COFRE DE PEROTE (TELCEL)

Project Date: October 3rd, 2005

1. Ohmic resistance:

Ground Resistivity Ground Resistivity Resistance of physical ground previously installed Resistance of Terragauss physical ground currently installed
Shelter
41.40 kOhms-m 505 Ohms 0.18 Ohms
Tower 1
11.07 kOhms-m 250 Ohms 0.16 Ohms
Tower 2
173.50 kOhms-m 2,130 Ohms 1.91 Ohms


2.- Voltage difference between neutral and ground inside the Shelter:

- Main board: 0.0 Volts.
- Contact: 0.0 Volts.

3.-Continuity measurement:

- Distance 1 m – it gets continuity
- Distance 30 m - it gets continuity.
- Distance 50 m - it gets continuity.

SITE CHOPCCA - CLARO PERU (AMERICA MOVIL)

Elaboration Project date: February 3rd, 2009

Ground type: Rocky.

Measurements of resistivity of the ground were taken in July, 2008 (dry season and low rain in the zone).

Resistivity measurements of the ground obtained are:
