FEATURES :The design of wire and plate grid, lends itself to various advantages over conventional cast iron grids and standard wire wound resistor assemblies. In the assembly design breakable parts are excluded, resulting in robust construction. In the wire grid assemblies, the unique terminal arrangement, facilities easy replacement of individuals grid.The assembly can tailor designed and is available in stack and panel mounting versions. This is ideal for compact design of special purpose control panels. The panel mounting versions has an added advantages of saving in interconnection and wiring.Material : Standard-stainless steel, other alloys request.Applications : Load Banks, Rotor Starters, Crane Controllers, Motor starting and braking resistors.

Discharge Test : Periodical discharge test on station batteries is a mandatory requirement for users. These tests ensure reliability, better service and enhance life performance of the battery system. Battery manufacturers specify Yearly / Half Yearly / Quarterly Charge / Discharge cycle tests.Advantages - Discharge cycle tests help the users to :1. Check initial battery performance against manufacturers specifications.2. Avoid deterioration of battery system due to early detection of defective cells.3. Guarantee smooth operation of back up system during emergencies.4. Improve overall health and life of battery system.Discharge Resistor : Our unit is designed to perform periodic discharge tests on station batteries. The resistor unit is a robust assembly consisting of Copper-Nickel Alloy wire grid elements, supported on S.S. tie rods, insulated from each other and the enclosure with Micanite tubes, washes and ceramic formers. The unique design of elements allows rapid, natural cooling of resistor bank. Castors are provided for easy mobility.Constant Current and Rate of Discharge : The resistor bank has adequate trimming facility (coarse and fine) to maintain a constant current against falling voltage during discharge operation. D.C. contractors / Circuit breakers or knife edge sitches are used for switching depending on clients preference. The Rate of Discharge can be accurately controlled and monitored in this system which is a distinct advantage over other conventional methods of Discharge.Our Clients for Discharge units :1. Tata Electric Company, Thermal Power Plant I. Mumbai.2. Nuclear Power Corporation.(KAPP). Kakrapara.3. Standard Batteries Lts. Testing Div. Kanjur, Mumbai.4. I.P.C.L Nagothane.5.

Neutral Earthing Resistors for fault protectionA Neutral Earthing Resistor restricts the flow of current during an earth fault on an AC distribution system. It is connected between the neural point of a transformer or generator and earth. Although a Neutral Earthing Resistor will probably be active for just a few seconds during its operational life, it must offer dependable protection at all time in case of fault. Application can be found in power distribution, mining and industrial installations, indoors and outdoors. Iresco Neutral Earthing Resistors are designed to cope with the most climatic conditions and saliferous atmospheres. These resistors offer distinct advantages of durability and reliability. They meet IEE Standard 32-1972.SPECIFICATIONS :Capacity : A Neutral Earthing Resistor has a resistance value specified to limit the fault current within a system to a pre-determined value which is sufficiently low to prevent damage yet high enough to operate fault-clearing relays.Each system is designed according to current and timeratings, which are specified to be compatible with the protection switch gear. The range available includes; current to 3000 amps; time to 60 secondsl and system voltage to 66kV. The resistance value is precise and determined at the manufacturing stage, remaining constant throughout life.Materials : Iresco Neutral Earthing Resistors are made from tough steel grids of a high quality iron-chrome-aluminium or AISI 304 SS allow. They are non-corroding and offer good electricity stability.Insulation : Mica and ceramic insulators throughout.Ventilation and Cooling : Neutral Earthing Resistors and contained in fully protected and ventilated steel enclosures.Construction : Neutral Earthing Resistors consist of wire or plate grid elements mounted ceramic insulators with a filamic tube between their base and the plated high tensile steel support rod. Adjacent elements are bolted together to provide connections unaffected by heating and cooling cycles.Groups of elements are mounted together between end plates to form a bank. Banks are then connected in series or parallel to provide the current and ohmic value required. Adjacent banks are insulted from each other and the metal framework.All interconnections of banks are in solid copper strip. Connection to the HT side is made via an entrance bushing and to the earthside via a brass terminal stud, suitably rated. Standard enclosures provide a minimum of IP23 protection.If required, insulated cable boxes are available for incoming and outgoing cables on the side or top of the unit, with removable covers and gland plates. These Neutral Earthing Resistors are virtually maintenance free...
