Programmable Dynamic Load Manager (PDLM)

PDLM is used to maintain the constant actual power demand of the plant from the supply line. If actual KVA tends to exceed the sanctioned KVA, the PDLM reduces the power of the induction furnace. By using PDLM, maximum sanctioned KVA can be utilized, which optimizes the overall load factor of the plant. When more than one furnaces are in operation on a single grid, PDLM can work still more effectively by sharing the total available power. Power to the furnace can be shared through priority selection switches wherein one furnace can be provided full power while the other runs at reduced power. The overall productivity of the plant will increase because of the optimum use of available power. No human intervention is required for monitoring and controlling furnace load. CT & PT failure protection is provided in the system which reduces power to a minimum with an alarm indication.


We convey our sincere thanks and our appreciation to M/ s Electrotherm family for the development, realization, testing, qualification and commissioning of 10 MW power supply system for our Plasma Wind Tunnel facility. We are extremely glad that M/ s Electrotherm has taken up this challenging task, when no such system was existing in the country. We wish, we should have many more such collaborative ventures in future with M/ s Electrotherm and contribute to ISRO's futuristic advanced R&D programmes.
Mr. P.A. Krishnamoorthy, VSSC-ISRO
Hereby we feel glad to have 4000 KW/ 10 Ton DTi Furnace set along with HSMC lX Caster. We have commissioned this equipments in our plant on 21st May 2018 & found performance which was committed by Electrotherm was achieved. Electrotherm's project execution was extraordinary & their process understanding & support was remarkable. Looking to the performance of other equipments of other makes running within our group, we have found performance of Electrotherm make DTi Furnace to be best.
