CSS and PSS
Why T Power?
A compact substation is a ready-to-install product and saves on space, time and cost of acomplete project. CSS is a type tested and arc tested assembly comprising an enclosure containing mediumvoltage (MV) switchgear, distribution transformers, low voltage (LV) switchboards, connectionsand auxiliary equipment to supply low voltage energy from medium voltage systems. Thesesubstations are typically installed in locations accessible to the public and ensure protection forall people according to specified service conditions. CSS is used for energy transformation insecondary distribution network from MV to LV or LV to MV:
All CSS components shall be type and routine tested per their relevant product standards.
* Reduction in installation space, cost & time Type tested per latest IEC standard 62271-202
* High level of safety for personnel & equipment due to the highest degree of Internal Arc Classification.
* Wide range of ratings & capacities as well as layouts in steel, concrete and innovative GRP housing.
* Global leader with huge installed base, global service coverage and high level of engineering capabilities.

Advantages
- * Reduced electrical losses as USS can be installed near load centers.
- * Total economic in cost.
- * Higher degree of safety and operational reliability is achieved by HT and LT switchgears and protective relays to avoid overloading.
- * Reduction in logistic cost as USS is delivered as a single unit.
- * Low civil / foundation cost.
