1 - Introduction ABBREVIATIONS SAFETY PA - Model 5300 Power Analyzer. Securely ground the 5300 PA case by connecting a good earth ground at the ground stud that is located on the rear panel. Use a number 12 AWG wire, or larger. GPIB - IEEE-488 Instrument Bus Standard. LED - front panel indicator light. A, V, W, PF and VA: Amperes, Volts, Watts, Power Factor and Volt Amperes, respectively CONNECTORS The following plugs mate with 5300 PA connectors: MPU - Microprocessor unit.
Chapter 1 - Introduction Magtrol Model 5300 Three Phase Power Analyzer INSTALLATION TRANSIENT OVERLOADS ORIENTATION Connect an appropriate transient suppressor in parallel with all inductive loads. Consult the suppressor vendor's application literature for proper selection and sizing. The 5300 PA must be mounted within ± 20 degrees from horizontal. This ensures proper operation of the mercury shunt bypass relays. ELECTRICAL LOAD Use wire rated for the maximum load current and voltage expected.
2 - Specifications VOLTAGE ISOLATION Three DC and AC Ranges: • 150, 300, and 600 Volts DC and Volts rms. 1500 Vrms break down from input circuit to chassis (ground). Remote Voltage Sensing: • Differential input - 110 dB CMRR. • Maximum of 30 Volts peak, volts low terminal to amps output terminal. CURRENT Three DC and AC Ranges: • 5, 25 and 100 Amps DC and Amps rms. DISPLAY AUTO ZERO When the A and V display indication is less than 0.5 % of range, the displayed value is set to ZERO.
Magtrol Model 5300 Three Phase Power Analyzer Chapter 2 - Specifications DIGITAL • • ACCURACY CERTIFICATION Processing: Integration period = 0.10 second. Display update time = 2 readings per second. IEEE-488 (GPIB): Synchronized = 0.1 sec. per reading Non-synchronized is 0.04 to 0.07 sec per reading. MEASUREMENT ACCURACY Specified test conditions: Ambient temperature of 72° ± 10°F and power factor of 0.1 to 1.0, lead or lag. VOLTAGE - DC + (0.1% of reading + 0.
3 - Connecting the 5300 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 3-phase systems, each load must have a suppressor. See Figure 1 below. Always install a properly rated circuit breaker or fuse between the 5300 analyzer and the load.
Chapter 3 - Connecting the 5300 Magtrol Model 5300 Three Phase Power Analyzer SINGLE PHASE AC OR DC CONNECTIONS See figure 2. NOTE: If a circuit breaker is used in the input line to the 5300 PA, 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 5300 PA. Damage caused by these transients are outside the scope of the MAGTROL WARRANTY.
Magtrol Model 5300 Three Phase Power Analyzer Chapter 3 - Connecting the 5300 3-PHASE 3-WIRE DELTA CONNECTIONS The power dissipated in each phase (PØ) is equal to the product of phase voltage ( Ephase), phase current (Iphase) and cosine of the phase angle θ between the phase voltage and phase current: PØ = Ephase × Iphase × cos θ Each phase power is displayed on the 5300 PA by selecting DISPLAY - Ø1,Ø2 or Ø3 push switch.

4 - Operation Read Section 1 and make sure unit is connected properly (see Section 3) before proceeding. GENERAL 1. Using Sections 1 and 3 as a guide, connect the 5300. Before connecting the power mains, double check all connections (an Ohmmeter is helpful). Verify that the overcurrent circuit breaker is open and connect the power mains. 2. Observing the 5300 front panel indicators, turn the 5300 power switch ON and confirm proper operation - see "Initial Checkout" in Section 1 Introduction. 3.

Magtrol Model 5300 Three Phase Power Analyzer Chapter 4 - Operation AMPERES RANGE ANALOG OUTPUT OPTION Figure 10. This option provides analog output signals for AMPS, VOLTS and WATTS. 5 Current Range Selections 25 100 AUTO These three analog outputs with their common are isolated from the measured circuits at 750 Volts continuous breakdown. The outputs are provided through a standard 5 pin DIN style connector located on the rear panel of the 5300 see figure 11 for connections.
5 - CT/PT Installation External current and potential transformers can be used to extend the measuring ranges of the PA. See Section 4, Figure 6 for a connection diagram. CALIBRATION The 5300 PA compensates all display values for transformer ratios from 0.01 to 255. DIGITAL RANGE The 5300 has special provisions allowing entry of transformer ratios into the non-volatile RAM via the GPIB (IEEE-488) rear panel input.
Chapter 5 - CT/PT Installation CHANGING OR REMOVING CT/PT VALUES To modify a value, simply overwrite the existing value(s). To remove a CT or PT value, output a CT(cl) or PT(cl), only. To remove both, and save the data, switch the rear panel slide switch to "OUT," and toggle the power OFF then ON. If you remove both the CT and PT value correction factors by GPIB instructions, the PA will automatically reset, eliminating the need to cycle power OFF/ON.
6 - GPIB Communication GPIB (IEEE-488) Figure 13. The IEEE-488 or GPIB (General Purpose Interface Bus) provides direct connection and control of the 5300 from any appropriately equipped computer for the purpose of data acquisition and display. MAGTROL factory assistance is available if required. (Address 14 shown) HARDWARE INSTALLATION A GPIB interface requires installation of an interface card in the host computer and driver software resident on the PC's hard disk.

8 - Operating P rinciples Principles The Magtrol 5300 PA uses the three wattmeter method to measure true RMS power. Voltage and current are sensed and amplified in an isolated analog front end, analog to digital converted with 16 bit precision, processed through an 8 bit microprocessor (MPU) and output in BCD form for display on the front panel meters. The PA provides a digital display for each selected phase of rms volts, amps, and watts; average rms volts, amps and watts; and total load power factor (PF).

9 - Calibration GENERAL TEST SETUP Complete calibration of the 5300 PA is beyond the capabilities of most users. Magtrol, Inc. recommends that the 5300 PA be returned to the factory for calibration certifying the instrument to full specifications. The recommended test setup for each phase is shown in Figure 16. NOTE: However, this section includes Calibration Accuracy Verification procedures and steps to make minor trimups of calibration. NOTE: Figure 16.
Magtrol Model 5300 Three Phase Power Analyzer Chapter 9 - Calibration Since the current calibrator output is usually a low impedance with low compliance voltage, the 5300's current measuring shunts are the circuit's major resistance. Let's take a representative example and compute the resulting phase shift: VOLTS CALIBRATION CHECK φ 1 DC: 1. On the 5300 PA, press the 150 volts range pushbutton. Let L = 10 µhenries (total of shunt, wiring, etc.) 2.
Magtrol Model 5300 Three Phase Power Analyzer AMPERES CALIBRATION CHECK DC: 1. On the 5300, press the 5 AMPERES range pushbutton. 2. Set the current calibrator for zero amperes and operate mode. The AMPERES display should read zero + 0.0001% max of range full scale. 3. Set the current calibrator for + 5 Amperes DC. The AMPERES display should read 5.000 Amps. Record the current readings.

Magtrol Model 5300 Three Phase Power Analyzer NOTE: Chapter 9 - Calibration Calibration on the 25 and 100 Amps ranges may have to be done at less than full range scale, depending on your calibration equipment. VOLTS BALANCE 1. Go to the 5300 PA 150 VOLTS range. 2. Set the voltage calibrator for + 150 volts DC output. Note the VOLTS display reading. 3. Reverse the calibrator polarity to -150 volts DC.
