How to Connect Earth to SPD for Homes Earthing Guide for Surge Protection Device No Separate Earth For SPD shishiram engineering services
In this article, we discuss briefly How to Connect Earth to SPD and where to place SPD at your home. this complete article is based on Earthing Guide for Surge Protection Devices by Eaton. The limiting voltage can be lowered by re-positioning the earth connection. Locating the equipment earth (i.e. its zero-volt reference) at the SPD earth point produces the configuration shown in figure 19. Placing Type 1 & 2 SPD in energy meter box where power cable enters the house and at the same place is the nearest point to earth pit. The equipment is now subjected to an Read more
How to Do Proper Earthing at Home
In this article, we discussed How to Do Proper Earthing at Home. We have to install a minimum of 2 GI earth pipes of 2.5 to 3 meters long with a minimum of 38 mm diameter at a distance of 5 meters between the pipe and 1.5m from the building. If we want to connect the earth link to the DB. The right way is to take two separate copper SWG wires from each earth pit to the energy meter panel and from the energy meter panel to DB use 2 same sizes of wire as phase wire and if Read more
After Installing Solar Power Plant On-Grid or Off-Grid, Is It Profitable or Not in a Year Shishiram
In this article, we discussed After Installing Solar Power Plant On-Grid or Off-Grid, Is Profitable or Not in a Year? and we have tried to ask questions about our subscriber’s comments. First of all, something getting profitable or touching breaks even depends on how much amount of money one was paying before installing a solar power plant and how much money he or she paid for installing this power plant. Basically, government subsidies for domestic users especially small users make it non-profitable in the short run. But for bigger domestic consumers it is still very profitable. The solar power plant Read more
Do We Need Two Separate DB for Inverter & Main Supply RCCB Tripping in 2 DB Earthing Connection
In this article, we discussed whether we need separate DB for inverter supply and main supply or KSEB supply. Is this required by Kerala Supply code rules. Are we preferring to using 2 separate DB. How to connect earth link to these separate DB. General procedures that is required to connect earth pit and DB. Why RCCB in separate DB or 2 RCCB in single DB trips and what are the main solution for these problems. First, as per Kerala Supply Code it is not mandatory to have 2 separate DBs for inverter supply and main supply. But some countries Read more

Electrical Design Class-3 Electrical Resistance Conductance Ohm Basic Electrical Malayalam-min
The electrical resistance of an object is a measure of its opposition to the flow of electric current. The reciprocal quantity is electrical conductance and is the ease with which an electric current passes. The SI unit of electrical resistance is the ohm (Ω), while electrical conductance is measured in siemens (S) (formerly called “mho”s and then represented by ℧). Read more

Underground Cable വലിക്കുമ്പോൾ ശ്രദ്ധിക്കേണ്ട കാര്യങ്ങൾ Problems During UG Cable Installation
In this article, we discussed the important things to note during installation of underground cables and tried to answer the question of the subscriber’s issue “underground iloode cables vakkumbo enthokke sraddikkanam?” Here We have explained to check cable well before installation for any damage in outer sleave or layer since may eventually lead to cable damage if we install the cable with damaged outer layer underground in soil. We have also mentioned to use cable marker during installation and also install LT cable 75cm before ground level. All cable should be installed in straight line along the compound wall so Read more
