Where and how to use portable ground

Typically, such systems find application in the areas of electrical installations that have no classical grounding blades.And the principle of action is that the portable grounding elements 10 kV or any other, is not allowed to pass the voltage value of which can be dangerous for a person on their places of installation.

In the case of supply voltage directly to the shorted section automatically short-circuit occurs.Consequently, the voltage at this point is lowered to zero and the voltage source which feeds the device is automatically disconnected.So portable earthing ZPL 10 or RFP 15, in fact, guarantees the safety of personnel dealing with the specific installation.

If you are going to buy the system under consideration, we must understand which device it has, and by what works.Its members will include:

  • special wires for grounding and shorting between conductive parts are separate installation phase;
  • clips, allows you to attach the wires to the live parts and ground wiring.

And Portable earthing STD or other means that are in it will be the use of wires made of a special, flexible stranded bare copper wire.But the number of phases in the system will depend directly on the value of the voltage supplied to the unit - they can be one or three.

Basic requirements for portable earthing

If we talk about the basic requirements to be met by a portable earthing ZPL 1 or RFP 1 as well as all the other existing options, you need to stop for a few moments.The main of these requirements are dynamic and thermal resistance to a short circuit current.

used when the organization of the system clips should be strong and to ensure reliable contact.And remember that the quality of these clips directly determines the price of all the earth - this is not the option, where you can save.

Serious demands are made to such indicators as the thermal resistance conductors.Regardless of whether one uses a portable system ground 10 square or any other, the conductors must be different resistance to high temperatures.Indeed, in the short-circuit point, they become very hot.And to see how these or other conductors satisfy the requirements imposed on them, the specialists carry out certain tests.

Portable grounding for SIP: what it is, and what specifics they have

To improve the reliability of functioning of overhead power lines today are widely used CIP system.However, it is important to ensure the safety of all electrical works in the service of this system.And because, for CIP requires special ground.

Portable grounding for SIP : what it is, and what specifics they have

They are chosen according to certain criteria and must meet a number of requirements.And just before you start using specialist must necessarily be carried out testing of portable ground chosen for the SIP security on overhead power lines.And it is important to note that in most cases the price of portable ground purchased by the customer in a particular company, already includes the cost of all the test work.

In conclusion

Summarizing, we can conclude that in the absence of the equipment or installation of a standard vanishing, there may find use grounding portable PZRU 1M or PZRU 1H.

In conclusion

However, besides PZRU 1M iPZRU 1H, there are other types of temporary ground.And some of them give preference in each case should be decided by an expert.It is only important to remember that before using portable ground RFP 1, or any other need to be tested on a specific procedure.Moreover, implementation of this type of work is also necessary to entrust a highly qualified professionals.
