1.3. Battery ChargerThe DC system for 220 V DC is unearth. The Battery Charger as well as automaticSl. No. Test Factory Site TestsTests1. Physical Verification √ √2. C/10 Capacity test on the cell √3. 8 Hrs. Charge and 15 minutes√discharge test at full rated loadregulators shall be of static type and shall be compatible with offered VRLAbattery. Battery charger shall be capable of continuous operation at the respectiverated load in float charging mode, i.e. Float charging the associated DC Lead-AcidBatteries at 2.15 to 2.25 Volts per cell while supplying the DC load. The chargershall also be capable of Boost charging the associated DC Battery at 2.3 +/- 0.02volts per cell at the desired rate. Charger shall regulate the float/boost voltage incase of prescribed temperature rise of battery as per manufacturers recommendationto avoid thermal runaway. Necessary temperature sensors shall be provided in midlocation of battery banks and shall be wired up to the respective charger forfeedback control. The manufacturer shall demonstrate this feature during testing ofeach charger. Battery charger should be thyristor controlled.1.3.1. Battery Charger shall be provided with facility for both automatic and manualcontrol of output voltage and current. A selector switch shall be provided forselecting the mode of output voltage/current control, whether automatic or manual.When on automatic control mode during Float charging, the Charger output voltageshall remain within ±1% of the set value, for AC input voltage variation of ±10%,frequency variation of ±5%, a combined voltage and frequency variation of ±10%,and a DC load variation from zero to full load.1.3.2. Battery charger shall have constant voltage characteristics throughout the range(from zero to full load) at the floating value of the voltage so as to keep the batteryfully charged but without harmful overcharge.1.3.3. Charger shall have load limiters having drooping characteristic, which shall cause,when the voltage control is in automatic mode, a gradual lowering of the outputvoltage when the DC load current exceeds the Load limiter setting of the Charger.The Load-limiter characteristics shall be such that any sustained overload or short_____________________________________________________________________T.No. DTL/DGM(T)SSC-II/GPL/09-10/GIS/GT-02Page 378 of 566
circuit in DC System shall not damage the Charger, nor shall it cause blowing ofany of the Charger fuses. The Charger shall not trip on overload or external shortcircuit.1.3.4.Uniform and step less adjustments of voltage setting (in both manual and automaticmodes) shall be provided on the front of the Charger panel covering the entire floatcharging output range specified. Step less adjustments of the Load-limiter settingshall also be possible from 80% to 100% of the rated output current for Chargingmode.1.3.5. During Boost Charging, the Battery Charger shall operate on constant current mode(when automatic regulator is in service). It shall be possible to adjust the Boostcharging current continuously over a range of 50 to 100% of the rated outputcurrent for Boost charging mode.1.3.6. The Charger output voltage shall automatically go on rising, when it is operatingon Boost mode, as the Battery charges up. For limiting the output voltage of theCharger, a potentiometer shall be provided on the front of the panel, whereby itshall be possible to set the upper limit of this voltage any where in the output rangespecified for Boost Charging mode.1.3.7.The Charger manufacturer may offer an arrangement in which the voltage settingdevice for Float charging mode is also used as output voltage limit setting devicefor Boost charging mode and the Load-limiter of Float charging mode is used ascurrent setting device in boost charging mode.1.3.8. Suitable filter circuits shall be provided in all the charger to limit the ripple content(Peak to Peak) in the output voltage to 1%, irrespective of the DC load level, whenthey are not connected to a Battery.1.3.9. MCCBBattery Charger shall have 2 Nos. MCCBs on the input side to receive cables fromtwo sources. Mechanical interlock should be provided such that only one shall beclosed at a time. It shall be of P2 duty and suitable for continuous duty. MCCB’sshould have auxiliary contacts for annunciation._____________________________________________________________________T.No. DTL/DGM(T)SSC-II/GPL/09-10/GIS/GT-02Page 379 of 566
