Diesel generator sets

Peterson Power Systems provides diesel generator sets for any application or specification. Our diesel generator sets inventory is built according to world-class standards and complies with global emissions regulations. You can expect high efficiency and low fuel consumption from the range of options we have for your power needs.

Prime, Continuous or Standby Power

Selecting the right diesel generator set for your application depends on your power needs. Prime power generation provides the main source of power and is designed to operate for extended periods of time at variable load. Standby power generators are often used in emergency situations and are installed to protect businesses from the consequences of loss of primary electric power supply. Continuous prime power is very similar to prime power generation but has a base load rating; these generators supply power continuously for a constant load and are not equipped to handle variable loads or overload conditions.

No matter what power solution you need, with Peterson Power Systems you can expect reliable, clean, and efficient power that is manufactured, designed and engineered for optimal performance.

SpecSizer: Load type evaluation tool

SpecSizer is a set sizing software tool that provides you the ability to evaluate load types such as air conditioners, elevators, ultraviolet lights, single-phase NEMA and single-phase IEC motors. This tool uses different factors, such as site conditions, load characteristics, and required performance to provide you with accurate and timely technical data. This tool can help you to choose and specify a properly sized generator that meets your power needs.

Switchgear

Switchgear is the apparatus used to switch, control and protect electrical circuits and equipment. The most common use of switchgear is to de-energize equipment and clear faults downstream. Switchgear is also used for isolation of circuits from power supplies, and to enhance system availability by allowing more than one source to feed a load.

A switchgear has two types of components:

  • Switching and protecting devices, switches, fuses, isolators, circuit breakers and lighting arrestors. These components conduct or interrupt the flow of electrical power.
  • Control systems: control panels, current or potential transformers, protective relays and associated circuity. These components control and protect the power conducting components.

Switchgear standards

Ratings, design, specifications and details of switchgear are governed by a multitude of standards. In North America, IEEE (Institute of Electrical and Electronics Engineers) and ANSI (American National Standards Institute) standards are generally used.

Peterson Power Systems offers a variety of solutions to manage your power system

Peterson Power Systems offers different switchgear products to support a wide range of applications. We can also provide you with a custom-designed system that will meet your business’s or project’s specific needs. Our switchgear are engineered to manage your power system and are able to combine all monitoring and control elements for generator sets in a single-source set.

Peterson Power Systems switchgear are used for monitoring and controlling standby or load management and multi-unit utility paralleling installations in on-site or off-site setting. We also offer Automatic Transfer Switches (ATS) that control your continuous power source and provide your projects with continued safety and reliability.

Peterson Power Switchgear projects

Comcast Denver - EMCP4.4 Master Control Panel

  • The product provides a single master location from which an operator can view status and control the generators
  • Three 2000kW gensets paralleled to a common bus with electrically operated main breakers
  • EMCP4.4 control panels and EMCP 4.4 MCP for remote location monitoring and control

Automatic Transfer Switches

An automatic transfer switches (ATS) is an integral part of a generator set: it transfers power from one source, the utility, to another, the generator. An ATS triggers when it senses that one of the sources has lost or gained power. An ATS is often installed in conjunction with one or more backup generators to make sure that the generator(s) provide electrical power if the utility source fails. Today every standby generator set that is sold requires at least one ATS, and some cases, multiple units.

More about transfer switches, types and operation of a transfer switch.

Peterson Power Systems offers a broad range of transfer switch products that are positioned to support any type of emergency power application from simple, single-ATS installations to highly complex, multi-ATS/generator switchgear systems. Available in sizes ranging from 40 through 4000A, there is a Cat switch to suit every project's needs.

Overall ATS Features Include:

  • Open & Closed Transition
  • Delayed Transition
  • Bypass Isolation
  • 40 through 4000A
  • Mechanically-held Contactor
  • 50/60 Hz 600 V Class

Maintenance for ATS Products

Good maintenance programs involve all components of a generator, including the ATS. There are several reasons for regular maintenance. In some industries, it is mandatory to perform, at the minimum, a weekly load test. This basic test makes sure the ATS is capable of sending a start signal to the generator and transferring the building load onto the generator for a period of time set by the user. This simple operation ensures the basic functionality of the ATS and generator. However, it does not address other critical operations during the life of the switch.

Peterson Power has resources to offer you maintenance and service for your ATS products: our company has a team of highly qualified, factory-trained, power-focused technicians available to support your project.

Early Detection of Problems – Maintenance contract

A preventive maintenance contract can help identify problems before a failure occurs. Consider, for example, power cables, contactor assemblies and interconnected wires. During a genset’s initial installation, start-up, and commissioning, particular attention is given to these components’ integrity. However, after a period of time, these components can deteriorate, vibrate loose, or become contaminated. Without regular maintenance, failure could occur, causing extensive damage to the ATS, generator, or downstream devices. This type of failure (and resulting costs) can be prevented if the switch is under a maintenance contract.

A maintenance contract should include, but not be limited to, the factory recommendations for testing and maintenance. These basic services will ensure high reliability and prolong the life of your ATS.

At Peterson we offer service contracts, which are critical to your power installation’s success. Our service contracts guarantee full local product support, and access to services infrastructure and parts inventory. Our goal is to provide you with options and guarantee quality project maintenance with 24 /7 support.
