Dismantling of old unserviceable Power Back Up System & Supply, Testing, Commissioning Ripple Free Power Supply Unit with First Stage conversion : Power Factor Correction along with H.F. filter and input AC Voltage Rectification and conversion in high voltage DC. ii) Second Stage Conversion: Rectified high voltage DC is stored in capacitors. High voltage DC is then converted in to a very high frequency AC (20 KHz and higher). Conversion of high voltage DC to high frequency AC is achieved by means of very powerful and ultra-fast semi-conductor switching devices. High frequency AC is stepped down to the required level by means of a small high frequency transformer with following specifications OUTPUT POWER FACTOR –O.8 LAG. OUTPUT FREQUENCY – 50 HZ+/-0.5% . WAVE FORM – 20 MILLI SEC PURE SINE WAVE . RESPONSE TRANSIENT - <8% ON 90% LOAD CREST FACTOR – 3:1 .

Dismantling of old Battery Bank and Supply and Fixing of in Replacement of Battery Backup 360 Volts 26 AH system with relays AC & DC operatable with extra relaying schemes attached to the equipment including part of the network with their own relaying system. Equipped with Backup relay’s to operate in any failure of Tripping of Circuit Breaker due to main relays capable to sustain Mechanical defect of moving parts of the main relay, Failure of DC Power Supply to the relay, Failure of Tripping pulse to the contactor / MCCB from Relay, Failure of Current or Voltage to the Relay from CT or PT circuits etc. Equipeed with another line of protection as back up relaying. essentially have everything separate from main relaying scheme. just because backup relay must not fail to operate in the event of failure of main relays. in spite disconnect main relays from the system for preventive maintenance or trouble shootings. Because of presence of backup relays, no interruption has to take place for 11 KV equipment or circuit. During this time back up protection scheme takes care of the protection of the system. As the back relaying is second line of protection it must be slow in action than main relay so that it can only be operated when the main relaying scheme of the system/equipment fails.
