Pump Seal Protection – PSP1

Microprocessor based monitoring relay to measure moisture in a submersible pump. Due to the advanced design of the unit a high accuracy and safety is achieved. Response delay are incorporated to prevent nuisance tripping. The unit energises on application of supply. If the current through the probes is more than 20uA or the resistance is smaller than 10 Mohm, the relay will de-energise after 10 sec. The relay will energise if the current is less than 15uA and the resistance is more than 1.4Mohm.

 
Features:
 
  • Microprocessor based design
  • High accuracy analogue converter
  • Repeatable deviation: <0.2%
  • Power supply ON and Relay ON LEDs

Phase Sequence Monitor – SF1
Phase Sequence Monitor – SF1

The SF1 Monitors negative phase sequence (NPS) voltage to detect phase failure, phase reversal and phase imbalance. The NPS voltage of the unit can be djusted from 7-15%. When any of these faults occur the unit will de-energize. The relay will only re-energize if the supply voltage corrects itself. The unit will not react to a balanced voltage variation

 
Features:
 
  • Monitoring relay for 3-phase voltage control
  • Measures if all 3 phases present and in sequence
  • Detection of phase asymmetry
  • Insusceptible to balanced supply voltage variation
  • Insensitiveto regenerated EMF
  • Fastresponse to reverse phase sequence
  • Relay ON LED
  • Output 10A SPDT
