Keytek 711A/H Surge Generator
The KeyTek 711 A/H surge generator is complete, turn-key instrumentation for
generating and coupling to an AC or SC power line, all three surge waves-both impulsive and
oscillatory-required by IEEE Standard 587-1980, for both long and short branch circuits.
Selectable surges for:
- Short branch circuits
- 1.2 x 50µs impulse, to 6kV OCV*, 8 x 20µs impulse to > 3kA SCI* (stored energy, 216 joules)
- 0.5µs/100 kHz ring wave (damped cosine): to 6kV OCV*, 500A SCI* (stored energy, 7.2 joules)
- Long branch circuits - 0.5 µs/100 kHz ring wave: to 6kV OCV*, 200A SCI* (stored energy, 7.2 joules)
- Switch-selectable polarity
- Meter to set peak output surge
- Floating synch output just prior to surge
- Full interlock system prevents surging unless all interlocks (including external) are closed
Includes:
1. Model 711A Surge Generator mainframe
2. Model P1 .5µs/100 kHz ring wave plug-in Surge Network
- 6kV, 0.5µs/100 kHz ring wave;
- 200A and 500A
- Q ~ 3 and Q ~ 10
- IEEE Std. 587-1980 (Cat. A plus first half of Cat. B); UL943, 217, 268
3. Model P3 1.2 x 50µs impulse plug-in Surge Network
- 1.2 x 50µs, 6kV
- 8 x 20µs, ~ 3kA
- IEEE Std. 587-1980 (second half of Cat. B); IEC 664
4. Model F31 Surge Coupler/Filter
Selectable surge coupling modes:
- Normal mode: line 2 to line 1
- All three common modes:
line 1 to ground
line 2 to ground
lines 1 and 2 to ground
- Power line:
0-277 V, 50-60 Hz
0-120 V dc
To 10A continuous, 15A intermittent
