## Choosing the right electrical protection devices for industrial control system

Electrical protection devices are critical for ensuring the safety and reliability of industrial control systems. With so many types of devices available, it can be challenging to know which ones to choose. Here are some factors to consider: What Types of Electrical Faults Can Occur? Different protection devices are designed to detect and mitigate different types of faults. Overcurrent protection devices, such as fuses and circuit breakers, protect against overloads and short circuits. Ground fault protection devices, such as GFCIs, protect against ground faults, which occur when electrical current flows…

## How to calculate Generator Sizing?

Calculation for Generator sizing Procedure The generator sizing is done based on the following conditions. a) Load Calculate from continuous. b) 10 % spare capacity for future loads. A) Calculation of total load: Total connected load as per load summary given below. (Refer to generator sizing-load-summary details ) Continuous Load Total KW  237.22 Total KVAR  0.00 Total KVA 279.08 Minimum KW =237.22 KW Maximum KVA =279.08 B) Calculation for Generator Capacity  Generator Capacity (In KVA) =Maximum Load X 1.1 = 306.99 KVA (Considering 10% spare capacity for future loads) So we select…
