Ratings Definitions (according to the standard ISO8528.1:2005)

PRP - Prime Power

It is defined as being the maximum power which a generating set is capable of

delivering continuously whilst supplying a variable electrical load when operated

for an unlimited number of hours per year under the agreed operating

conditions with the maintenance intervals and procedures being carried out as

prescribed by the manufacturer. The permissible average power output over 24

h of operation shall not exceed 70 % of the prime power.

LTP - Limited-Time running Power

It is defined as the maximum power available, under the agreed operating

conditions, for which the generating set is capable of delivering for up to 500 h

of operation per year (whose no more than 300 for continuative use) with the

maintenance intervals and procedures being carried out as prescribed by the

manufacturers.

No overload capability is available.

Mechanical characteristics

0530, BS 4999-5000

Mechanical structure

Robust mechanical structure which permits easy access to the connections

and components during routine maintenance check-ups.

Voltage regulator

Voltage regulation with DSR. The digital DSR controls the range of voltage,

avoiding any possible trouble that can be made by unskilled personnel.

The voltage accuracy is ±1% in static condition with any power factor and

with speed variation between 5% and +30% with reference to the rated

speed.

Windings/Excitation system

Generator stator is wound to 2/3 pitch. This eliminates triplen (3rd, 9th,

15th …) harmonics on the voltage waveform and is found to be the

optimum design for trouble-free supply of nonlinear loads. The 2/3 pitch

design avoids excessive neutral currents sometimes seen with higher

winding pitches.

ALTERNATOR

Windings/Excitation system

MAUX (Standard)

The MAUX MeccAlte Auxiliary Winding is a separate winding within the

main stators that feeds the regulator. This winding enables to take an

overload of 300% forced current (short circuit maintenance) for 20

seconds. This is ideal for motor starting requirements.

PMAUX (optional)

Alternator can be equipped with the optional PMAUX (Permanent Magnet

Generator) which matches the performance and is capable of supporting

both linear and distorted loads.

Insulation/Impregnation

Insulation is of class H standard.

Impregnation is made with premium tropicalized epoxy resins by dipping

and dripping.

High voltage parts are impregnated by vacuum, so the insulation level is

always very good.

In the high-power models, the stator windings undergo a second insulation

process.

Grey protection is applied on the main and exciter stator to give enhanced

protection.


Reference Standards

2.5 Reference Standards

Alternator manufactured according to , and complies with , the most

common specification such as CEI 2-3, IEC 34-1, EN 60034-1, VDE 0530,

BS 4999-5000, CAN/CSA-C22.2 No 14.
