TIP serijos srovės transformatorius

The TIP series transformers are current transformers designed for use as energy
monitoring products.
They may be used as measuring transformers or protection transformers:
• Measuring transformer:
Short circuiting in terminals or connection to ground may be done using the
fast-on or connecting two cables to the same terminal.
• Protection transformer:
When a current transformer is is used to create a current for protection relays,
its characteristics are different from those of measuring transformers.
In fact the magnetic circuit of the measuring transformer will be saturated with
Class 5P in primary currents, whereas in the protection transformers, the value
of the secondary currents must follow the increment in the primary currents,
which may reach 10-15-20 In, to guarantee the activation of the relay in the
event of an unforeseen power cut.
It is important not to load with a power (P) greater than that indicated to ensure
that the current transformer saturation value is not modified.
P = R * I2
P= Load connected to the current transformer.
R= Relay resistance + cable resistance
I = Nominal secondary current of the current transformer
