EI19 1000:2 2000:2 Low Frequency Current Transformer Lamination
Transformer
1.Product Description
The EI19 Low Frequency Current Transformer is a compact and
efficient transformer designed for low-frequency current
measurement and monitoring applications. Featuring an EI19 laminated iron core, it offers high magnetic
permeability and low core loss, ensuring accurate and reliable
current sensing. Its robust construction and wide frequency range (typically 50Hz -
400Hz) make it ideal for use in power distribution systems, energy
meters, and industrial equipment. The EI19 design provides excellent linearity and low phase error,
making it a dependable choice for precise current measurement in
low-frequency environments.
The impedance of voltage transformer itself is very small. Once the
secondary edge is short-circuited, the current will increase
sharply and burn down the coil. Therefore, the original side of the
voltage transformer is connected with a fuse, and the secondary
side is grounded reliably, so as to avoid personal and equipment
accidents caused by the high potential to the ground when the
insulation of the primary side and the secondary side is damaged.
Voltage transformers used for measurement are generally made into
single-phase double coil structure, and the original side voltage
is the measured voltage (such as the line voltage of the power
system), which can be used in single phase or connected into two
V-V for three phases. The voltage transformers used in the
laboratory are often tap at the original edge to meet the needs of
measuring different voltages. Voltage transformer for protection
grounding also has a third coil, called three Coil voltage
transformer. The third coil of the three phase is connected into an
open triangle, and the two leading ends of the open triangle are
connected with the voltage coil of the grounding protection relay.
