STAMFORD P80 LV — low-voltage synchronous generator up to 1000 V, up to 5100 kVA

Country: United Kingdom · Model: P80 LV

The low-voltage version of the P80 series (LVI/LVSI 804) for voltages up to 1000 V at 50 Hz (1500 rpm) and 60 Hz (1800 rpm). The four-pole generator gives up to 4200 kVA at 50 Hz and up to 5100 kVA at 60 Hz, with a series range of 1920–5100 kVA. The core lengths are marked with the letters R, S, T, W, X.

Series output: 1920–5100 kVA; up to 4200 kVA (50 Hz) / 5100 kVA (60 Hz)
LV voltage: up to 1000 V (50/60 Hz)
Number of poles: 4 (1500/1800 rpm)

Description

The generator is brushless, with excitation independent of the PMG on the shaft, so the regulator receives a stable supply and the steady-state short-circuit current is maintained. The standard digital DM110 (the manual also lists the MA330 and DECS150) holds ±0.25 % and has under-frequency roll-off protection UFRO. The stator with a 2/3 pitch eliminates harmonics that are multiples of three, and the full damper winding reduces oscillations in parallel operation. The insulation is class H, the protection is IP23, and the rotors are balanced to BS6861 part 1, grade 2.5. Six winding leads are brought out into a steel terminal box on the non-drive side, where the AVR is also located. The design altitude is up to 1000 m and the temperature up to 40 °C, and the operating temperature range is from −15 to +40 °C.

How to choose

If the generator voltage is up to 1000 V, this low-voltage item is used, and the medium- and high-voltage P80 versions are considered separately. The series starts at 1920 kVA, so for lower outputs see the S6 (810–1400 kVA at 400 V) or S5 (450–937 kVA). The core length R, S, T, W or X is selected for the required output.

FAQ

What output does the P80 LV generator have?

Up to 4200 kVA at 50 Hz and up to 5100 kVA at 60 Hz, with a series range of 1920–5100 kVA. The voltage is up to 1000 V.

Which voltage regulator is fitted in the P80?

The digital DM110 with an accuracy of ±0.25 % as standard. The manual also names the MA330 and DECS150.

Which standards is the P80 built to?

To BS EN 60034 and to sections of BS5000, VDE 0530, IEC 60034, CSA C22.2-100 and AS1359.

Is the P80 suitable for non-linear loads?

Yes, the stator with a 2/3 winding pitch eliminates harmonics that are multiples of three. The full damper winding reduces oscillations in parallel operation.

What conditions is the P80 designed for?

An altitude of up to 1000 m and an ambient temperature of up to 40 °C. The operating temperature range is from −15 to +40 °C.
