Product Details
RSHL-300A CT VT Testing Equipment High Accuracy 0.05 class 300A
Standard Current Transformer
Product Description
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.
Ambient temperature:0°C -- +40°C; Relative humidity should be
greater than 80%
- 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.
