I1 : Primary current (AT)
RL : Load resistance (Ω)
Eo : Output voltage (mV rms)
Before Using Current Transformers Low Current Type
• The core may be damaged if applied with a strong impact. Carefully avoid dropping or applying any other
strong impacts.
• Preliminary study is needed with regard to heating by current conduction.
• Do not use the current transformer opened between secondary output terminals.
In the worst case, heat build-up in the magnetic core may occur, resulting in dameges to the parts by the melting
of coil due to this heat.
