Objectives of Safety

Objectives of Safety During Operation and Maintenance of Electrical Machine.


Testing and maintenance of electrical machines is an important and critical job intended for safety of operating personnel surroundings, machines etc.


Procedures for testing and maintenance of electrical equipment are well defined and abide by the I.E. rules. These rules are to be strictly followed.

Objectives of safety during maintenance of Electrical Machine
Objectives of safety during operation and maintenance of Electrical Machine

Safety must be given top priority in the working process right from foundation,
commissioning, testing, working and maintenance of the equipment.

Objectives of Safety

From this brief discussion we can write the objectives as follows:

  • To take care of equipment and persons concerned.
  • To take care of the premises in which equipment is located.
  • To take precautionary majors in transportation of equipment.
  • To take precautions in loading and unloading of equipments.
  • To take primary inspections, that wirings, fittings and accessories are not damaged.
  • To take precautions for proper assembling of parts.
  • There are I.E. acts/rules for safety at work.
  • Printed cards are to be made available, and displaced at proper places.
  • Warning signs are to be displayed.
  • Permit to work  'permit cards'  are be issued.
  • To give work-book keeping awareness.
  • To give responsibility of work to responsible person, supervisors.
  • To take immediate actions in emergency cases.
  • To give training - 'How to avoid accidents'.
  • Put Do's and Don'ts lists.
  • To give training for causes of electric shock, how to avoid and take care.
  • To give training to cure persons from electric shock.
  • To train a group of persons for artificial respiration method.
  • To make aware from causes of electric fire how to attack fire.
  • To keep equipment periodically tested "as fire extinguishers"
  • Issue draft of permit to work and to shut down
  • To keep a card explaining "Know your machine".
  • To keep time table well displaced giving program of maintenance schedule, hourly, 
  • daily, monthly, quarterly, half yearly, yearly.
  • To check earthing system properly maintained.

  • To check oil levels kept for safety and cooling of machine.
  • Don't keep machine idle for a long period.
  • If kept and to be now commissioned check its mechanical and electrical conditions and
  • make necessary repairs, test, lubrications and then keep it ready for re-commissioning.
  • Keep the earthing system in well condition.
  • Check earth resistance.
  • Check protective systems whether in proper condition to act in abnormal happenings.
  • Warning bells, sirons to be kept ready in good conditions.
  • Appoint trained and qualified persons for the jobs.
  • Extend periodic training for new technology to be adopted.
  • To keep linkages, contacts, by various methods available.
  • Security department be aware and active and prompt in actions.
  • Cleaners and creeping.
  • Between two machine, appropriate clearance be kept for moments.
  • Between conductors as per the voltage rating specified.
  • Creepages, ground clearance of conductors as per line voltages be assured.
  • If adjustments and repairs are to be taken, then follow proper procedures laid down by the department heads.
  • Patrolling work be carried out at least once in a week to check the lines.
  • For maintenance, a shutdown is taken. Give prior notice for the same to the consumers.

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction To Arduino Arduino is an Italian company that designs and manufactures Open Source Hardware (Microcontroller) and Open Source software or IDE (Integrated Development Environment). Arduino hardware is such a programmable computerized platform, by working on which the user can combine the hardware and software and prepare the electronic brain according to his own and can control the electronic devices from that electronic brain. What is arduino? If you want to understand more easily, then we can say that Arduino microcontroller is an empty brain, in which you can upload memory by coding or programming through arduino software, so these are called open source. Arduino works like a CPU of a board computer. Right now the microcontroller of the arduino of this time that we can take up is lik...

Variable Inductance Transducer | Classification Of Variable Inductance Transducer

Variable Inductance Transducer | Classification Of Variable Inductance Transducer Variable Inductance Transducer | Classification Of Variable Inductance Transducer These are based on a change in the magnetic characteristic of an electrical circuit in response to a measurand which may be displacement, velocity, acceleration etc. Variable inductive transducer may be classified as follows: 1.Self-generating type In this type voltage is generated because of the relative motion between a conductor and a magnetic field. These may be further classified as follows: (A)Electromagnetic type (B)Electrodynamic type (C)Eddy current type 2.Passive type In this type the motion of an object results in change in the inductance of the coils of the transducer. These may be further classified as follows: (A)Variable reluctance (B)Mutual inductance (C)Differential transfer type 1.Self-generating Type (A)Eleotromagnetic t...
