Logistics and network
Supplying Madhya Pradesh.
Deliveries across Madhya Pradesh start at about 440 km by road, which puts the nearer cities (Gwalior, Sagar, Ujjain) within 3 days of dispatch. The state's demand centres on Indore and Pithampur auto and pharma, Bhopal and Mandideep engineering, Jabalpur defence, Rewa and Omkareshwar solar, Singrauli power, Satna cement.
Distribution in Madhya Pradesh is handled by MPPKVVCL East, Central and West; MPPTCL runs the transmission network. Programmes now in execution include RDSS, Rewa ultra mega solar, Omkareshwar floating solar, and each is tendered against a technical specification that we quote and manufacture to.
The product
A solar transformer is not a distribution transformer with a different label.
An inverter feeds the transformer a non-sinusoidal current with significant harmonic content, and it does so on a duty cycle that is de-energised for roughly half the year. Both facts change the design.
Harmonic currents drive eddy-current heating in the windings that a standard design does not allow for, so conductors are transposed and the core flux density is de-rated to leave headroom. The overnight de-energised period means no-load loss dominates lifetime energy cost far more than it does on a distribution feeder — which is why the low-no-load-loss design is worth paying for here and not always elsewhere.
