How to find the underground electric cable?

1. Before start excavation use cable deductor for under ground cables.
2. We can take help from area drawing for cables also.

I go back to the designed diagram,and there is always a warning tape burrired with cables

1-in my experience to find the cables under ground, there are metal detectors, or detectors of electric fields, that electricity generate a magnetic field, the sensor you can place the designated cables.

2- where excavation techniques, how ??, the burial depth of the cable is a meter to avoid the excavation depth should be small plate depth

The electrical cable emits a signal which can be tracked on the surface with a Cable Locator instrument before you dig. Hand excavation should be used to then find the exact location before machine excavation is then used to carry out the project.

The basic principle on which, the underground power line locators work is very simple. A cable that has AC power passing through it generates signals of its own in the frequency level of 50 to 60 hertz, jointly with greater frequency signals; this concept provides a foundation for finding the buried lines with the help of a passive receiver.

pole slipping becomes a real possibility in the event of a system fault. The 'slip' occurs when the rotor experiences a sudden physical and electrical shift in position relative to the stator, after which the field recovers enough strength to lock the rotor back in synch with the stator. When his occurs, the violent acceleration and deceleration associated with pole slip causes enormous stress on the generator and prime mover, and may result in anything from winding movement to shaft fracture or worse.

To find the cables under ground,you can use metal detectors, or detectors of electric fields, that electricity generate a magnetic field, the sensor you can place the designated cables.

By using the cable detectors and making the trial trenches

Under Ground Electric Cable can be found using sound probing test to identify and Isolate the before excavation take place

1. Before doing any excavation get the clearance form the concerned authorities like electricity boards, water authorities and other utility services to ensure the area is safe to excavate.

2. Also consult with the pre-occupier of that area to ensure the same

3. use of calibrated and quality detectors to find the cables

4. Incase the equipment is not available , trial holes dug using suitable hand tools as necessary to confirm this

 I need to figure out where the line going to the house ends. If I put the extension cord on it.
