Full power tables
Simultaneous three phase CT burden and ratio test
Current transformer demagnetization
Turns ration testing of potentional transformers
Harmonic analysis up to 39th harmonic
On board data collection and management
600 Volt Cat IV, 0.04% accuracy
Instantanious Analysis
of All Power Parameters
Gold Miner performs circuit analysis and wiring verification on
ALL phases for both Primary and Secondary circuit at the same
time. Vector Diagrams, Harmonic Analysis, Input Waveforms and
Tables with the numerical values of Voltage, Current, Phase Shift,
Power, frequency are displayed on different screens.
VT Testing
Voltage transformers can be tested for turn ratio and phase displacement angle with HV voltage probe (for the primary side)
and one of the voltage inputs (for the secondary side)
Simultaneous Accuracy Testing
of the Entire Measurement Circuit
If you don’t measure it, you can’t manage it. Gold Miner is the
first device of its type to test the electricity meter using exact, simultaneous measurements made on all primary and all secondary phases of the circuit. Perform in-service meter testing with a
combined 3-phase load, or a single-phase load. Gold Miner not
only displays the Meter’s accuracy, but also the overall, true accuracy resulting from the CTs + Meter combination for your entire measurement circuit.
Automatic CT Burden
& Ratio Testing
of ALL Phases without Interruption
With the push of a button, CT Burden and Ratio Tests are performed on all phases, without interruption. This is the fastest
and safest way to test. You can view all burden graphs and tables
from any test site directly from memory on the large LCD display.
Demagnetization of an operating current transformer can be
carried out if the secondary circuit resistance is increased stepwise till the core gets into saturation, and thereafter is again
stepwise decreased. The lower the secondary circuit current,
the greater the resistance required for saturation. We ensure for
demagnetization resistances up to 50Ω and power up to 100VA.
Improved Accuracy – 0.04% max
The electronic components used in the three-phase analyzing
standard are with lower temperature and annual drift and show
excellent repeatability of measurement.
User Safety Design
600V CAT IV for a measuring instrument means that it can be
operated on outdoor installations with rated voltage up to 600V,
and that it can support instantaneous overvoltage up to 7kV.
To make our instrument safe for operation under most difficult
conditions, we undertook the following changes in Gold Miner:
- safety fused voltage test leads;
- no metal parts – all sockets and the panel are plastic;
- the analog inputs withstand up to 7kV electrostatic discharge.

The On-Board Consultant
During testing, Gold Miner automatically searches for a variety
of possible conditions on your circuit, which may warrant your
attention. Upon detection, the on-board Consultant explains its
findings, and provides guidance for further investigation so you
may ultimately make money-saving corrections.
Save and View Saved Files
Gold Miner IV stores up to 100 test sites in a non-volatile memory. All these files can be transferred to a PC via USB port or
viewed on the display of the unit. When saving, the operator
need only enter the Location name and the ID Number of the
meter. The date and time are automatically saved.
Testmet Software
Testmet Software uses MySQL Database. Searches with different
criteria may be performed and Test Reports viewed and printed.
The operator is able to customize the heading of the Report and
add additional notes.
