Lighting Design is a natural part of the electrical engineering service. Professional Engineering Groups has talented lighting designers/engineers.
Power Distribution is a major emphasis for Professional Engineering Groups. Our project managers have particular knowledge and expertise in providing a diverse range of power to the end loads. Issues such as redundancy, critical emergency, single point failure, life safety, maintenance, etc. are at the fore front
of the design process tailored for each project.
Professional Engineering Groups has designed systems which range from small self-contained units to large UPS systems using both rotary converters and static converters. Professional Engineering has designed unique Ring Bus, 2N and 3N/2 systems with capacities of up to redundant 9000 KVA.
Professional Engineering Groups has participated in proper application of grounding
principles and practices since the 1960's. Our experienced engineers have been involved in many grounding reviews of all types of facilities, including high rise buildings, data facilities,
industrial facilities, telecommunications facilities, and many others. Our engineers helped develop standards for Mission Critical Facilities Grounding Practices. With the advent of using SKM System Analysis, Inc. ground system software, Professional Engineering Groups’ engineers provide effective ground system analysis and designs and apply to modern ground practices in large Data Center buildings, including EMI shielding interfaces.
Professional Engineering Groups offers facility reviews for all types of electrical and related systems. Our approach is to review the systems in a holistic manner to understand how all systems should work together. Detailed reports are provided with specific information describing the issues, recommendations for corrections, budget costs, etc. to assist in obtaining project funding.
Professional Engineering Groups' managers have
experience in the design of and interface to many different types of
automated building alarm and management systems. Our engineers
were actively involved in the development of the standard
specification for Building Management Alarm Systems (BMAS) for
Major Mission Critical Clients.
Our engineers have experience in the full range of systems from single zone protection to high-rise multiplexed systems color graphics and touch screen interface with the capability to interface to BMS for activation of smoke control systems. Many recent designs have also included VESDA (Very Early Smoke Detection Apparatus) for earliest detection of potential problems in critical equipment areas, and interface to agent suppression systems. All designs include interfacing to several different types of environmental, Protection, and Control Systems to perform Critical Life Safety functions.
Security System modification or replacement is common to many projects. Design experience covers all aspects of these systems including: fiber optic cabling, surveillance cameras, P/T/Z controllers, motion & door sensors, card readers, etc., as well as local and remote monitoring. Professional Engineering Groups, Inc. was actively involved in the development of the Standard Specification for Security Systems for Major Mission Critical Clients.
Professional Engineering Groups' managers are familiar with the importance of design using actual calculated short circuit currents. As much as possible, the tripping of circuit breakers in case of fault is coordinated to only trip the breaker closest to the fault. The state-of-the-art SKM System Analysis, Inc. computer programs allow these complicated routines to be done efficiently. Also, the SKM program is used to calculate load studies, voltage drop and voltage flow, network topologies, and ARC Flash.
Professional Engineering Groups offers the service of planning and designing structured cabling systems for commercial and telecommunication buildings, including such systems as CAT5E, CAT6, etc. wiring.
Professional
Engineering Groups has designed various types and sizes of engine
generator systems for standby power supply. The more complex systems consist of 16 MW automatically paralleled engine generator systems. The systems can be designed for Peak Shaving and Utility Curtailment.
Professional Engineering Groups’ engineers have designed large PC, PLC, and proprietary based Interactive graphics power
monitoring and alarm systems, which allow control, status and event
records of operations in complex electrical systems.
Professional Engineering Groups has assisted owners by providing operation and maintenance data for the on-site workforce, including training for
maintenance personnel, documentation for procedures where time and safety are critical and organizing documentation such as drawings, maintenance data, panel schedules, loads, etc.
Professional Engineering Groups
offers a variety of reviews, studies and/or analysis. This investigational segment of our services can include an individual
electrical equipment item, a system, or an entire facility.
Our efforts can focus on a particular incident, equipment failure or potential equipment failure, and address specific issues per the client’s desires. Our approach is to review the issues and systems in a holistic manner, to understand how all entities function separately and together, and provide specific detailed documentation to
address the areas of client concern. Common deliverables provided
are Single Point of Failure Study, Electrical Device Coordination
Study, Short Circuit Study, Grounding System Analysis, Critical Equipment Load Limit Study, Life Safety & Code Violation Study, Failure Analysis, Complete Facility Review, Emergency and Operational Reviews, and more.
Professional Engineering Groups provides
Owners with commissioning services for new and existing systems. The level of commissioning services can range from Test and Acceptance of a specific system, core required commissioning, or full facility commissioning.
