An Arcing Fault is the flow of current through
the air between phase conductors or phase
conductors and neutral or ground. Concentrated
radiant energy is released at the point of arcing
an a small amount of time resulting in Extremely
High Temperature.

EXOTHERMIC WELDING- For all buried permanent
connections as per IEEE 837 / NBC 2017

• Main earthing wire connections shall be
• Be mechanically electrically sound
• Be protected against damage, corrosion and
  vibration
• 100 contact surface area is must
• Be secured at the earth electrode

12
EXOTHERMIC WELDING- Permanent Jointing solution
These cavity can be designed on customize basis
as per the type of joint is required.
Also the dimension of the conductors which needs
to be joint in a kind of jointing.
We are the manufacturer and can offer any kind of
joint type as mentioned below

Most Efficient Joint Process
It is efficient and superior to all existing
surface to-surface mechanical retention
connectors.

• The 100 of lightning energy breaks down as
  follows
• a) 50 of the lightning current will flow
  through the ground
• b) 50 of the lightning current will flow over
  the connected metal parts out of the
  building
• about 10 to the water pipe (metal)
• about 10 to the gas pipe (metal)
• about 10 to the oil pipe (metal tank)
• about 10 to the sewage pipe
• about 10 to the power suppliers incoming feed
• max. 5 or 5 kA shared across all data lines

• Lightning Protection Standard use in India
• (IS2309 Now IEC 62305-5)NBC2016
• Working Principle Angular No Compromise with
  Design Max Protection 30Mtrs from One
• No Product warranty from Manufacturer
• High Maintenance Require
• Earthing below 10.00 Ohm

Lightning Risk Assessment Study is actually the
measure of risk of a lightning strike and
probability of damages. As Per IEC62305-2.

• All these calculations are based on
• Lightning strike density in that particular
  area(provided byOMV i.e.Ng 8),
• Danger for people,
• Occupation coefficient of structure,
• Relative location of site,
• Fire Risk,
• Associated services,
• Electrical Lines,
• Lightning Protection Level,
• Surge Arrestor and
• Dimensions of installation.
