TH2829X Series Operation Manual Chapter 6 Transformer Single-machine Test
TH2829x606
On this page, the following parameters can be set: turn ratio, primary inductance,
secondary inductance, primary DC resistance, nominal value used for judge and
display, high and low limits, high/ low limit mode
6.3.1 LMT MODE
This zone displays the compare deviation modes of the current transformer: ABS
(Absolute value) and ∆% (percent).
Move the cursor to LMT MODE: the following soft keys will be displayed.
ABS
∆%
6.3.2 Parameter column
The parameter column is made up of primary turn, secondary turn, primary
inductance, leakage inductance, Cx , Zx, ACR and DCR, each of them has 3
variables: nominal value, low limit and high limit.
Move the cursor to the parameter table and input nominal value, high and low
limits. The high limit should be larger than the low limit. Note: the nominal
value’s unit has the memory function, if the unit needs to be changed,
please press the multiplying unit in the soft key zone. If the multiplying
unit is not necessary, please press [ENTER] key.
