Magtrol Model 6530 Three-Phase Power Analyzer
6510e/6530
analog output option
external shunts/sensors
The Analog Output is a plug-in module designed specifically
for use with the 6510e Single-Phase Power Analyzer and 6530
Three-Phase Power Analyzer.It provides up to 12 channels (3
for the 6510e, 12 for the 6530) of analog output corresponding
to volts, amps and watts. Each output is capable of, and
calibrated to, ± 10 volts.With the analog output option, the
user may apply a scale factor to all outputs.Amps scaling is
applied to all amp channels, volts scaling is applied to all volt
channels and watts scaling is applied to all watt channels.
If currents continuously reach above 20 amps, an external
sensor must be used. Magtrol offers three different types of
external shunts for use with Magtrol models 6510e or 6530
High-Speed Power Analyzers.
Other features include:
•

3.2Protecting Your 6530
Before the 6530 is used for power measurement, guidelines regarding transient overloads, current
overload, surge protection and circuit breakers must be followed.
3.2.1
Transient Overloads
Connect an appropriate transient suppressor in parallel with all inductive loads. Consult the suppressor
vendor’s application literature for proper selection and sizing.
Caution:
Damage to the 6530 can result from excessive voltage transients
generated by unsuppressed inductive loads. This damage is not
within the scope of the normal instrument service and is not
covered by the Magtrol Warranty.
3.2.2
Current Overload
There are no fuses in the 6530 measuring circuits. Therefore, excessive current passed through the
amps terminals will cause excessive internal heating and possible unit damage.
Caution:
This overload abuse is not covered by the Magtrol Warranty.
Know your load conditions and double check all connections. If an overload should occur,
immediately remove all power and locate and correct the problem before re-energizing your circuit.
If a circuit breaker is installed, it must be installed on the load side of the 6530 (downstream). This
will keep the low impedance of the input line connected to the 6530 for surge suppression. If the
line side must also contain a breaker, it should be delayed in operation to open after the load side
breaker has opened.
3.2.3
Surge Protection
Use Metal Oxide Varistors (MOV) or other equivalent transient suppressors connected between lines
at the load (across the load). These suppressors are an absolute necessity when inductive loads are
used. In three-phase systems, each load must have a suppressor.

Circuit Breakers
With the circuits described in Section 3.3.1.1 - Hardware Connections, use the 6530 remote voltage
sense by measuring the voltage at the load. This increases measurement accuracy by eliminating
line voltage drop from the power measurement. For safety, an overload circuit breaker removes
all load voltage during an over-current condition. The voltage sense lines are connected at the line
side of the circuit breaker to help prevent inductive transients from entering the 6530 as the circuit
breaker opens. Make sure that connections from the circuit breaker to the load are heavy conductors
and short as possible.
Caution:
If a circuit breaker is used in the input line to the 6530, a circuit
should be used that prevents the breaker from opening until
after the load side breaker has opened. Otherwise, potentially
damaging inductive transients can be applied to the 6530. Damage
caused by these transients are outside the scope of the Magtrol
Warranty.

Testing Instrumentation Setup
Before the 6530 can be utilized, it must be configured and connected to the devices intended for
power measurement.
3.3.1
Wiring Mode
The 6530 has the ability to support a combination of up to 3 phases, therefore, there are a number
of different ways in which the unit can be wired.
3.3.1.1
Hardware Connections
SETUP
The wiring mode selections include:
• 1-Phase, 2-Wire
• 1-Phase, 3-Wire
• 3-Phase, 3-Wire
• 3-Phase, 4-Wire
• 3-Volt, 3-Amp
The following pages provide more detail on the power measurement, as well as wiring connection
diagrams and schematics, of the different wiring modes.
Note:
Active Power is the sum of the instantaneous volts multiplied by
the instantaneous amps inputs.
Apparent Power is the product of volts root mean square and amps
root mean square.
17
Chapter 3 – Installation/Configuration
Magtrol Model 6530 Three-Phase Power Analyzer
1-Phase, 2-Wire
Measures single-phase power.
Can be wired on any input module.
The Power Factor is derived from the following equations:
Amps Σ = Ax, Volts Σ = Vx
Active Power = WØ
Apparent Power = VrmsØ × ArmsØ = VØ AØ
•
Power Factor = WØ / VØ AØ
(Where Ø is the phase of operation)
Most commonly used for single phase AC and DC motor applications.

