Innovations in robotics and evolving safety standards examined in new white paper Major advances in microprocessor and artificial-intelligence techniques, along with innovations in automation and control systems, are ushering in a new age of robotics, in which once-futuristic visions are becoming realities. Despite these breakthrough applications – in areas ranging from manufacturing to medicine – robots carry risk. Without the proper precautions in place, a robot experiencing a fault or failure might cause serious injuries to people and damage to capital equipment in or around the work cell.

Benchmarking the performance in electrical space Setting clear performance expectations up-front and holding employees accountable for their actions, electrical contractors yield a more productive and satisfied workforce
Understanding the benefits & risks of isolated ground wiring The length of the IG circuit from the solidly grounded AC source to its outlet end affects the impedance of its path from one end to the other. This, in turn, affects the amount of electrical noise current (as opposed to electrical noise voltage) the IG path can propagate along its route.
Reducing harmonic distortion in industrial environments The distortion of individual nonlinear loads will vary somewhat, depending on several factors such as source impedance, load current, and system voltage distortion. The waveform measured at the common power source will result from the combination of all of the individual loads.
Designing the ground-fault protection strategy The effect of a gen-set and its transfer switch on the operation of GFP equipment requires close attention, mainly because of the multiple neutral-to-ground connections
Making the accurate PQ measurements The presence of harmonic currents will distort sinusoidal waveforms. In fact, the main culprit of power distribution harmonic problems is voltage distortion. As harmonic currents pass through a power distribution system’s total impedance, they create voltage distortion.
Calculating the short circuit A circuit breaker can’t interrupt a circuit at the instant of inception of a short. Instead, due to the relay time delay and breaker contact parting time, it will interrupt the current after a period of five to eight cycles, by which time the DC component will have decayed to nearly zero and the fault will be virtually symmetrical.
Knowing the basics of wye transformer calculations The ratio of a transformer is the relationship between the number of primary winding turns to the number of secondary winding turns and thus a comparison between the primary phase voltage and the secondary phase voltage.
Commercial load calculations The voltage to use for your calculations depends on the system design voltage. Thus when you calculate branch-circuit, feeder, and service loads, you must use a nominal system voltage of 120V, 120/240V, 208Y/120V, 240V, 347V, 480Y/277V, 480V, 600Y/347V, or 600V unless otherwise specified (220.2)

Voltage fluctuations: Analysing the causes & remedies The phenomenon of flickering in light sources has been an issue since the beginning of power distribution systems. However, with the increase in number of customers and installed power, the problem of flicker has grown rapidly..
Measuring motor and transformer inrush currents Evaluating these concerns requires measurement equipment that can capture the waveforms over the full duration of an event, such as the starting of a motor or the energizing of a transformer, which can take a number of seconds. This measurement equipment can include expert systems that look through significant amounts of monitoring data and identify particular events and conditions.
Managing the harmonics in AC drive applications The AC-to-DC conversion is what causes the harmonics. Current flows only during part of the cycle, creating the odd-looking current waveform shown in Fig. 3. It’s this distorted current that creates the voltage distortion. This is why a drive is considered a nonlinear load.
Feigning the transients in power systems Simulating electromagnetic, electromechanical, and control system transients, these software tools allow you to insert various components that are a part of the power system under evaluation, and then test the entire power system to a range of transient conditions. The AC-to-DC conversion is what causes the harmonics.

Vital factors in applying power conditioning equipment The widespread presence of these variations in today’s electrical power supply requires you to pay special attention to power quality. You can interpret the resulting power failure problems as the difference between the quality of power supplied to sensitive electronic equipment and the quality of the power it requires to operate reliably.
Energy storage technologies : The new mantra A transportable LA system with carefully integrated power electronics has been developed with partial funding from the DOE. The system allows high-tech customers to avoid the disastrous effects of micro outages and voltage sags with a payback of one to two years.
Industrial UPS protection : Achieving the cost effeciency Recently the valve-regulated lead acid (VRLA) battery is commonly used at all UPS power levels. It’s also the predominant battery used in manufacturing operations with a UPS system because it costs much less and requires much less space than conventional vented lead acid batteries (wet cells).
Minimising the electrical hazards at workplace Recently the valve-regulated lead acid (VRLA) battery is commonly used at all UPS power levels. It’s also the predominant battery used in manufacturing operations with a UPS system because it costs much less and requires much less space than conventional vented lead acid batteries (wet cells).
Choosing the lubrication for electrical systems A lubricant also can serve as a coolant, prevent corrosion and block the entry of contaminants. Satisfactory grease also will resist breaking down by separating into its constituent components, be reasonably stable and not change its nature significantly within the temperature range for which it was designed.
Thermal imaging: Vital tool for electrical distribution system A thermal imager probably can provide the fastest answer to this question. Scan the electrical components, look for abnormal temperatures and zero in. The follow-up question, “What happened?” is answered by a combination of technician and electrician expertise, and various electrical tests and measurements.
Controlling voltage transients for optimum energy efficiency Then and now. In the past, difficulties in pinpointing and troubleshooting electrical problems often led to disrupted or failed industrial equipment. This was especially true with transient voltage spikes, due to their short duration and often unpredictable pattern of occurrence.
Interpreting and analyzing power quality measurements Power qulity has become a key concern for utility, facility, and consulting engineers because end-use equipment is now more sensitive to disturbances arising both from the utility power supply and within a customer’s power distribution system. Also, this equipment is more interconnected in networks and industrial processes, meaning the effects of a problem with any one piece of equipment are much more severe.
Maintaining the variable frequency drives & motors Periodically scan operational motors with a noncontact temperature device and look for abnormal hotspots. Having a baseline temperature to refer to helps evaluate temperature readings.
Executing the electrical project : Adopting the right approach Keeping the project on the schedule and hitting each and every milestone along the way is the hard part. Keeping your job on track is not that difficult; however, you must make certain weekly and daily processes second nature in order to consistently achieve success.
Increasing the motor life with right calculations To determine the minimum ampacity of the motor supply conductors, you obviously need to know how much current the motor draws. But there are different types of current in motor applications which do you use full-load current (FLC) or full-load amperes (FLA) for your motor calculations
