STAMFORD S6 — low-voltage synchronous generator 810–1695 kVA
Country: United Kingdom · Model: S6
The low-voltage brushless generator S6 for sets of about 1–1.7 MVA. It gives 810–1400 kVA at 400 V and 50 Hz and 1000–1695 kVA at 480 V and 60 Hz, with a voltage of 380–690 V, four poles and 1500/1800 rpm. The new core lengths for 1260 and 1400 kVA have an optimized power density.

Description
The S6 replaced the four-pole HC6. Excitation from the PMG sub-exciter separates the regulator circuits from non-linear loads and sustains the steady-state short-circuit current. The standard digital VITA 05 with three-phase sensing has an accuracy of ±0.25 % and a diode failure detector; the DECS150, MX321 or MX341 can be fitted as options. The winding is wire with a 2/3 pitch, the insulation is class H and the cooling is CoreCooling. For the marine version S6L1M the ratings are given for temperature rises of classes B (70 °C), F (90 °C) and H (110 °C) at an ambient of 50 °C. Cores G and H do not allow winding reconnection, while the rest have three-phase reconnection. IP23 and IP44 filters and an IP44 terminal box are available as options.
How to choose
The main choice is made by output, that is 810–1400 kVA at 50 Hz or 1000–1695 kVA at 60 Hz. Below it lies the S5 (450–937 kVA), above it the S7 LV (1550–2800 kVA at 400 V). The S6L1D version is industrial and the S6L1M is marine.

FAQ
What output does the S6 generator have at 50 and 60 Hz?
810–1400 kVA at 400 V and 50 Hz and 1000–1695 kVA at 480 V and 60 Hz. The voltage is 380–690 V, with four poles.
Which voltage regulator is fitted in the S6?
The digital VITA 05 with an accuracy of ±0.25 % as standard. The DECS150, MX321 and MX341 are optional.
Which generator did the S6 replace?
The four-pole HC6. The core lengths for 1260 and 1400 kVA were added with an optimized power density.
Is there a marine version of the S6?
Yes, the S6L1M. Its ratings are given for temperature rises of classes B (70 °C), F (90 °C) and H (110 °C) at an ambient of 50 °C.
Which S6 cores do not allow winding reconnection?
Cores G and H. The other versions have three-phase winding reconnection.
