Answer / dinesh lokhande

Choke is basically a inductor whose property is to react
for instantaneous change in current through it. In tube
light ionisation of gas is possible only at higher voltage
of around 1000 V. However our supply voltage is 230V. hence
starter which is a bimetallic strip act as a interuppter
for current flowing through choke. Change in current
results in development of high voltage at inductor terminal
which is in parallel with ionising terminals.Hence gas
ionises and tube glows in that fraction of seconds of
current interuption.

Answer / simon

Choke=It's a type of a step down x-mer up to 100v a.c.
Starter=produces surge current for tube.

what is rms value?

WHAT SHOULD BE THE BEST CURRENT RATINGS (PRIMARY / SECONDARY)FOR A CT INSTALLED AT THE INCOMING 11KV PANE? WILL IT BE CALCULATED ON THE BASES OF MAXIMUM DEMANT VALUE OR ON SUM OF ALL TRANSFORMER'S KVA? NOMALLY MAX DEMAND REPRESENT THE MAXIMUM OPERATING LOAD OF THE PLANT AND TOTAL KVA OF (SAY 5 NUMBERS TRANSFORMERS) REPRESENT THE CONNECTED LOAD. WHICH i.e. MAX DEMAND KVA OR CONNECTED KVA ARE BETTER TO USE FOR CT CURRENT CALCULATION? PLEASE ANSWER.
