Kenny Electric Service, Inc.

Electrical Reliability & Testing

It has been estimated that power related problems cost U.S. companies billions of dollars annually. Companies can save a considerable amount by being proactive in high tech environments. With energy prices at an all time high, facility managers are realizing the necessity of assuring that their building is as energy efficient as possible.

Infrared Thermography

Infrared Thermography is the most recognizable and practical method of electrical and mechanical preventative maintenance. Infrared Thermography is a test method that utilizes a thermal imager to detect, record and display thermal temperature differences and patterns across the surface of an object.

This non-contact, non-destructive test method may be applied to any situation where information about thermal temperatures and profiles will provide helpful data about an object, system or process. When you use Kenny Electric to perform your annual IR scans you will receive top notch service. Your annual IR scan will include:

• Licensed Electricians
• Certified Thermographers
• Adheres to NFPA 70E Safety Standards
• Detailed, easy-to-read report including thermal and digital photographs
• Cost proposal to make any recommended repairs

Preventive Maintenance

We will do a free site evaluation to outline industry standards and recommendations. Switchgear preventative maintenance is recommended every 3-5 years. The preventative maintenance program includes:

• Cleaning interior switchboards
• Torque and tightening all bus bars and mechanical connections
• Testing and calibrating ground fault breakers and sensors
• Primary and secondary injection testing
• Lubrication of interior moving parts

Power Quality

True power quality is only achieved through careful planning and a thorough understanding of the overall facility electrical system. There are a number of factors that contribute to the overall health and reliability of an electrical system.

Surge Protection

It is important that a multilevel-networked surge protection system be installed in every facility. In a typical situation, a surge protection device would be installed where the incoming utility lines enter the main switchgear and on each power panel throughout the building. Surge protection will provide general protection from internal utility and internal facility surges, but will not protect from a direct lightning strike. This is achieved through a lightning protection system.

Grounding

An important aspect of maintaining power quality within a facility is proper grounding. Electric panels should have dedicated grounds that originate from the main buildings ground point. The neutral should be grounded only at the transformer derived ground or the main ground point.

Harmonics

Facilities need to be aware of the possibility of Harmonic Distortion. Harmonic distortion occurs when portions of the electrical load in the facility are electronic power supplies (i.e. CPU Power Supplies, Electronic Ballasts, VFD’s, and Motors). Harmonic currents cause extra heating that could overload the electrical system components such as transformers, capacitors, motors or generators. Facility generated harmonic currents flow through the system and causes the voltage to become distorted. Voltage distortion will lead to malfunctions in equipment and increased operating costs.
