Current transformers are basically used as it is not possible to use line current directly for measurement and relaying purpose due to its high value and insulation problem. CURRENT TRANSFORMER which is widely known as 'CT' is a piece of electrical equipment which converts line current ( primary current ) in to small standard current values which are suitable for the devices to which it is connected e.g. measuring instruments, meters, protection relays.
Yokins manufactures metering, protection Class LT CTs in tape wound and resin cast constructions as required. CTs are available from 5A to 4000A with an accuracy of 0.5% & 1% as per IS 2705. Standard secondary current is 1A & 5A.Toroidal (round) and rectangular CTs are manufactured to suit various busbar sizes.
In today's world of cutthroat competition and market driven economy, every manufacturing unit is facing two foremost challenges.Rising energy cost and urgent need to be "Globally Competitive", not only to grow but even to survive.
Electricity consumption plays a major role in deciding the production costs of any product oriented industry. The major load in any industry is its machinery.
If you do not measure, you cannot improve - so goes the saying. Which means measurement is the first and necessary step towards improvements
How good it would be if you can know :Daily Unit Consumption (kWh or kVAh) of each & every machines with timings.You will be able to calculate the Shift consumption of each and every machine.Run-Hour & on-Load-hour of your machinery, by knowing the full load (Ampere) the machine takes while production is going on & no load (Ampere) when the machine is running idle. This can help you analyze how much work is been done on that particular machine.This will help you in knowing the electricity consumption incurred in producing a single piece from the machine. Also, you can analyze the efficiency of your machine Operator.
Moving Coil Instruments are suitable for the measurement of DC currents and voltages. These are permanent magnet (Alnico high flux density) type with pivot-jewel suspension. The movement is having high torque to weight ratio and linear one with knife edge pointer for accurate reading. The design and construction of instruments is most modern. Sturdiness, simplicity, sensitivity and rigid quality control ensure these movements for high grade performance under adverse conditions of shock and vibration. All instruments are housed in ABS moulded dust proof cases with zero adjuster accessible from the front.
