  We are engaged in offering of Load Banks for Industrial Automation. Known for its compact structure and high level of efficiency, Load Banks are highly appreciated in the market. What Is Load Bank : Load banks are compact units that are coupled to the output of your power generation system such as diesel generators, gas turbines or UPS and battery systems Load banks are dummy loads, designed to simulate the plant load and prove the design, performance and the capacity of the system, without interruption to the normal running of your plant WHAT DOES A LOAD BANK DO : Generators are usually rated to supply sufficient power to a plant or building, based on the maximum demand required. Sufficient plant loading is not always available to safely load generators. Under loading of the engine will cause a high wear rate due to insufficient fuel combustion and loss of lubrication resulting in cylinder bore glazing and fouling of exhaust ports and valves. Running the generator without load will not prove its performance or power capacity. Proper and controlled loading is therefore essential. It increases diesel engine life by up to four times and improves the efficiency by ensuring that the engine has sufficient loading at all times. It proves the rated power, proves system operation, controls integrity and communications of your power system. It maximize battery life in UPS systems by regular loading and discharging. Specifications : Power ratings available : 1KW / 2KW / 5 KW / 10KW Voltage Primary : 440V AC 3Phase/ 220V AC Single phase /220V DC Enclosed in cabinet with Steps provided for loading, meters provided for each phase & terminations brought out on Banana terminals

Voltage utilized in industry are of either resistive, inductive or capacitive types these provide various types of power factor and the power system behaves accordingly. Resistive load banks are used to provide braking effect or for heat dissipation.

Features : WE HAVE EMERGED AS ONE OF THE TRUSTED ORGANIZATION ENGAGED IN FABRICATING LAPT PANEL BOARDS TO THE CUSTOMERS. OUR RANGE IS WIDELY APPRECIATED BY THE CLIENTS FOR ITS EFFICIENT FUNCTIONING AND APPLICATION IN VARIED INDUSTRIES & SECTORS. MOREOVER, WE CONSIDER THE MARKET DEMAND WHILE FABRICATING THESE PANELS. FOLLOWING ARE THE FEATURES OF THESE PRODUCTS : • Shock-proof exteriors • Sturdy construction • Reliable performance   An LAVT panel is a cubicle which houses a Lightning Arrester (Surge Arrester), Surge Capacitor, and Voltage / Potential Transformers for a Phase Isolated Bus Duct. Lightning arrestor is there to provide protection against any surges in voltage, hence the name lightning arrestor, it is a device that safely diverts any surge in voltage "away" from your plant therefore protecting your equipment against overvoltage conditions. A capacitor is connected in parallel with the lightning arrester for enhanced protection as well. The voltage transformer will probably be for either protection purposes or for some instruments on your system.If you have a voltmeter or wattmeter etc on the panel then it is probable that it's supply is derived from the VT. A VT transforms the primary voltage, in this case 11kV down to a low voltage (probably 110V) to give an accurate representation of the system volts, which can be incorporated into protection devices and measuring devices. LAVT Panels are used in all high voltage power Plants wherein for protection of the Alternator. This unit is phase isolated and is mostly connected to the bus duct.

When an induction motor’s rotor is turning slower than the synchronous speed set by the drive’s output power, the motor is transforming electrical energy obtained from the drive into mechanical energy available at the drive shaft of the motor. This process is referred to as motoring. When the rotor is turning faster than the synchronous speed set by the drive’s output power, the motor is transforming mechanical energy available at the drive shaft of the motor into electrical energy that can be transferred back to the drive. This process is referred to as regeneration. Most AC PWM drives convert AC power from the fixed frequency utility grid into DC power by means of a diode rectifier bridge or controlled SCR bridge before it is inverted into variable frequency AC power. Diode and SCR bridges are cost effective, but can only handle power in the motoring direction. Therefore, if the motor is regenerating, the bridge cannot conduct the necessary negative DC current, the DC bus voltage will increase and cause an overvoltage fault at the drive. More complex bridge configurations use SCRs or transistors that can transform DC regenerative electrical power into fixed frequency utility electrical energy. This process is known as line regeneration. A more cost effective solution can be provided by allowing the drive to feed the regenerated electrical power to a resistor which transforms it into thermal energy. This process is referred to as dynamic braking.
