CHAPTER 1: AC POWER MEASUREMENT CHAPTER 1 AC POWER MEASUREMENT The economics of electric power distribution networking dictate several configurations of AC power transmission. The number of phases and voltage levels characterize these configurations. 1.1: Single Phase System A single phase system is a basic two-wire system used in low power distribution applications, such as residential communities or offices. Typically, the voltage is 120V AC.
CHAPTER 1: AC POWER MEASUREMENT Reactive Power (VAR) Apparent Power (VA) Real Power (W) Figure 1.2: Relationship between apparent, real and reactive power Ideal power distribution should have a PF of 1. This condition can be met only if no reactive power loads exist. In real life applications, many loads are inductive loads. Often, corrective capacitors are installed to correct Poor Power Factor (see Section 1.3). 1.
CHAPTER 1: AC POWER MEASUREMENT Voltages between the phases vary depending on loading factors and the quality of distribution transformers. The three-phase system is distributed in different voltage levels: 208V AC, 480V AC, 2400V AC, 4160V AC, 6900V AC, 13800V AC, and so on. Power measurement in a poly phase system is governed by Blondel's Theorem. Blondel’s Theorem states that in a power distribution network which has N conductors, the number of measurement elements required to determine power is N-1.
CHAPTER 1: AC POWER MEASUREMENT 1.4: Waveform and Harmonics Ideal power distribution has sinusoidal waveforms on voltages and currents. In real-life applications, where inverters, computers, and motor controls are used, distorted waveforms are generated. These distortions consist of harmonics of the fundamental frequency.

CHAPTER 3: ELECTRICAL INSTALLATION CHAPTER 3 ELECTRICAL INSTALLATION 3.1: Connecting the Current Circuit Install the wiring for the current at 600V AC insulation as a minimum. The cable connector should be rated for 6 Amps or greater and have a cross-sectional area of 16 AWG minimum. Mount the current transformers (CTs) as close as possible to the meter for best accuracy. The following table illustrates the maximum recommended distances for various CT sizes, assuming the connection is via 16 AWG cable.
CHAPTER 3: ELECTRICAL INSTALLATION OPTION 2: ISOLATING A CT CONNECTION REVERSAL USING VOLTAGE READINGS ! ! Remove potential connections to terminals 6 and 7. Observe the KW reading. It should be positive. If negative, reverse the CT wires on terminals 8 and 9. Connect terminal number 6 potential. If KW decreases to about zero, reverse CT wires on terminals 10 and 11. Connect terminal number 7 potential. If KW is one-third of expected reading, reverse CT wires to terminals 12 and 13. 3.
CHAPTER 3: ELECTRICAL INSTALLATION • The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched on both. The DSP3 input module and the meter base MUST MATCH! • Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration ratios are stored in the meter’s memory, not in the DSP3 input module.

EPM 5300P RELAY OVERVIEW The EPM 5300P offers dry contact relay output capability. The EPM 5200P only offers KYZ pulse outputs and cannot be configured to trip contacts on events. FAIL-SAFE MODE: The EPM 5300P -NL option gives the user an adjustable tripping bandwidth.

CHAPTER 3: ELECTRICAL INSTALLATION Note: Unless otherwise specified, standard KYZ setup for Pulse Output 0 is positive Watt Hour, Pulse Output 1 is negative Watt-Hour, and Pulse Output 2 is VA-hour.

Note: With Option R (available only with the EPM 5200P) the setup for Pulse Output 0 is positive Watt-Hour, Pulse output 1 is positive VAR-hour, and Pulse output 2 is negative VAR-hour.
CHAPTER 4: COMMUNICATION INSTALLATION CHAPTER 4 COMMUNICATION INSTALLATION 4.1: RS-232C (This section applies to the RS-232C or RS-485.) All EPM 5300P and 5200P instruments can be equipped with RS-232C or RS-485 communication. RS-232C communication links a single instrument with a computer or device such as an RTU or PLC. Its capability is up to 100 feet. A standard 9-pin female serial port connector mounts on the instrument for direct connection to a computer with a 9-pin cable.

