Small-scale burning down instrument MPU-3 Phoenix is intended for burning down of damaged 380V-10kV cable insulation for further damage area detection by means of induction or acoustic method.
Fourth DC power source – high-voltage burning down instrument VPU-60 – can be connected to MPU-3 via external diode array DL-1 if necessary. Burning complex consisting of MPU-3, DL-1 and VPU-60 provides continuous stepless burn down from 60kV to 0.
Advantages of MPU-3 Phoenix:
lightweight and compact;
low power consumption (the instrument can be supplied by 6kVA autonomous electric power station);
optimum energy release in the damaged area, quick burn down;
possible long-term operation even under high ambient temperature;
very efficient for occluding cable breakdown detection.
