Product Description
ZBW packaged substation, also known as prefabricated substation. It meet GB17467-1998 high and low voltage prefabricated substation and IEC1330 standards etc. As a new type of power supply and distribution device, has more advantages than traditional civil substation. Such as smaller size, smaller floor area, compact structure, flexible movement, which greatly reduce period and area for construction in site, also the construction cost. Meanwhile, prefabricated substation is easy to be installed at site , can realize rapid power supply, almost maintenance free. Most particularly, it is placed at load center so that reduce power loss effectively to improve power quality, enhance the reliability of power supply and also is significant for distribution network transformation.
This substation fulfills the functions such as transformation of energy, distribution, transmission, metering, compensation, system control, protection and communication.
The ZBW prefabricated substation is composed by the high-voltage switchgear, low-voltage distribution panel, distribution transformer and enclosure. The high-voltage switchgear adopts air load switch and the transformer is dry-type or oil immersed type. The substation adopts good ventilation structure with elegant appearance and good heat-insulating performance. The temperature rise of the compartments caused by the outdoor solar radiation can be reduced to within the lowest limits on account of the upper and lower ventilation windows. The forced ventilation device and the temperature auto-controlled device should be installed in the substation. The systems of control, protection, live display and the lighting are equipped in each separate unit.

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.

Specification:
A transformer is an electrical device that transfers electricity from one circuit to another with change in voltage, current, phase or other electric characteristics. Transfer of electricity from one circuit to another is purely by magnetic coupling, without relative motion of any part. Transformers are essential in high voltage power transmission providing an economical means of transmitting power over large distances. These are used for both industrial and commercial purposes. Ganpati Electricals (P) Ltd. Is a well-known and trusted supplier of a wide range of transformers of Crompton Greaves Limited.
Types of Cooling:
1. Oil-cooled Transformers: These are totally maintenance free and can be used both indoor and outdoor. Oil-cooled transformers are available in two versions namely (a) with Off-load tap changer and (b) with ON-load tap changer.
2. Dry or Cast Resin Type Transformers: These are air-cooled, having an epoxy resin encasing the windings. These are ideal for indoor installation. However, because the moulds for casting the coils are available only in fixed sizes, the design of such transformers is less flexible; this may increase the cost of customized dry transformers.
Types of Transformers:
1. Power Transformers: These convert an AC voltage and current to a different voltage and current with great efficiency.
2. Distribution Transformers: These are generally used in electrical power distribution and transmission and can withstand overloads.
3. Special Transformers: These include Furnace Transformers, Loco transformers, Traction Distribution Transformers, Trackside Power Transformers.
4. Distribution Unit Substations: These may be of Mini & Micro Types used in Substations.
5. Weather-proof Transformers: If required by client, we can also provide weather proof enclosure for the transformer.

We manufacture highly efficient and accurate resin cast potential transformers. These resin cast potential transformers are used in ac circuits, for the purpose of measuring large voltages. Their main function is to reduce the supply voltage to a small value so that it can be easily measured with standard low range ac instruments of moderate size and capacity. There are many advantages of using resin cast potential transformers for range extension of ac meters. We also offer resin cast potential transformers of dual purpose metering & protection that are also commonly used.