CHAPTER 4: COMMUNICATION INSTALLATION 4.3: Network of Instruments and Long Distance Communication The RS-485 Transceiver is required for a large network of instruments. • In a two-wire connection, a maximum of 900 instruments can be included in the same network (Figure 4.7) • In a four-wire connection, a maximum of 3600 instruments can be included in the same network (Figure 4.8).
CHAPTER 4: COMMUNICATION INSTALLATION YOU MAY WANT TO USE A MODEM MANAGER RS485-RS232 CONVERTER When speaking to most RS-485 or RS-232C based devices, the remote modem must be programmed for the communication to work. This task is often quite complicated because modems are quirky when talking to remote devices. To make this task easier, EIG has designed a Modem Manager RS-485 to RS-232C converter. This device automatically programs the modem to the proper configuration.
CHAPTER 4: COMMUNICATION INSTALLATION Debugging Communication Problems If you experience NO communication, check these conditions: • • • • Is the Baud Rate set correctly (see Part II: Programming Section)? Is the Meter Address set correctly (see Part II: Programming Section)? Is the correct protocol set? Modbus, DNP 3.0? Set the meter for the appropriate protocol for the internal software.

CHAPTER 5: OVERVIEW CHAPTER 5 OVERVIEW The EPM 5300P displays 17 instantaneous electrical parameters. Values for each parameter are accessed through the keypad on the meter's front panel (see Figure 5.1). The EPM 5200P accesses information in the same manner as the 5300P. The key strokes for each model are identical.

CHAPTER 5: OVERVIEW 5.5: Accessing Max/Min Values Max/min values represent the highest and lowest average demand over a user programmable time period known as the Integration Interval. The readings are calculated using a rolling average technique. Each second, a new reading is used to calculate the max/min; the last reading of the interval is dropped off. The highest max during an averaging period is stored until the user resets the max/min. This is similar to amp demand meters.

CHAPTER 12: GROUPS 4, 5, AND 6 – SET LIMITS AND RELAYS CHAPTER 12 GROUPS 4, 5 AND 6—SET LIMITS AND RELAYS The EPM 5300P -NL offers a comprehensive limit and set point functionality. The user can program above or below limits for every reading, including %THD. When a voltage or current measurement exceeds a particular value, the set limit is triggered and alerts the user. Each limit can trigger two internal Form C dry contact relays for alarm or secondary protection.

CHAPTER 16: ETHERNET OPTION CHAPTER 16 ETHERNET OPTION The EPM5350P, Meter with the Ethernet Option, has all the components of the standard Meter PLUS the capability of connecting to multiple devices over Ethernet. The Meter face is the same as the EPM5300P (except for the model number). 16.1: Ethernet Module The Ethernet connection is made with a small module added to the back of the meter. This small but powerful module has simply an RJ-45 Port and four Status LEDs. ETHERNET 10 BASE T RJ-45 MOD.
CHAPTER 16: ETHERNET OPTION See the Table below for a description of the Status LED functions. LED Description LED Functions 1 Serial Port (Channel) 1 Status Lights solid green to indicate Channel 1 is IDLE. Blinks green to indicate Channel 1 is connected to the network and ACTIVE. 2 Serial Port (Channel) 2 Status Lights solid yellow to indicate Channel 2 is IDLE. Blinks yellow to indicate Channel 2 is connected to the network and ACTIVE.
CHAPTER 16: ETHERNET OPTION 16.3: Default IP Address The Ethernet Interface ships with a default IP address set to 0.0.0.0, whish automatically enables DHCP within the Ethernet Interface. Provided a DHCP server exists on the network, it will supply the Ethernet Interface with an IP address, gateway address and subnet mask when the Ethernet Interface boots up.
CHAPTER 16: ETHERNET OPTION ARP ON WINDOWS In order for the ARP command to work on Windows, the RP table on the PC must have at least one IP address defined other than its own. If the ARP table is empty, the command will return an error message. Type ARP –A at the DOS command prompt to verify that there is at least one entry in the ARP table.
CHAPTER 16: ETHERNET OPTION 16.7: Configuration Parameters After entering Setup Mode (confirm by pressing Enter), you an configure the parameters by entering one of the numbers on the Change Setup Menu, or you can confirm default values by pressing Enter. Be sure to store new configurations when you are finished. The Ethernet Interface will then perform a power reset. Serial Number 5415404 MAC Address 00:20:4A:54:3C:2C Software Version V01.
