RIGHILL FOWEB CONTROLS & DRIVE COT{VERTORSDEPENDABLE TECHNOLOGY, DIVERSITY OF APPLICATIONS

INTEGRATED SYSTEM DESIGNThe Integrated System-Design

approach has made it possible lorRighil l to produceDedicated type Electronic Controlsfor a variety ot applications.Employing Innovative electroniccircuit designs, combined within-depth understanding ofoperational and performance

PANEL CONFIGURATIONSBighi l l equipment is

characterised by one of the mostcompact yet spacious - for -maintenance designs available inthe world. Also, the compaclelectronics make it feasible forFlighil l to readily produce equipment in required sizes for f itt inginto applications where spaceis at a premium, e.g. mobilemachinery, locos, etc.

Standard Righil l Panels whichcontain all LT switch-gear,Electronics & Metering are 500- mmwide x 1800 mm high fes upto 1.2 MW415-V Power Controls,&400 Amo.750 V DC Drive Convertors. PowerControls for higher MW,z Voltage arein 2235mm high cubicles.Cubicles of800-mm width and 2235 mm heightare provided for convertors upto2000-4, 1500-VDC. and V-V ACControls upto 1600-4, 1100-V AC.Factory assembled l ine-ups aregiven for a complete system-package.

CONTROL ELECTRONICSAC MODULE INPOWER CONTBOLS

These modules contain all theelectronics for power control ol aDG/TG set used in Dril l ing Rigs.Industrial Stand-By/PrimePowerSets, Marine, Aviationgroundpower, Mobile sets etc.Main features:* High performance AVR with

exciter current l imit.* Highly stable, accurate & fast

response diesel engine fuel/speed electronic governor. OnlyAVR function is orovided ifneeded.

* Automatic KW and pre-setreactive KVA sharing betweenany number ot engine/gen. sets.

* Stablised power supply activatedright lrom start of engineobviating need of externalsupplies

requirements, Righil l havesynlhesized all the Control &Protection Electronics variationsinto single Electronic ControlModules covering a vast range ofapplications The ElectronicControls therelore do not have to beconceptualised afresh with amultiplicity of cards in each case,

which also eliminates anv chancesot system defficiencies.

Other advantages areeconomy, higher reliabil i ty ---- sincethere is much less electronichardware to cost or fail, coupled withsimplicity due to absence of a mazeof PCBs thus avoiding speciatiseddeciphering.

. Inlernal layouts are verticallyoriented ano seggregated type withfront and safe access to thecomponents. High quality compo-nents are used lo ensure tro-uble free service. Convertor Bridgeconstructions are in two halves.

"No-Failurgg"-Life-Time Warranty

An Electronic Control Moduleleaves Righi l l works only af ternear-zeto dri lt has been achieved inthe circuit characteristics/outputsafter conducting the burn-in tests onthe whole module ( instead ofjndividual cards) at 7O"C ambienttemperature. lor 192 hr at peakloading, thus weeding out anyinler ior i ty what-so-ever.

The electronlcs is made 10remain absolutely unaffected fromdust. morsture or harsh

environment. Righil l achieve thisfirstly-by employing circuit designswhich keep component loadingswithin l imits, secondly, by gradingand sizing the components andthirdly, by providing a hardcontormal protective coating overthe PCBs. Also, bumps, shocks andvibrations, exceeding far beyond thevalues generally specil ied indifferent applications, eg. marine,traction, etc. do not affect theelectronics since Righil l designaccommodates tast securedcomponents on a thick PCBmounted in a vertical plane. Thereare no plug-pin joints on the PBCS tocontaminate with grime or loosenby vibrations.

All above factors contribute to'eliminate any maintenance exceptfor occassional on-line routinechecks, for which there is a built- inmeter. A Righil l Module, wouldtherefore need replacement rarely, ifever, due to only an, 'e lectr icalaccident' and the replacement workitself would require a few minutes,thus minimjsing down t ime.

Righil l Electronic ControlModules, therefore, carryLife-Time-Warranty.
