Series Inductive Voltage Transformer for GIS
Product Detail

Product introduction:
The inductive voltage transformer is used for GIS, it is widely applied to the nominal system voltage is 66-1000kV, and 50/60Hz frequency in power system, for the secondary measurement apparatus, protection and control device provide voltage signal. The product has three-phase and single phase two kinds of structure, in order to facilitate the GIS customer substation site handover test, our company developed the isolated structure of the GIS VT product. When power frequency withstand voltage through the disconnector directly to the VT and GIS isola tion, and enhance the efficiency of acceptance test on site.

Product features:
●Gas optional: SF6 , Mixed gas or Clean air
●Epoxy pouring insulator(Spacer): Provided by GIS manufacturer or purchase from customer-specified suppliers.
●Gas charging valve:  Provided by GIS manufacturer or purchase from customer-specified suppliers. 
●Partial discharge sensor: According to customer demand selective installation.
●Operating box: The box of three phase products placed at the bottom and single phase products places at the side, can be achieved both manually and electrically operation ways. 
●Open and close indication: Using the fish eye type indication, consistent with the GIS.

Development of an Outdoor Integrated Low - Voltage Current Transformer
Development of an Outdoor Integrated Low - Voltage Current Transformer
In power grid construction, line losses reflect planning, design, and operation management. They’re key for evaluating power systems. For refined low - voltage transformer area line loss management, accurate line loss counting is critical. So, solidifying basic data, ensuring data accuracy, and proper original data collection matter for analysis. We must also optimize factors affecting collection accuracy, make preventive measures, and boost refined line loss management.1 Current Status of

Ratio Trial Verification Method for Current Transformers
Ratio Trial Verification Method for Current Transformers
Fellow electric power calibration workers, you must have encountered this situation: The nameplate of an outdoor current transformer has been tormented by wind, sun, rain, and freezing, to the point where the transformation ratio is indistinguishable! Don't panic, we have a solution - use a current transformer calibrator and through the “transformation ratio trial calibration method”, we can figure out the actual transformation ratio and errors clearly. Here, taking the SHGQ - DC typ
