RSHL-300A CT PT 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
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.
