Case Study: Power Quality Problems Can be Costly; Lost Revenue, Interrupted Operations
www.dranetz.com
Despite their differences, continuous-process industries share underlying characteristics: they maintain continuous operations in facilities that represent substantial start-up costs and time, yet can be interrupted or disrupted by seemingly minor fluctuations in power quality. If the product stream is disrupted, lost productivity and lost product can create a large financial burden. For example, a voltage sag in a paper mill can waste a whole day of production and inflict a $250,000 loss, while a 5-cycle interruption at a glass manufacturing facility can cost a minimum of $200,000. It is estimated that three percent of every sales dollar in the US is spent on power quality problems. Seventy five percent of all power quality problems occur inside customer facilities, requiring power engineers and electricians to diagnose and solve these problems themselves.
Unfortunately, these percentages will only increase as loads become more sensitive to power quality events and the power utilities become more decentralized. For facility managers and engineers, understanding and managing power system infrastructure is essential to ensuring reliability of production, optimizing equipment performance, and controlling escalating energy costs. Power monitoring can potentially detect deterioration in power quality before problems arise.
The Dranetz Encore Series Power Monitoring system enables users to proactively monitor their power system, potentially identifying and correcting problems before they occur. Additionally, with the proprietary AnswerModules, this system aids in troubleshooting by quickly identifying the direction, or source, of the problems before and after they occur.

When is Ground not a Ground?
By Richard P. Bingham, Dranetz
www.dranetz.com
www.dranetz.com
Grounding is a term that has many different facets, depending on the application. Some of the
reasons for grounding systems and equipment are to: limit the voltage imposed by lightning, line
surges, or unintentional contact with higher voltages; stabilize the voltage to earth under normal
operation; establish an effective path for fault current that is capable of safely carrying the
maximum fault current and with sufficiently low impedance to facilitate the operation of
overcurrent devices under fault conditions. In addition, the most important application is to
increase the protection people and equipment from shock and/or damage.
In the power quality field, grounding plays an important part in the proper operation of "sensitive" equipment. "Of all the power and grounding problems affecting electronic load equipment, almost 90% are caused by electrical power and grounding conditions inside the facility in which the equipment is used....More importantly, almost 75% of the power quality problems inside the facility relate to grounding, which makes it the single most important factor from a facility standpoint, in having reliable equipment operation." [Warren Lewis, "Quality Grounding and Power Quality: Having Your Cake and Eating It, Too", EC&M Power Quality Advisor, February 1998]
More numerous than the reasons for grounding are the terms related to grounding. The Grounding Subcommittee of NFPA70B Electrical Equipment Maintenance Committee has compiled over fifty related definitions. Article 250 of the National Electric Code is a good source for many of the definitions, though one must remember that the primary purpose of the NEC is to protect life and property, and not necessarily ensure that equipment will run properly in a facility. This does not imply that any of the requirements should be compromised for the sake of improved performance, but rather additional efforts may be required.
A grounding system has several key components: the connection to earth (often the grounding electrodes); the grounding conductor (typically called the green wire); the bonding jumper that connects the grounding conductor to the grounded conductor (often referred to as the neutral); and, the connection of the equipment connected to the grounding system. A few of the definitions from the NEC are listed below, to ensure that we are all speaking the same language.
Bonding Jumper - A reliable conductor to ensure the required electrical conductivity between metal parts required to be electrically connected.
Grounding Conductor - A conductor used to connect equipment or the grounded circuit of a wiring system to a grounding electrode or electrodes.
Grounding Conductor, Equipment - The conductor used to connect the noncurrent-carrying metal parts of equipment, raceways, and other enclosures to the system grounded conductor, the grounding electrode conductor, or both, at the service equipment or at the source of a separately derived system.
Grounded Conductor - A system or circuit conductor that is intentionally grounded.
Grounding Electrode Conductor - The conductor used to connect the grounding electrode to the equipment grounding conductor, to the grounded conductor, or to both, of the circuit at the service equipment or at the source of a separately derived system.
Grounding Electrode - A grounding electrode is a conductive body deliberately inserted into earth to make to electrical connection to earth.
The grounding system operates under the same rules as the normal current carrying conductors.

Proactive Energy and Demand Monitoring
www.dranetz.com
In today’s world where facility staff managers and team members are wearing multiple hats, having information at your finger tips is a requirement. Even more so, having valuable information that can be acted up is even more critical. A typical facility can save from 10% to as much as 40% annually on energy costs by implementing a comprehensive energy action plan. And, while each facility will require an organized approach to recognize those savings, facilities first need to understand their power consumption, location of major loads, electric demand usage patterns, and associated costs.
In today’s world where facility staff managers and team members are wearing multiple hats, having information at your finger tips is a requirement.

A typical facility can save from 10% to as much as 40% annually on energy costs by implementing a comprehensive energy action plan. And, while each facility will require an organized approach to recognize those savings, facilities first need to understand their power consumption, location of major loads, electric demand usage patterns, and associated costs.
Many companies today are developing energy management plans and actions requirements to address and limit their growing costs of energy. Part of these plans is the act of reducing energy consumption when peak demand levels are being reached or when electric rates are at their peaks. In order to do this facility operators need to have intelligent metering in place which is capable of recording and forecasting electrical usage in a real-time basis. Additionally, the responsible staff needs to know what these values are at any point in time and know what action to take. However, having someone sit at a computer screen or in front of meter panels to watch the energy levels increase and decrease is not a productive use of time or money. This is why it’s critical to have an intelligent system monitoring the various parts of the facility.
Utilizing the Encore Series ES230 DataNode’s along with the Encore Series Software, a facility can easily view their instantaneous, historic and predicted demand, energy consumption (as well as many other parameters), and associated costs at each point whenever they need. Additionally, the Dranetz Encore Series Software has built-in intelligence which proactively monitors any or all points identified, and has the ability to create alarm points based on an the plans requirements. This system proactively monitors present and predicted demand and usage levels, when the programmed threshold (limit) is exceeded, the Encore Series Software will send out alarm notifications to as many individuals as needed. These notifications can be in the form of email, pager, or the ever popular text message to a cell phone.
The Encore Series Software is a web enabled application that does not require the installation of any software on a local users computer. The system can be accessed from any web-enabled browser by multiple people simultaneously, and performs a variety of operations, including; data collection, data analysis, reporting, alarming, and remote setup of the equipment. With the Modbus driver installed the software can easily read data from any previously installed instrument that supports the Modbus protocol. Additionally, the software allows for easy expansion, including the addition of Power Quality instruments for more detailed analysis of power anomalies.
