In the industrial setting, safety is always a top priority. Relays and safety systems play a significant part in keeping industries running in a healthy and safe manner.
Protection relays and circuit breakers are the most powerful components in large interconnected power networks. We need enough protection to keep the malfunctioning zone segregated from the rest of the network. When two pieces of protective equipment are deployed in series, they are said to be matched or selected if they share particular characteristics that allow for a specified operating sequence. Relay coordination is a key aspect of protection system design because it ensures quick, precise, and precise relay operation to separate the power system’s problematic portions.
Meaning:
Any electrical design and operation require a thorough understanding of power systems. The typical power system analysis performed for all plants and factories for proper functioning includes a relay coordination study services or relay coordination calculation. Electrical repair and plant operation relies heavily on relay coordination studies. Relay coordination study service are carried out to ensure the system’s safety & to prevent nuisance tripping.
Why is it necessary to do a relay coordination study and analysis?
The goal of the relay coordination study services is to guarantee that the system’s safety functions appropriately and that unwanted tripping is avoided, as safety is a top priority in any organisation, and they rely on protective devices to accomplish so. The reason for annoyance tripping is the modification of protective devices and their parameters during upkeep without sufficient research and analysis.
The goal of relay coordination study services is to define the features, classifications, and setting of overload protective devices so that when devices isolate a defect or overload anyplace in the system, the minimum included all load is interrupted. It is necessary to undertake a coordination study.
- To potentially select protection and utilisation equipment during the early development phase of a new system.
- When the device is upgraded with rated higher equipment when a current infrastructure is upgraded and new workloads are installed.
Approach for doing a relay coordination study Services:
The majority of relay coordination study is done with the use of computers. For the protective relay analysis of power systems, there are numerous computer programmes available. Fault current analysis & circuit time-current characteristics are examples of such programmes. The protective coordination software’s main function is to generate one-line diagrams, calculate relay settings, and draw time-current coordination drawings. The software will include tools for modelling various protective devices and equipment damage curves, as well as storing the data for later use. The device parameters can be retrieved from the collection and used in coordination experiments using the programme.
Advantages of relay coordination study Service :
- According to electrical safety standards and regulations, relay coordination study services are critical for protecting downstream and upstream breakers and preventing circuit breaker problems. This coordination research is necessary in order to reduce power faults in the system & successfully isolate defects in a sequential manner.
- Relay coordination study Services are employed in any distribution network to isolate problems in the protection system quickly, minimizing the damage to a distribution system. The primary purpose of the protective study is to safeguard the electrical system’s upstream protection equipment.
Objectives of the study :
- The selection of settings of all chain protection systems from the load ahead to the power supply is part of a coordination study. A comparison of the operational periods of all the gadgets in response to various degrees of overcurrent is conducted while choosing or setting these protection devices. The goal is to create an electrical power system that is selectively coordinated.
- In a system that requires dependable electrical service, proper application and cooperation of over-current relays as well as other protective devices are critical. Expert engineers have the necessary experience to apply ANSI and NEC criteria to equipment protection properly.
- Reduced breakers, divisional, direction, power, below, out-of-step, and other specific protective relays must all be set in addition to short-circuit relays.
