My country's power system implements a two-part tariff: In addition to the cost measured by the metering device, a basic electricity fee is charged based on the transformer capacity; larger users also need to pay a one-time capacity expansion fee when commissioning their transformers. With the development of the power industry and the increase in electricity consumption, privately owned and contracted transformers have gradually occupied a considerable share of distribution transformers. This has led to various fraudulent methods employed by individuals to reduce their electricity bills and increase their usage (mainly altering or replacing transformer nameplates). The power sector struggles to effectively supervise this, and some users steal hundreds of thousands of yuan in electricity fees annually.
This instrument is a multi-functional measuring instrument, equivalent to two conventional testing instruments: a transformer capacity tester and a transformer characteristic parameter tester. It can precisely measure a series of power frequency parameters of various transformers, including capacity, type, no-load current, no-load loss, short-circuit (load) loss, and impedance voltage.
This product has many advantages, including small size, light weight, high measurement accuracy, good stability, and simple operation. It can completely replace the previous method of measuring transformer loss and capacity using multiple meters. The wiring is simpler, and the testing and recording are more convenient, which greatly improves your work efficiency.
