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
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
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
In this article, we discussed Problems Due To Unbalanced Load & whether Electricity Bill increases due to unbalanced load at house and tried to answer the question of the subscriber’s issue “വീട്ടിലെ ലോഡ് അൺബാലൻസ് ആയാൽ കറന്റ് ചാർജ് കൂടുമൊ? Here we have also discussed transformer balance and creation of neutral voltage due to unbalanced load and chance of services wire or main feeder wire burning due to overloading of one phase.

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
