Modern relays can be difficult and very time consuming to test. We have developed tools to automate the tests and reports on multifunction protection relays to improve commissioning delays.
Collect all your protection relay data from your office and visualise all your data graphically on an oscillograph in seconds. Analyse your tripping sequence for all your generating stations and your switchyards. Collect your data simultaneously with out affecting other connections, all this respecting the NERC/FERC regulations on cyber security.
Collect all your alarms on your SCADA and identify clearly what tripped your disconnect/breaker. Connect with multiple users without compromising speed and data integrity. Centralise your protection data and reduce your maintaining costs.
In order to properly set protective relays, we can perform a fault study of your system. This has the added advantage of storing all your important impedance information in one place.
As an extension of a fault study, an arc flash evaluation can be performed to improve the safety of personnel. This study will suggest the rating of personal protective equipment that should be worn by employees that could inadvertently be exposed to arc flash incident energy. Often, the study results can be combined with the protection study to propose temporary relay settings to be applied while employees work near live equipment to further limit arc flash incident energy.
Specialised in control and protections for electrical utilities and transportation, we have developed rigorous methods and deliver utility grade panels and drawings approved by our electrical engineers. Each panel is individually tested to ensure quality and electrical integrity before shipping.
Have an engineering service at the tip of your finger when you have a support contract with Hemicontrols. When you are executing a routine maintenance and you need some telephone assistance and we will provide your technicians with engineering support for maintenance. Technologists or Engineers can also be mobilised if needed.
We offer quality drafts personnel that will adapt and follow your drawing libraries and symbols. Take advantage of our experienced personnel to help you in your drafting. Our drafting personnel is experienced in drawing electrical schematics and logics for engineers allowing them to perform and respond with minimum details.Hemi Controls has extensive knowledge and experience writing and testing efficient and easy to understand PLC programs for your systems. Programs are not proprietary, they are yours to maintain and modify has your system grows.
The PLC can be programmed using any of the standard programming languages:
- SFC (Sequential Function Chats)
- FBD (Function Block Diagrams)
- Ladder Diagrams
- Structured Text
- Instruction List
Your SCADA application will be designed and developed to enable your operators to have full control of the system and at the same time to be simple enough that your maintenance personnel will not need to go through extensive training to understand and maintain the SCADA program. SCADA can be designed according to your needs, will it can be a simple operator interface running on a PC or a more extended system using redundant servers and clients machines including safety, historical data and trending features .
Gateway substation used in our projects bridge the gap between substation equipment, devices and control centers. They are the basis of an integrated, automated substation solution. Hemi Controls configures gateway to:
- Perform Protocol conversion
- Communication between devices and system components
- Integrate substation devices and control centers
- Integrate proprietary or standard device protocols
- Meet Cyber Security requirements, such as NERC CIP.
Hemi Controls offers a great range of services responding to various control and power applications such as switching transient studies, ARC studies, commissioning, Power engineering, control engineering, drawings, various brands for PLC programming (Allen Bradley, Modicon, G.E.…), Generator protection, line protection, transformer protection, industrial network design, protocol conversion, panels, SCADA and completely integrated turnkey solutions.
Across North America Hemi Controls has built long term business relationships to maintain a constant growth. The products developed and delivered contributed to the business growth and long term business relations with several clients.
All our projects includes documentation manuals written by the project engineers and technologists who worked on the project. The information provided to you is then precise and relevant.
Your personnel also receives a training on the system. The training is prepared to accomodate your personnnel tasks (Operators, Maintenances, Technologists and Engineers Staff) The training can take place at your facilities and/or in our training room.
