Description

KPM161

Insulation Monitor, System Voltage up to 690VAC, Output Relays and Optional Analog Output

  • Direct connection up to 690V line voltage
  • Monitoring during both live and standby conditions
  • For use in land, marine, offshore, sub-sea and ocean floor Installations
  • Triple-zone insulation monitoring
  • Comply with AODC 035 Code of Practice
  • “Megger” – safe to 1,4kVDC when aux power is OFF
  • Immune to earth capacitance and voltage surges
  • Analogue output proportional to meter reading (F-version)
Application
Our the digitally controlled KPM161x series monitors insulation level between a non-grounded (IT) AC mains and its protective earth, regardless of whether the mains is live or non-live (standby). The unit is for land, marine, offshore, sub-sea and ocean floor use.
An AC or DC auxiliary voltage is required for the unit, if powered from a separate source the network can also be monitored during standby conditions. Only ONE KPM161x can be connected to each IT-system.
The ohmmeter and the triple-zone status LEDs give at a glance the clear safety message:
  • ALARM
  • WARNING
  • HEALTHY
General
IDV MEASURING PRINCIPLE
Insulation is measured between the complete galvanically interconnected AC network and its protective earth. The unit injects a sequentially coded measuring signal into the monitored system. The signal flows to ground via the path of the insulation fault, the level of flow indicates the insulation resistance. The measuring accuracy is not influenced by any normal kind of load attached to the AC network. Trip levels and delays are settable on unit rear. A trip LED flashes when the trip level is passed, the relay trips when the delay has elapsed. The timer resets if the fault is removed during countdown.
MEGGER SAFE
When auxiliary power is OFF the unit input is automatically protected against “megger” test voltages up to 1.4kVDC, and incorrect measurements caused by the unit’s input impedance are avoided.
OUTPUTS
All F versions have an isolated analogue output proportional to meter reading. If output is used for remote meter reading, we recommend 0-1mA for the slave indicator.
SAFETY
The KPM161x range is designed to comply with specification AODC035 “Code of Practice for the Safe Use of Electricity Under Water” issued by IMCA.
INTELLIGENT SETTING ASSISTANCE
KPM161x has a built-in Assistance tool for setting/verification of the trip levels and the analogue output.
When either the Warning or Alarm potentiometer on the rear is operated by user, the meter goes into Assistance Mode and meter reading and analogue output will reflect the potentiometer setting.
