Temporary Power Stations Utility Installation

Temporary Power Stations. In order for work at construction worksites to commence, its design has to be approved by the state departments. It also has to obtain certain permissions from certain related and concerned departments for work to start off at the worksite. But after the initial legwork, all work that needs to be done directly or indirectly needs to have an electrical inlet. Setting up permanent lines and obtaining connections from the concerned state electricity department is a hassle which most construction companies cannot take up at this point of time. Hence they resort to take help from rental agencies who are well-versed with laying down temporary power lines and grids.

 

The whole process of the same involves the following steps:

  • A dedicated crew visits the worksite and draws up a site map along with the grid design.
  • After this technicians who will actually be involved in the project go for a construction worksite inspection to judge the feasibility of the plan and also to decide on their next course of action.
  • On the basis of their report, the worksite design is tweaked and the final plan drawn. This plan is then presented to the relevant state authorities for obtaining the required temporary permissions and sanctions.
  • These very technicians then liaison with utility companies and other agencies located in and around the worksite so as to work in tandem with them.
  • Then the materials required is purchased and the delivery of the same is co-ordinated in a way that it takes place at the designated worksite.
  • These materials are then installed as per the final plans drawn and a temporary power grid is set up. All the necessary tools and equipments are provided for by the rental agencies and the construction company has to bear no hassle.

This makes it an attractive proposition for them as they save money and valuable manpower who can be gainfully employed elsewhere.  In fact the construction rental agencies also rent out generators and cable ramps as and when required.

Generators are considered to be a secondary source of power which can take over for a short time when and if the temporary power installation fails. The specifications of generator rentals include:

  • Electronic governor which enables crystal sync and are thus much more precise and have greater control over the frequency of the power,
  • A single point lift with a 110VAC receptacle which ensures its utility even in low voltages,
  • The sub-base is able to contain 100% of the liquid,
  • An alarm which indicates when the fuel is below dangerous levels and needs to be replenished,
  • Easy selection of voltage from the three parameters of 120 by 240, 120 by 208 or 277 by 480,
  • A wireless system called the site guard monitoring is also present and works ceaselessly to monitor the real-time occurrences of critical events taking place while the monitor is working,
  • A minimum level of sound emission which generally does not exceed 63DBA,
  • Capacity of the generators given on rent varies from anything between 5kW to about 1000kW and the installation of the same is done after calculating the load factor of the worksite.

Cable ramps that are available are meant for both indoors as well as outdoors and come along with a cable protector and a hinge situated at the top to facilitate ease of access. These ramps enable light vehicles to travel over the cables without damaging them and also reduces chances of tripping and falling of people and overturning of vehicles. These ramps are generally given out on rent along with the installed temporary power grids since thick cable tend to run across the ground at places where it is not possible to keep them in a hanging position. The cable ramps thus help as a cable concealer and also provides safe access across it.

One of the most important points top consider when opting for a temporary power station is that it is as hazardous as a permanent station. Hence the designing and installation should only be done by experienced and knowledgeable technicians and electrical workers. The installation also has to comply with the codes set by the government not only to ensure its legality but also because any code complaint installation is always considered to be a safe installation. This ensures that the worksite is safe for all people working there and also for anyone who comes for a visit to the worksite.

Some things which define the basics of the installation include:

  • Calculating the minimum and maximum power requirement at the worksite. This needs to be done taking the future implementation of heavy machinery into consideration and one should always keep a buffer for any sudden increase in the consumption of power during the period of the construction,
  • Diving the total power required into phases defined by the different cycles of the actual construction process and
  • The time period for which the temporary system needs to be operational. This depends on when the installation for the permanent electrical systems is completed and the permanent system is ready to take on the load from the temporary system.

Thus there has to be an absolute sync between the electrical contractors and the clients requiring temporary power so as to do away with any discrepancies which might crop up and make the whole construction cycle a hassle free experience.
