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

Asingle 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. For higher power requirements,

such as small commercial facilities, the typical power configuration is two lines of 120V AC opposite in

phase (see Figure 1.1 B, below).

This system produces 120 volts from line to neutral for lighting and small appliance use. The line-to-line

voltage is 240V AC, used for higher loads such as water heaters, electric dryers, ranges and machinery.

The power (W) in a single phase system is:

cos•I•E=W

E= potential, I= current, and cosΘ= phase difference between the potential and the current.

Power in a 120/240V AC system is: )cos•I•(E+)cos•I•(E=W 2Line2Line1Line1Line Θ

Phase differential between the potential and the current results from a non-resistive load, either reactive

or capacitive.

Reactive power (VAR): The additional power consumed that does not produce any work but must be

delivered to the load:

⋅⋅ insIE=VAR . This is a measure of the inefficiency of the electrical system.

Apparent power (VA): The total power delivered to the load, and the vector sum of real power 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).

1.2: Three-Phase System

Athree-phase system delivers higher levels of power for industrial and commercial applications; the

three phases correspond to three potential lines. A 120° phase shift exists between the three potential

lines.

A typical configuration has either a Delta connection or a Wye connection (see Figure 1.3, below).

In a three-phase system, the voltage levels between the phases and the neutral are uniform and defined

by:

2) Wye

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. A typical configuration of poly phase system has either a Delta

connection or a Wye connection (see Figure 1.4, below).

1.3: Consumption, Demand and Poor Power Factor

CONSUMPTION: TW=WH ×W= instantaneous power T= time in hours

The total electric energy usage over a time period is the consumption of WH.

Typically, the unit in which consumption is specified is the kilowatt-hour (KWH): one thousand watts

consumed over one hour. Utilities use the WH equation to determine the overall consumption in a billing

period.

DEMAND: Average energy consumed over a specified time interval. The interval is determined by the

utility, typically 15 or 30 minutes. The utility measures the maximum demand over a billing period.

This measurement exhibits a deviation from average consumption causing the utility to provide

generating capacity to satisfy a high maximum consumption demand. The highest average demand is

retained in the metering system until the demand level is reset.

POOR POWER FACTOR: Results in reactive power consumption. Transferring reactive power over a

distribution network causes energy loss. To force consumers to correct their Power Factor, utilities

monitor reactive power consumption and penalize the user for Poor Power Factor.

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.

HARMONIC DISTORTION: A destructive force in power distribution systems. It creates safety problems,

shortens the life span of distribution transformers, and interferes with the operation of electronic devices.

The Futura+ monitors the harmonic distortion to the 31st harmonic. A waveform capture of distorted

waveform is also available.
