Product Description

Transformer Load Capacity Loss and Short-circuit Voltage Testing Equipment


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.

II.Function
We can measure a variety of distribution transformer, power transformer capacity instead of the additional power. It is more convenient and efficient.
ombined 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.
ll 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.
The maximum voltage is up to 750V and the maximum current is up to 100A. It is equipped with protection circuit.
The voltage and current range can be very flexible and easy to expand.
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.
According to the test results of no-load and load loss, it can automatic presume the three-phase oil immersed distribution transformer and power transformer's performance levels as the reference (this instrument is currently only available for three-phase oil immersed transformer and power transformer performance level code. Others are invalid.)

III.Definition of Testing Transformer 
Transformer capacity and characteristic test is the professional test. There are many setting part and items of testing method.
1. Tap
    In the transformer with topped winding, every tap in this winding stands for a fixed turn number of windings in this tap, which also means a fixed turn number of windings between this tap winding with other constant windings
2. Principal Tapping
Tap corresponds to the rated parameters. Attention: The data of load/no-load loss and no-load current is the data of transformer under the principal tapping (except for appointed other taps)
3.  On-load Tap Charger
   It is the device that is used to change the position of tap of transformer winding under operating with excitation or no-load.
4. Off-circuit Tap Charger
    It is the device that is used to change the position of tap of transformer winding under operating without excitation.
5. No-load Loss (commonly known as: iron loss, iron loss)
   When rated voltage (tapped voltage) under rated frequency is applied to terminal of one winding and open circuit of other windings, it is the active power.
6. No-load Current
When rated voltage (tapped voltage) under rated frequency is applied to terminal of one winding and open circuit of other windings, it is the root average of current.
Note 1: For three phase transformer, it is the average of current of three phase terminals.
Note 2: Generally use the percent of current to display. For the multi-winding transformer, it is based on the winding with max rated capacity.
7. Load Loss (Short Circuit Loss/Copper Loss)
It is the active power in one pair of winding, when rated current flows through the line terminal and short circuit of the other terminal under the rated frequency and reference temperature. If it has other windings, please make them open circuit.
Note1: For the double winding of transformer, there is just one pair of windings and one value of load loss.
       For multi-windings of transformer, there are multi pairs and value of loading loss.
Note2: When the capacity of the two windings, it should be based on the rated current of the windings with the lower rated capacity, and appointed to the reference capacity.
8. Total Loss
    The sum of load loss and no-load loss.
9. Short Circuit Impedance
Generally, short circuit impedance is the impedance of the pair winding.
Under the rated frequency and reference temperature, the equivalent series impedance of one pair windings between the terminals of winding is
Z=R+jX(Ω). Now, the terminal of the other one need to short circuit. If there are other windings, they need to open circuit.
Note1: For the transformer with tapped windings, short circuit impedance need to appoint the tap, if there is no special instruction, it is the principal tap. For the three phase transformer, it means the impedance of single phase.
   Formula is suitable for the three phase and single phase transformer.The relative value is equal to the ratio between the voltage and rated voltage (tapped voltage) when operator wants to get the rated current (tapped current) in short circuit test. This voltage also called the short-circuit voltage of this pair windings.  It is generally expressed as a percentage.
