Radial and Ring Main Distribution System Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12968
Indian Lab Suppliers supplies the Radial and Ring Main Distribution System (Product ID: 12968) as part of its electronics engineering lab equipment range. It compares voltage regulation in radial and ring main distributors on a low-voltage DC model.
Quick Answer
The panel has separate radial and ring main sections loaded by lamp holders and fed from an isolated, variable 0–220 V DC supply (2 A) derived through a 0.5 kVA, 230/150 V transformer and a 0–270 V variac. Three digital DC voltmeters and three digital DC ammeters read voltages and currents in the distributor sections, so students can measure the voltage drop along each system. A radial feeder fed from one end shows the largest drop at the far end, while a ring main fed from both directions keeps the voltage more even and can still supply a load if one section is opened.

Where This Is Used
Used in power systems laboratories for distribution system and voltage-regulation experiments. The DC output reaches 220 V and the lamps get hot, so connect with the supply off.

Frequently Asked Questions
Is the supply AC or DC?
The distributors run on an isolated variable DC supply of 0–220 V.
Why is a ring main better regulated?
Each load is fed from two directions, so the current and voltage drop per section are lower.
How many meters are fitted?
Three digital DC voltmeters and three digital DC ammeters.
