shall be made to compensate for the overhanging weight of the pole. For this purpose the overhanging

portion of the pole may be supported on movable trolley or similar device.

3. The pole shall be rigidly supported at the butt end at a distance equal to the agreed depth of plating i.e.

1.5M

4. Load shall be applied at a point 600mm from the top of the pole and shall be steadily and gradually

increased to the design value of the transverse load at the first crack. The deflection at this load shall be

measured.

A prestressed concrete pole shall be deemed not to have passed the test if visible cracks appear at a stage

prior to the application of the designed transverse load for the first crack.

The load shall then be reduced to zero and increased gradually to a load equal to the first crack load plus

10% of the minimum ultimate transverse load and held up for two minutes. This procedure shall be

repeated until the load reaches the value of 80% of the minimum ultimate transverse load and thereafter

load until failure occurs. Each time the load is applied, it shall be hold for two minutes. The load applied

to prestressed concrete pole at the point of failure shall be measured to nearest five kgs.

The poles shall be deemed not to have passed the test if the observed ultimate transverse load is less than the

designed ultimate transverse load.

The transformer along with all fittings such as metering cubicle should be suitable for installation and operate as per H-pole drawing (enclosed as Annexure-A). The transformers shall have the following CSP features: i) Internal HV Fuse on the HT side of transformer: Specification for the HV fuse: Expulsion/any other suitable type of fuse shall be placed in series with the primary winding. The fuse shall be mounted normally inside of the primary bushing for the three phases and connected to the high voltage winding through a terminal block. This has to protect that part of the electrical distribution system which is ahead of the distribution transformers from faults which occur inside the distribution transformers i.e. either on the windings or some other part of the transformers. It shall be ensured that the fuse does not blow for faults on the secondary side (LT side) of the transformer i.e. the blowing characteristics of the fuse and LT breaker shall be so coordinated such that the fuse shall not blow for any faults on the secondary side of the transformer beyond LT breakers and those faults shall be cleared by the LT breaker only.

(ii) Internally mounted oil immersed LT breaker on the LV side of the transformer. 3 Pole LT Circuit breaker: All LT faults after the breaker shall be clear by this breaker. As such it shall be designed for perfect coordination with HT fuse link. The Bidder shall furnish the time/current characteristics of LT circuit breaker and 11 KV fuses for various current multiples. The two characteristics shall be drawn on the same sheet to indicate coordination between the circuit breaker and fuse. The Bidder shall carry out coordination test as indicated above and this forms one of the tests as for acceptance test. The breaker shall be coordinated thermally with the transformer design to follow closely the variations of coil temperature due to fluctuating load and ambient temperatures. The breaker trip setting shall be kept considering continuous loading of 130% for 6-hours duration at an average ambient temperature of 40

o C.

This is to be accomplished by connecting the breaker in series between the secondary windings and the secondary bushings. The breaker shall be located in the same oil as the core and coil assembly so that the bi-metal are sensitive to the temperature of oil as well as the load current. The Circuit breaker shall also be closed and opened manually standing on ground. The current carrying parts of breakers shall be copper plus a set of copper tungsten current interrupting contacts. The Cross section of the current carrying parts of the breakers shall withstand the full load current at a current density not more than 2.5 A/Sq.mm (for additional mechanical strength the area should be more). iii) The supplier can also offer the transformer with MCCB (Specifications attached) mounted on it instead of in-built breaker. 36. Earthing Connections Two earthing connections shall be provided with connection facilities withs 25 x 6 mm GI strip. The bolts shall be located on the lower side of the transformer and shall be of M12 size. The earthing should be suitable to carry the full fault current. Further, there should be separate earthing for the STAR point on LT side as well as on the body of the transformer. 37. FITTINGS: Each transformer shall be provided with all the required fittings as per Annexure-D. 38. PENALTY FOR NON PERFORMANCE: 38.1. Purchaser reserves the right to reject any transformer during the test at supplier’s works, if it is found that actual measured losses are more than the values quoted by the bidder 38.2. Purchaser reserves the right to reject any transformer during the test at supplier’s works, if the temperature rise exceeds the guaranteed values. 38.3. Purchaser reserves the right to reject any transformer during the test at supplier’s works, if the impedance values differ from the guaranteed values including tolerance. 38.4. Purchaser also reserves the right to retain the rejected transformer and take it into service until the Bidder replaces it with a new transformer at no extra cost. The delivery as per contract will be counted when the new transformer as per specification is provided by the manufacture. 39. PROTOTYPE TRANSFORMER The prototype transformer on which type test got conducted shall be supplied to UHBVN/ DHBVN duly sealed after completion of type testing in the beginning itself before commencement of supply. The bidder shall furnish an affidavit that all his balance transformers shall meet with prototype in all respects ( internal & external ). The Nigam can randomly select any transformer & verify the internal / external details with the prototype sample at any time during warranty period. Type test certificates for the tests carried out on prototype of same specifications shall be submitted along with the bid. The purchase may select any transformer from the offered lot for inspection during subsequent lots for carrying out temperature rise test from any Govt. approved lab. Further the purchaser may select the transformer for type tests randomly. 40. CHALLENGE CLAUSE: - "The material offered/received after the inspection by the authorized inspecting officer may again be subjected to the test for losses or any other parameter from any Testing House/in-house technique of the Nigam & the results if found deviating un-acceptable or not complying to approved GTP's the bidder shall arrange to supply the replacement within thirty (30) days of such detection at his cost including to & fro transportation." In addition to this penalty @10% of cost of the inspected lot of material shall be imposed. Director/Technical-I
