0.05 Class 300A Standard Current Transformer With 1 Year Warranty

RSHL-300A CT VT Testing Equipment High Accuracy 0.05 class 300A Standard Current Transformer

Product Description

• Purpose

It can be used as a standard instrument for the verification of grade current transformers or for other precision current measurement

The function of the transformer is to reduce the ac voltage and the large current in proportion to the value that can be directly measured by the instrument, so as to facilitate the direct measurement by the instrument, and at the same time to provide power for relay protection and automatic devices.The transformer can measure the voltage, current and electric energy of the primary system in coordination with the measuring instrument and measuring device.Together with relay protection and automatic devices, it can constitute electrical protection and automatic control for various faults of the power grid.It is part of the component of transformer integrated test bench. 

• Conditions of use

Ambient temperature:0°C -- +40°C; Relative humidity should be greater than 80%

• Use and maintenance

• Please be careful not to seriously collide with the machine due to its epoxy resin casting.The machine should be moisture-proof and soiled.And the surface of the instrument should be wiped with a clean cloth before the test to prevent creepage along the surface
• In the process of measuring the current,do not allow sudden interruption in the current,so easy to cause remanence in the iron core,easy to cause a large error in the measurement.
• Special attention should be paid to the fact that in the process of measurement,the secondary coil loop should be firmly grounded,and no open circuit should be opened to avoid the generation of high voltage,so as not to harm people.
