04-2016 | Monitoraggio cavi EAF & LF a Bhushan Power and Steel Limited

BRAR India successfully concluded the measurement of water cooled cables at Bhushan Power and Steel Limited.

 

Introduction

M/S BPSL has started replacing cables from 2009- 2010 and recently noticed unpredicted failures in Cables causing stoppage of Furnace.

M/S BPSL contacted M/S Brar India Pvt. Limited to submit the detail report of all cables in operation. M/S Brar India Pvt. Limited deputed team with Telemaster System and successfully made measurement of all cables on installed positions.

 

At present 4 nos. of EAF and 4 nos. LF are in operation at M/S

Bhushan Power and Steel Limited. EAF 1 , EAF 2 and LF1, LF2 were commissioned in 2007 and remaining in 2010. Two EAF

commissioned in 2007 are powered with 60 MVA Furnace

Transfomer and remaining two with higher capacity Trafo of 84 MVA.

 

Measures

Brar India team with Telemaster System and successfully made measurement of all cables on installed positions.

Measures with Telemaster at BPSL made in 3 steps: 1.Clamps connection 2.Sensor assembly 3.Measure

Taking into consideration that in this case the nominal resistance value of a new water cooled cable is 57μὨ (Cable 3000 Sq.mm, 9800mm long) and it is usually suggested to change the cable when the resistance value becomes more than 85μὨ (150% of the nominal value), from the measurement values in EAF 1, 2,3, 4 that cables marked RED were to be replaced immediately.

 

Final Consideration / Recommendation

Thanks to these measures BSPL could arrange a preventive maintenance plan to change the cables with high resistance and avoid unpredicted failures in Cables causing stoppage of Furnace.

Furthermore BSPL confirmed they now keep records for each water cooled cable, schedule water cooled cables replacements well in advance avoiding furnace stop, increase productivity, prevent overload pf other cables in parallel and save power losses.

 

 

TELEMASTER is the new innovative system developed by BRAR to monitor the water cooled cables electrical electric performances, predict the failure in advance and reduce power losses.

Today more than 500 water cooled cables of 45 furnaces has been monitored by the TELEMASTER.
