The Model 4062 is a frequency adjustable switch mode
current injection source that is in effect the bigger brother
to the 200 VA injection unit above.
It is used to drive variable voltage and current magnitudes into an earthed or passive load loop at maximum power
continuously if required.
Typically the earth test loop / circuit consists of the earth grid
under test connected to a remote earth grid through an earth
path in the ground. To complete the loop, a return connecting
path isolated from earth, usually an ‘out of service’ feeder or
separate injection line is also used. The test current is driven
around the loop by the secondary winding of the Model 4063
Coupling Transformer which is inserted into the loop.
Frequencies from 40Hz to 70Hz can be selectively generated
by the 4062 to avoid interference with background line
frequency. Voltage drops generated by the injected current
around the earth loop are measured with a frequency
selective multimeter fixed to the current injection test
frequency.
Measureable results over the test landscape can be profiled with the 4025E or 4031 frequency selective
multimeter. Both the 4025E or 4031 and the 4062 Injection system have a GPS function which is used
for position location and phase synchronization which frees up the need for phase reference cabling
during current split measurements and also provides relative positioning information so that the operator
may choose the best line of potential measurement during EPR tests to avoid mutual coupling/induction.

As with the 200VA unit the 4062 also has a remote monitoring and control feature available which allows
the user complete control of the injection system via a 4G / LTE network.
The communication network gives the operator direct access to the 4062 and it’s operating functions by way of an embedded web server which has been integrated into the 4062.
Comes with Trolley handle and wheels for ease of transportation.
Only 15kg or 33lbs.