Active Power = ΣW = W1 + W3
Apparent Power = (Vrms1 × Arms1) + (Vrms3 × Arms3) = V1 A1 + V3 A3
Power Factor = ΣW/( V1 A1 + V3 A3)
The following diagrams show the connections for a 1-Phase, 3-Wire measurement. Notice that

Peak Hold / Inrush Current
Peak hold/inrush current allows the 6530 to store the highest value read in a designated period of
time, the designated period of time being the time span since the last peak hold clear occurred. Values
include amps, watts and volts in any preferred combination. See Section 3.3.7.3 – Peak Hold.
The graph below shows the current draw from a 1/3 horsepower motor during initial startup. At
startup the current inrush peaks at about 14 amps then settles to 4.25 amps. When the unit is in peak
hold/ inrush mode of operation, the front panel current reading displays 14.033 amps. The current
reading indicates the peak inrush current, which is determined by the RMS value.
The operation of the volts and watts peak hold follows the same operation as explained for the
current above.

Measurement Methods
4.4.1
Cycle-by-Cycle Mode
In the cycle-by-cycle mode the power analyzer looks at each complete cycle of the incoming
waveform. The measurements are valid from 20 Hz to 500 Hz. The power analyzer may be
synchronized from any of the phase volts or amps inputs, the line voltage or the back panel external
sync input. If using volts or amps for synchronization, the input must be greater than 10% of the
range setting.
4.4.2
Continuous Mode
In the continuous mode the measurement values are determined from continuously processed and
filtered volts and amps input values. The measurements are valid from DC to 100 kHz and the
output data rate from the process is about 109.24 samples per second. The power analyzer does not
have to be synchronized to the measured waveform and the user may select the filter to be used in
the mean process of the RMS value.

5. Computer Controlled Operation
Using the 6530 with a personal computer (PC) enables the unit to perform at its full capacity.
5.1About the GPIB Interface
Magtrol prefers the GPIB (General Purpose Interface Bus)/IEEE-488 Standard for computer-toinstrument interfacing because:
• The GPIB parallel interface is faster than serial interfaces.
• The GPIB enables testers to access up to 15 instruments on one port. Because typical motor
testing requires that at least five separate parameters be synchronized, a system of easy, fast
access to more than one instrument is essential.
• The GPIB has rigid data formatting and hardware standards. These standards help to ensure
that all functions will work properly when the hardware and software are installed.
Note:
5.1.1
The GPIB interface is not standard on most personal computers. An
interface card and driver software must be installed. An IEEE-488
cable must also be installed between the computer and the 6530.
Magtrol recommends National Instruments Corporation hardware
and software.
Installing the GPIB/IEEE-488 Connector Cable
Caution:

Analog Outputs
An option to the 6530 is an analog output plug-in module that provides 12 channels of analog output
corresponding to volts, amps and watts. Each output is capable of, and calibrated to, ± 10 volts. The
user may apply a scale factor to all outputs by selecting “Analog Outputs” in the USER MENU. See
Section 7.1.4 – Software Configuration. Amps scaling is applied to all amp channels, volts scaling
is applied to all volt channels and watts scaling is applied to all watt channels.
7.1.1
Specifications
Full scale output range:
±10 V max.
Number of channels:
12
Output update rate (all channels) = 200 samples/sec (5 ms)
User selectable analog output scaling values are set from the front panel. Amp, volt and watt scaling
values correspond to units per analog output volts.
(units/output volt) × displayed measurement value = output volts
Examples:
• +15.000 V1 with volts scaling set to 10 V/V
• -100.00 V1 with volts scaling set to 100 V/V
• +5.000 A1 with amps scaling set to 1 A/V =

Warning:
In performing the following procedure,
it is assumed that proper ESD protection procedures will be implemented. The circuitry
involved is very static sensitive. If the analog output board is purchased separately, the board will need to be installed in the 6530
with no other setup required. Installation instructions are as follows.
1. Turn the power OFF.
2. Disconnect the line cord.
3.Open the top cover of the unit by unscrewing the top four screws.
Note:
Care should be taken when removing the top cover because there
is a ground strap attached to it.
4. Disconnect the ground strap from the cover and lay the cover aside.
5. Locate the connector J3 / AUX2.
6.On the back of the 6530 is a cover plate associated with that connector. Remove the cover
plate by removing the two screws.
7. Slip the analog output board through the back of the unit and plug it into J3 / AUX2.
