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.
