Specific Problem Evaluation

Experts agree that 70% or more of the problems affecting your critical business equipment may be Power Quality (PQ) related. 70% or more! Often, these problems are not easily recognized. They donít necessarily appear to be so called power problems. The lights donít have to go out and you donít always smell smoke! The truth is that PQ related problems may cause symptoms that look like normal hardware problems or software bugs. For the past 20 years, we have been successfully evaluating power quality problems affecting the operation of sensitive equipment in a variety of business sectors including, data processing, telecommunications, manufacturing, and medical. We attribute our success in this difficult area to a thorough understanding of the relationship between power quality and

electronic equipment performance. Our approach is simple and effective: First, we evaluate the problem and determine if it is, in fact, power quality related. If it is, we will provide you with recommendations for an appropriate course of action. If we determine that it is not a PQ related issue, you will have eliminated an important variable in the troubleshooting process.

The Power Quality Healthcheck™

Preventing problems before they can impact your business makes good sense. The Power Quality Health Check is a proactive service designed to do just that. Using a combination of visual inspections, interviews with pertinent employees and specific testing, we will evaluate the current condition of your facilityís operating environment. The objective is to identify weaknesses and deficiencies that can result in premature failures, unscheduled equipment downtime, lost business and unnecessary costs. The evaluation is completely non-intrusive, which means that no equipment downtime is required. The deliverable is a written report documenting all findings, conclusions and specific recommendations to solve any problems found and to enhance existing operating conditions.

Power Monitoring and Data Analyses

While many companies offer power monitoring, not all have the expertise to analyze and interpret the data. APQS provides comprehensive short and long term power monitoring and analyses services for your critical electrical distribution systems. We will provide a written report detailing the monitoring results and specific recommendations based on our analyses and interpretation of the data.

Electronic Equipment Installation Review

Whether you are installing a single piece or an entire floor of critical equipment, the best time to catch problems is prior to going online. APQS offers a comprehensive installation review service designed to ensure that the operating environment has been properly prepared. The review includes visual inspections and specific testing including wiring integrity, sine-wave quality, ground impedance, electrical noise levels, ESD, EMI, RFI and temperature/humidity. Our written report documents all findings, needed corrections and recommendations for enhancements.

New Construction and Renovation Plan Review

Has Power Quality been fully considered in your new construction or renovation plans? Unfortunately, our experience indicates that it has probably not. Power Quality is a highly specialized area and as such is often neglected during the design phase of the project. APQS is prepared to represent your long-term interests and work with your design team to ensure that Power Quality issues are fully considered in the construction design. The objective is to ensure that your new or renovated facility will fully support your critical equipment. The goal is maximum productivity with minimum downtime.

Grounding Electrode System (GES) Evaluation and Testing

The GES is the fundamental component of the facilityís operating environment. Originally designed for electrical safety, the GES has also become the point of zero voltage reference for all electronic equipment in the facility. That is an important task and as such requires a degree of attention and management. APQS offers the following grounding system evaluation and testing services:

  • Four-point fall of potential testing for cellular sites or other critical grounding applications.
  • Soil resistivity testing necessary for the selection of ideal grounding locations in new construction or for the enhancement of an existing grounding system.
  • General facility GES system evaluation.
  • Computer room Signal Reference Ground (SRG) systems evaluation.

The deliverable is a written report detailing all test results, conclusions and specific recommendations as appropriate.
