An acceptable resistance for a ground to ground plate system is 2 ohms with a maximum allowance to 5 ohms. If the measured resistance is above 5 ohms more grounding rods or plates have to be added to reduce the resistance down to the acceptable levels.

What is the acceptable pi value in insulation resistance?
The PI value depends on the type of equipment being tested and the voltage level. Roughly it shall not be below the value of 2.0
What is LV cable insulation resistance acceptance value?
The minimum acceptable insulation resistance value is calculated using the following formula: Rinsulation= (Vrated + 1 ) x (304.8 / L ) Where: Rinsulation is the minimum acceptable insulation resistance value, in mega-ohms; Vrated is the rated voltage of the cable (typically printed on the cable), in kilovolts; and L is the length of the cable, in meters (if the cable length is in feet, replace the number 304.8 with 1000).

The Advantages Of Grounding Module-Sichuan?
The advantages of grounding module Grounding module this product is also commonly known as grounding or grounding network, mainly to help improve the internal conductivity of the grounding conductor to reduce resistivity, the grounding module has good ability and good conductivity, low damage rate and other advantages, is also the "God of protection" of each electricity, the following on the use of grounding module advantages through the following a up to understand the following. Sichuan Sunlight Intelligent Long service life Grounding module using copper clad steel process material made of force is particularly good, long-term buried in the ground will not be a variety of moisture and other elements of corrosion, grounding module metal skeleton used is also processed metal materials, so improve the entire capacity of the service life of up to decades or more. Grounding buried deep Grounding module can be used in a variety of different and underground, and can be buried according to different occasions, in order to meet the low resistance value requirements to a variety of occasions, because the grounding module connection drive way, so can carry out a variety of different connections and use. Strong resistance reduction function Grounding module can be combined with the soil as a whole and can increase the contact area of the grounding body and soil, reduce the contact resistance to improve the efficiency of the grounding module, and grounding module in the use of the process can keep the surrounding soil wetness, grounding module can play a conductive function, reduce the contact resistance resistance resistance value. Wide range of use Grounding module can be used in different soil environment, including different temperature, temperature and PH value or resistivity change conditions of the soil environment, but also suitable for use in a variety of different power, construction, petrochemical, communications and other important industries, so grounding module can be called "omnipotent" grounding conductive materials. Grounding module is resistance reduction supplies. In the grounding ground network resistance can not meet the requirements. With the module and resistance reducing agent to reduce resistance, so that the resistivity of the ground network can be reduced to the ideal value. When the cores of the grounding module are connected in parallel with each other or with the ground, welding is performed. It is required to use the same metal material welding, the sex of the connection. The welding length should be no less than 80mm, and no false welding or leakage. Grounding module processing is very important, first of all, the correct installation of lightning protection grounding module is an important part of the ground network construction, lightning protection grounding module its design at the beginning, has taken into account the ability of the product itself, and the technology into the grounding module products, however, in the lightning protection grounding module installation process, incorrect installation will inevitably produce harm to the product's own materials, thus failing to achieve the use of the effect. In recent years, the gradual adoption of non-metallic grounding module. We are professional grounding module supplier, if you are interested in this, please contact Sichuan Sunlight Intelligent Co.
