3.2 PROTECTING 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.

3.2.4 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.

3.3 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

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.

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.

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.

5.1 ABOUT THE GPIB INTERFACE

Magtrol prefers the GPIB (General Purpose Interface Bus)/IEEE-488 Standard for computer-to-instrument interfacing because:

• TheGPIBparallelinterfaceisfasterthanserialinterfaces.

• TheGPIBenablestesterstoaccessupto15instrumentsononeport.Becausetypicalmotortesting requires that at least five separate parameters be synchronized, a system of easy, fast access to more than one instrument is essential.

• TheGPIBhasrigiddataformattingandhardwarestandards.Thesestandardshelptoensurethat all functions will work properly when the hardware and software are installed.

Note: 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.

5.1.1 inStaLLing the gPiB/ieee-488 ConneCtor CaBLe

Caution: make sure both the Computer anD 6530 are turneD off before installing the gpib ConneCtor Cable.

1. Connect one end of a high-quality, double-shielded cable to the 6530 GPIB connector.

2. Connect the other end to the GPIB interface in your PC.
