(Static discharge continued from page 24)
for the excess charges to rapidly
discharge themselves is created,
leading to a static spark discharge.
If a combustible atmosphere is
present in this space, ignition of the
atmosphere is very probable. Under
ambient conditions, average field
strength of 30 kilo-volts is capable of
causing the electrical breakdown of
air over a spark gap of 0.8 inches.
Standards Governing Static
Control
As outlined earlier, regulators
are extremely cautious about the
ignition hazards presented by static
electricity in tank-truck product
transfer operations. Three standards,
in particular, provide clear guidance
on what precautions should be
taken: NFPA 77, API RP 2003 and
CLCTR: 50404 state that grounding
of the tank-truck should be the first
procedure carried out in the transfer
process.
Grounding effectively creates
an electrical circuit that connects
the tank-truck to earth and it is this
connection to earth that prevents
static charges from accumulating
on the tank-truck’s container. The
reason the charges can transfer from
the truck to earth is because earth
has an infinite capacity to absorb
and redistribute static charges, with
the positive effect of removing the
ignition source from a potentially
combustible atmosphere.
The electrical resistance of this
circuit from the truck to the ground
source that is in contact with the
earth is a key performance indicator
of the entire grounding circuit’s
capacity to provide a safe product
transfer operation. NFPA 77 and API
RP 2003 state that the resistance
in a healthy metal circuit should
never exceed 10 ohms, therefore
the entire circuit between the
truck and grounding point should
be measured and be equal to, or
less than, 10 ohms. If a resistance
above 10 ohms is measured this will
indicate problems with parts of the
grounding circuit, including the tank-truck connection, the ground point
connection or the condition of the
conductor cable.
Tank-Truck Grounding Systems.
The standards state that a
grounding system, which can
measure and monitor resistance
in the grounding circuit, can be
utilized. The system should verify if
the ground connection to the tank-
truck is complete before loading or
unloading is initiated. The CLCTR:
50404 standard recommends 10 ohms
or 100 ohms
An additional recommendation in
NFPA 77 and API RP 2003 calls for
interlocking the feed system (e.g.
pump) with the grounding system so
that if the grounding system is not
connected to the tank-truck, product
cannot be transferred. In general,
interlocked grounding systems will
complete the grounding circuit when
the driver connects the clamp of
the grounding system to the tank-
truck and the system sees a circuit
resistance of 10 ohms or less.
Cummins introduces
engine lineup
Cummins Inc. recently introduced
its medium and heavy duty engine
lineup for 2013, saying it will meet
federal 2014 GHG/MPG rules in
January 2013 and deliver up to a
2-percent fuel-economy improvement
over today’s engines.
The improvement in fuel economy
will come by using the “same proven
high-pressure common rail fuel
systems, VGT turbocharger and fully
integrated electronics” as its existing
engines, company officials said.
However, base engine improvements
will increase miles per gallon by
reducing the parasitic loads on
engines through high-efficiency
water, fuel and lube pump systems,
the company added.
“Customers can count on
Cummins,” said Rich Freeland,
