Indian Locomotive Class WAG-7
The Indian locomotive class WAG-7 is a class of 25 kV AC electric locomotives that was developed in 1990 by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), alternating current (A), goods traffic (G) engine, 7th generation (7). They entered service in 1992. A total of 1970 WAG-7 were built at CLW and BHEL between 1990 and 2015, which made them the most numerous class of mainline electric locomotive till its successor the WAG-9.

Tap Changer
A tap changer is a mechanism in transformers which allows for variable turn ratios to be selected in distinct steps. This is done by connecting to a number of access points known as taps along either the primary or secondary winding. Tap changers exist in two primary types, no-load tap changers (NLTC), which must be de-energized before the turn ratio is adjusted, and on-load tap changers (OLTC), which may adjust their turn ratio during operation. The tap selection on any tap changer may be made via an automatic system, as is often the case for OLTC, or a manual tap changer, which is more common for NLTC. Automatic tap changers can be placed on a lower or higher voltage winding, but for high-power generation and transmission applications, automatic tap changers are often placed on the higher voltage (lower current) transformer winding for easy access and to minimize the current load during operation. Tap changing No-load tap changer No-load tap changer (NLTC), also known as Off-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Locomotive Class WAG-8
The Indian locomotive class WAG-8 is a class of 25 kV AC electric locomotives that was developed in the early 1990s by Bharat Heavy Electricals Limited (BHEL) for Indian Railways. The model name stands for broad gauge (W), AC current (A), freight/goods traffic (G), eighth-generation (8). Only two units of this class were built, both prototypes. This class provided the basic design for a number of other locomotives like the WCAM-2, the WCAM-3 and the WCAG-1. History The history of WAG-8 begins in the early 1990s with the aim of addressing the shortcomings of the previous WAG-5 class and remove steam locomotives from IR by a target date of 1990. The WAG-5 though were greatly successes, had become underpowered to meet the growing demands of the Indian Railways. So in the early 1990s BHEL decided to look for a successor to the WAG-5 class. The required specification was of a 5000 horsepower locomotive. Initially, the Indian railways invited tenders to build locomotives to t ...
