Transformer Capacity and Loss Tester Transformer Oil Tester I  Introduction Transformer Capacity Testing Instrument is specialized in bad power users evading basic electricity secretly adds capacity problems and is a high precision instrument specially used for the measurement of the transformer capacity and parameters. This product uses color LCD monitor, English display, simple and quick menu operation, man-machine interface is friendly. The internal of the instrument has a rechargeable battery and it can work without external power source. A fully charged battery can be continuously measured more than 100 sets. In addition, the instrument can provide three-phase precise 50Hz sine wave AC test power without the external three-phase test power, the pressure regulator, up flow reactor and other auxiliary equipment in measuring the capacity and transformer load loss, thus greatly improving the efficiency of the work. This is a multi-functional measuring instrument, which is equivalent to two common devices: activity transformer capacity tester and transformer parameter tester. It can be used for test transformer capacity, model, no-load current, no-load loss, load loss, impendence voltage and so on. This product has many advantages such as small, light , high accuracy, stability, simple operation and so on. It can replace the multi-meter method to measure the transformer loss and capacity with simple wiring and convenient testing so that the work efficiency can be greatly improved. Function 1. We can measure a variety of distribution transformer, power transformer capacity instead of the additional power. It is more convenient and efficient. 2.Combined with the power, voltage, boost up flow and other equipment, it measures various transformer no-load current, no-load loss, impedance voltage, load loss and so on. 3.All results are automatically carried out relevant correction. You only need to input the related parameters (such as temperature, load adjustment coefficients), then the instrument can automatically correct such as waveform deformity correction, temperature correction, correction of non rated voltage, rated current correction. 4.The maximum voltage is up to 750V and the maximum current is up to 100A. It is equipped with protection circuit. 5.The voltage and current range can be very flexible and easy to expand. 6.It has large screen, high brightness LCD display, English menu and operation tips, friendly man-machine interface and wide temperature, brightness adjustable type LCD screen, which can adapt to the different temperature.

Modulating Capacity Transformer Special Transformer Modulating capacity transformer is one kind of distribution transformers, which has two capacities ( one is small , another one is large) and can adjust according to the load size. The changing of high voltage winding connection mode, the conversion of low voltage winding parallel series and the adjustment of every connection are finished by special no excitation modulating capacity switch. Meanwhile, when large capacity is adjusted to small capacity, no-load loss and no-load current will be reduced because the increasing of low voltage turns and the decrease of coreâ??s magnetic flux density reduce unit loss of silicon steel, thus reaches the purpose of lowing loss and energy-saving. Double voltage distribution transformer has one small and one large voltage, and can adjust according to electric grids voltage. The conversion of high voltage winding parallel series and the adjustment of every connection are finished by special no excitation modulating capacity switch.   General introduction  SZ11-T load modulating capacity transformer is one kind of distribution transformers with new technology and energy-saving. It has two kinds rated capacity, one is small and another one is large, and the operation mode of these two capacity can be automatically converted which solves the problem of transformersâ?? large loss caused by relatively large changes of 10 kV distribution grids seasonable magnitude, and also solve the operational maintain problem because capacity must be adjusted by hand after the outage of no-load modulating capacity transformer power . Modulating capacity transformer not only suits rural electric grids which seasonable magnitude changes are relatively large, but also suits downtown, development zones, industrial zones and other distribution work area where circadian load changes are obvious.  Working principle Load modulating capacity transformer is adjusted by the intelligent controller externally modulating- switches, thus completing the convert process of high capacity and low capacity, more details as below: intelligent controller determines the current load size by detecting transformers voltage and current of low voltage side; determines related constraints based on the capacity setting value; if meet the setting conditions, intelligent controller will issue the corresponding control commands to load modulating capacity switch, then modulating capacity switch can finish the star ,angle change and the parallel series convert of transformer s inner high voltage winding, low voltage winding; completes the process of capacity adjustment under conditions with power.
