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.

We have 2 Nos. Transformer with the capacity of 2000KVA and 1250 KVA and currently using only one 2000KVA T/R during operational hours while non- operational hous 1250 KVA T/R also used to reduce T & D losses. Similarly, 2 capacitor bank of 500KVAR and 300 KVAR also installed to balance reactive power. Now problem is around 1000 KW load PF is not maintaning 0.99 as 350 KVAR capacitor is in healty condtion. Now the PF is maintain 0.95 to 0.96.
