Pragati Electrical Pvt. Ltd. was
established in 1975, by electrical engineers having rich experience in the field
of designing and manufacturing of instruments transformers.
Pragati has successfully developed many
products as per the requirements of indoor Switchgear industry and conforming to
Indian and International Standards.
Pragati is one of the leading manufacturer
of Epoxy Resin Cast Indoor medium voltage Instrument Transformers in India. They
are manufactured in a modern factory at Navi Mumbai.
All products are type tested at recognized
institutes such as CPRI/ERDA etc.
Pragati's major
customers in India include Switchgear manufacturers such as Siemens, ABB, BHEL,
Alstom, NGEF and power utilities such as Tata Power, CESC, BSES, BEST, etc.

CURRENT TRANSFORMERS:
Indoor type Current
Transformers are available in the following variations.
1. Block-type (Post Type /
Wound Primary)
2. Bar-type (Embedded bar)
3. Window type (Bus-Bar to be inserted through the window opening by the
customer)
Casting is done in a single process i.e. HV and LV windings are completely
encapsulated in Epoxy Resin.

| Dry Type |
| Can be installed in any position |
| Non Hygroscopic / Suitable for tropics |
|
| ROUTINE TESTS |
| Ration and Phase angle error tests. |
| Induced and applied voltage tests. |
| Partial discharge tests. |
| Tests are done as per National /
International standards. |
|
 |
| POTENTIAL / VOLTAGE TRANSFORMERS
Indoor type Voltage Transformers are available in the following two
variations:
1. Single pole insulated (Earthed type)
2. Double pole
insulated (Unearthed type)
|

Casting of the core and windings
assembly is done in a single process i.e. HV winding, LV winding(s) and core
are completely encapsulated in epoxy resin. |
| Primary winding is resin impregnated
prior to casting. |
| |
| ROUTINE TESTS |
| Ration and Phase angle error tests. |
| Induced and applied voltage tests. |
| Partial discharge tests. |
| Tests are done as per National /
International standards. |

BUS-DUCT CURRENT TRANSFORMERS / RING TYPE
CURRENT TRANSFORMERS
Bus Duct CTs are normally ring type
Current Transformers, suitable for
operation in Bus-Duct or Generator Terminal enclosures. The inside diameter of
the CT depends on the size of the conductor of the customer.
