Power Studies

Load Studies

Load studies are extremely useful to energy consumers for safety, operational and financial reasons. These include determining if an existing power distribution system can cope with new loads, verifying cable and system capacity, balancing load distribution over phases, keeping track of power factor and to quantify energy consumption before and after improvements.

When a building owner wants to add new loads to an existing service or set of feeders, the first thing you have to is determine is whether the existing system will support the new loads.

To answer this question you have to ask another one: What is the highest load the system carries now? Often, local electrical authorities will need to know these answers before they issue permits. You will also need a comprehensive understanding of the current load to evaluate the new system, once installed.

To determine the existing equipment’s loading, you will need to measure the existing loads. Record the demand over a 30-day period and find the maximum demand.

Using the latest state-of-art equipment we are able to carry out detailed load studies over a period of time and provide you with a detailed report with our findings.

Avoid financial Penalties

Power factor is one important measurement collected in a load study. Electrical utilities often impose fines if the power factor of a site drops below a contractually agreed value. Keeping track of power factor, and implementing appropriate power factor correction can avoid financial penalties. A load study is therefore also a powerful aid for ensuring that an energy consumer is being charged for what it actually uses.

Power quality Troubleshooting

Voltage sags, tripping breakers, overheated electrical panels and excessive voltage levels are all indications of possible trouble in an electrical distribution system. It is helpful to understand that these symptoms are telling us something is wrong with the power system. But where do you begin the search to isolate the exact cause of these power quality problems? Just like cars have a single connection point to monitor vital functions, the electrical system has a similar connection point: the electrical service panel. As a common point for branch circuit distribution, the service panel is also a convenient place to take the pulse of your electrical system. A number of problems can be located right in the service panel itself. For problems elsewhere in the system, measurements at the service panel can tell you where to look next. Some problems can be caught by a quick visual inspection, while others require that measurements be taken.
