Reliability engineering deals with an organized approach of time & Cost effective engineering methodologies over a span of product’s lifecycle. Its basic purpose is to develop methods and tools to evaluate and demonstrate Reliability, Maintainability, availability Obsolescence management, Configuration Control Management (CCM) and safety of components, equipment and systems, as well as to support Design and Production engineers in developing these characteristics in the design stage.

Reliability Fundamentals, Basic Purpose, History
The word “Reliability” is a broad term and has been defined differently by various Reliability scholars. Without intricating it further, we will try to understand the Reliability fundamentals in simple words. Reliability may be defined as The probability that an item will perform its intended function for a specified time interval under stated use condition.
What is Supercapacitor (Ultracapacitor) – Characteristics, Working, Types & Applications
This post will discuss about What is Supercapacitor (Ultracapacitor), its characteristics, how it works, types, applications, advantages and disadvantages.
Four Point Starter
Four point starter is connected to a long-shunt compound motor. If we compare it to the generally used 3 point starter, we can easily mark one remarkable difference than its counterpart. In four point starter, the most critical ‘Hold ON coil’ (electromagnet) is placed out of the shunt field circuit. Rather to its place in […]
Series Motor Starter
A face plate/drum type controller is used for starting the series motor. This controller can also be used to control the speed of a series motor as well as to reverse the direction of its rotation. It is commonly known as Series motor starter. As the operator has to monitor the operation of motor continuously, […]
Direct online starter
The most simple and basic type of starter for motors (induction motor) is the Direct Online starter. The Direct on line starter contains an ON/OFF switch and an OLR. Here, OLR stands for overload relay for protection against excessive load current. The selection of switch depends upon the operator’s requirement. Generally, the switch which is […]
Auto Transformer Starter
An Auto transformer starter basically uses an auto-transformer to reduce the voltage applied to a motor during its start. As we know that the starting of big motors which are used for prolonged periods exert large current in the circuit. Due to this, a voltage drop occurs which may damage other electrical equipments which are […]
Star Delta Starter
Star Delta starter comes under the category of starters using reduced voltage method for starting the motor. Just like all other starters, the basic aim to use this starter is to decrease initial high starting current generated by the motor at the starting procedure. It is used for the purpose of limiting the voltage drop […]
Responsibilities of Reliability Engineer
One of the most important responsibilities of Reliability engineer is that he has to work in coordination with other Project engineers so as to ensure reliability, maintainability, availability, parts control, obsolescence management, configuration control etc of new product designs as well as improved designs of old products.
Role of Reliability Engineer
The main role of Reliability Engineer is identification and management of the reliability risks that may have a negative impact on production or post production operation of the product. This can be further split into three main sub categories i.e. Loss identification and reduction, Risk management and Product life cycle support management. Loss Identification and […]
Advantages of Reliability
Why we need to understand and predict Reliability of a product ?? Why to put extra cost and extra efforts in understanding it?? Once the product is manufactured and used, We can come to know about its reliability. Then Why to make it more complex? Why this, Why that?? Well… My friend, Here comes the answer. Though there are many advantages of Reliability as a very crucial product aspect, We are listing few of them.
