| 1 | Supply, installing, testing and commissioning of PDB Panel 800A, 415V. The panel shall be indoor wall mounted. It shall be completely made of CRCA sheet steel. | The enclosure shall have sturdy support structure with angle suppors as necessary. Enclosure shall be finished with powder coating, after finishing 10 tanks chemical treatment. Paint shed shall be RAL-7035.Suitable provisions shall be made in the panel for proper heat dissipation. Air aspiration louvers for proper air circulation shall be provided as necessary.The panel shall be suitably sized to accommodate all the compor ents, providing necessary air clearance between live and non-live parts, providing necessary working clearance. Incomer shall pe Al busbars. Power Outgoing shall be one 800A, 415V, 50kA, TP, MCCB, TM. Bus bar shall be of Aluminium with 0.8A by sq. mm current dens ty. Suitable Indication lamps for - Phase supply indication and Circuit Elreaker - trip indication should be provided. MCCBs shall be with door inter ocking protection systems. Bus Bars shall have coloured PVC sleeves. 800A outgoing shall be used to feed the 430kVAr, 415V Step-Less PF Correction System complete all as specified anc directed |
| 2 | Supply, installing, testing and commissioning of PF Correction Panel with RMS 430kvar, 415V. panel indoor floor mounted, free standing with IP-31 degree of IP made of CRCA sheet steel. | The enclosure shall have sturdy support structure with angle supports as necessary. Enclosure shall be finished with powder coating, after finishing 10 tanks chemical treatment. Paint shed shall be RAL-7035. Suitable provisions shall be made in the panel for proper heat dissipation. Air aspiration louvers for proper air circulation shall be provided as necessary. The Step-Leiss PF Correctior Panel system shall be without any PF Correction passive capacitor banks, but single or mutiple module combination of Static VAr Generator, which can measure the actual requirement of reactive currents and produce and inject the same reactive currents Inductive or Capacit ve as per the system needs to compensate the Reactive Power Demand individual phase -wise. There shall be one Hill cum SVG Controller digital signal processor to sense the load current and operate the SVG Modules connected with the SVG Panel. Reaction time of that DSP shall be 10 mSec, so that cycle to cycle compensation to be established. The HMI display unit shall have 15channel Oscilloscope to display live-status of the 3Phase voltage, Load current, Grid Current and SVG currents, along with all major electrical PQ parameters. SVG modules should have efficiency of less than 98 percent and internal losses 2 percent of its full capacity. The SVG modules shall have internal fan for heat dissipation by force air cooling method. Maximum 50 no.s modules can be connected in parallel per CT set. The SVG modules should be operated within the voltage range 350V to 480V. ambient temperature should be 0-45 temp C. Noise level shall be 5db. Built-in semiconductor-fuse protection for the SVG modules is a must. Load CT shall have 5A secoridary and in general it will be connected in close loop. Full rating of individual STATIC VAR GENERATOR moclule shall be 125kVAr, 480V, 1504, which will output 107.8kVAr at 415V AC. So, considering the 4nos of modules it will output 431.2kVAr at 415V. |
