maintenance works executed and provided reports on daily basis. My maintenance
manager had assigned with various duties from time to time. I had updated all the work on timely
manner.
