TISP4xxxH3/M3BJ Series for LCAS Protection
Protector Voltages
Protector working and protection voltage design calculations for the LCAS are described in the IEEE Std. C62.37.1-2000, IEEE Guide for the
Application of Thyristor Surge Protection Devices, pp 40-43. These calculations comprehend:
the temprature variation of LCAS voltage ratings,
increase in protection voltage with ambient temperature rise, long term a.c. heating and under impulse conditions,
decrease in working voltage with ambient temperature fall,
ground-backed and battery-backed ringing configurations (see Figure 13).
These calculation techniques were used to set the TISP ? part voltages. Using these TISP ? parts allows normal system voltage levels of ± 100 V
on TIP and ± 180 V on RING without clipping at 25 ° C. At 0 ° C ambient, these voltage levels become ± 97 V on TIP and ± 174 V on RING. Under
open circuit line conditions, this means that the peak ringing voltage cannot exceed ± 174 V for equipment operation down to 0 ° C ambient.
Assuming a battery voltage of 48 V ± 2.5 V and battery-backed ringing, the maximum peak a.c. ring voltage is 174 V - 50.5 V = 123.5 V or 87 V
rms. The working voltage of ± 97 V on TIP is more than half the ± 174 V working voltage on RING. As a result, the TIP working voltage does not
represent a limitation for systems where the TIP return resistance is equal or less than the RING source resistance.
For balanced impedance ground-backed ringing, the maximum peak a.c. ring voltage under short line conditions (short between TIP and
RING) is limited by the TIP working voltage of ± 97 V. In the negative ring polarity, the limit of the voltage is made up from half the battery
voltage plus half of the peak a.c. ring voltage. The maximum peak a.c. ring voltage is 2 x (97 - 50.5/2) = 143.5 V or 101 V rms.
Line test voltage levels must be considered, whether they be applied by using LCAS switches or separate electro-mechanical relays. For these
TISP ? parts, the applied test voltage should not exceed the lowest working voltage, which is ± 97 V.
