Lightning : a danger for planes!
On average every civil transport aircraft is struck by
lightning in flight once a year
The risk of strikes by lightning is increased in rainy zones,
at approximately 4000 meters and between -5°C and +5°C
During a strike by lightning, the lightning does not stop on
the plane but sweeps it to continue its way in the
atmosphere with a point of initial entrance and a point of
final exit
Direct effects of lightning
Strikes
 They are caused by the effect of the discharge or by the
conduction of the lightening strike current (up to 200 kA!)
 Types of the damage:
 Thermic with perforation of walls by fusion
 Dynamic with rise of pressure which generates a
destructive shock wave for the cabling and the
dissimilar and composite materiels.
 Electromagnetic which perturbs the on board equipment

Why measure the
bonding resistance ?

A plane with a structure and a metal envelope (aluminium)
constitutes an excellent protection against lightning strikes
provided electric continuity is insured

Connection of dissimilar materials can cause a weakness in
the electric conductivity and prevent the effective
discharge of electric loads received by the plane

The bonding of these surfaces becomes indispensable and
thus the control of this bonding and the continuity
RCP2A
The milliohm meter RCP2A is a measuring device of
resistances from 0,001 m to 6000 m  with currents of 0.1
A, 1 A or 10 A.
Presented in a fibreglass and resin polyester box of small
dimensions (340x120x220 mm) with a weight of 4 kg, its
ergonomics allows the user to use it either placed on the
ground or across one’s shoulder or chest.
A wide back-lit LCD display combined with an intuitive
keyboard ensure simple and easy operation.

Method of measure
In order to make low resistance measurement with a high
precision, the RCP2A uses the 4 wire Kelvin method.

2 wires are used to connect a constant current source to the
resistance to be measured

2 additional wires are used to measure the difference of
potential directly to the terminals of the device under test.

With this method, the resistance of the measuring leads
does not introduce any error.
