AC INSULATION GUARD WITH MEASURING LOOP SUPERVISION KPM26x • Direct connection up to 500V line voltage, up to 6,6kV with HV adapter • Continuous supervision of measuring loop continuity • 2-level insulation relays and loop continuity relay • Immune to earth capacitance and voltage surges • For use in land, marine, offshore, sub-sea and ocean floor Installations • Analogue output proportional to meter reading (F-version) Specifications General Auxiliary Supply: Optional Voltage: Contact rating: Analogue Output: F-versions The prime purpose of the digitally controlled KPM26x is basically identical to the “traditional” KPM16x Insulation Guard range. An auxiliary Measuring Input Loop Continuity Monitoring Facility has been added to notify the operator if a measuring loop disruption may cause the meter to read a too high insulation level. The unit has C/O relay outputs for Warning, Alarm and loop failure. The Alarm relay is fail to safety configured. 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. Trip levels and delays are settable on unit rear. Temperature: Weight: Front protection: Only ONE KPM26x can be connected to each IT-system. The ohmmeter and the triple-zone status LEDs give at a glance the clear safety message: - ALARM (red zone) - WARNING (yellow zone) - HEALTHY (green zone) INTELLIGENT SETTING ASSISTANCE KPM263x has a built-in Assistance tool for setting/verification of the trip levels and the analogue output. General When either the Warning or Alarm potmeter on the rear is operated by user, the meter goes into Assistance Mode and meter reading and analogue output will reflect the potmeter setting. How to set alarm levels: Firstly adjust potmeter fully clockwise (see that meter goes to the top), then adjust potmeter down to required Warning or Alarm setpoint. Without any movement of potmeters, the meter will revert to normal Insulation Monitoring Mode after approximately 10 seconds. How to test analogue output signal: Adjust any trip level potmeter to activate Assistance Mode. Example: On a 4-20mA output, adjust potmeter fully anti clockwise for 4mAand fully clockwise for 20mA. The KPM263x range is designed to comply with specification AODC035 “Code of Practice for the Safe Use of Electricity Under Water” issued by IMCA. The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies. IDV MEASURING PRINCIPLE Insulation is measured between the complete galvanically interconnected AC network and its protective earth. 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 theAC network, the processing time for KPM26x is approximately 400mS. MEASURING LOOPALARM A sensing resistor is mounted at the furthest end of the monitored loop in a separate Loop Resistance Sensor Module (LRSM-1,4 or LRSM-5). There are no restrictions on distance from the sensing resistor to the KPM26x unit. There is a fixed delay of 60 seconds on the loop failure alarm. The Loop alarm will notify the operator by activating LED LOOP FAILURE and trip relay 3. A disruption in the input measuring loop may cause the guard to falsely read a too high insulation level. The Measuring Input Loop Continuity Monitoring Facility is of special importance during lasting standby conditions (motors, lanterns etc). 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 is avoided. OUTPUTS All F versions have an isolated analogue output proportional to meter reading. If output is used for remote meter reading, we recommend 0-1mAfor the slave indicator. SAFETY When a voltage adapter (CHx) is used the signal to terminals 4 and 6 on KPM261x and KPM263x is limited to a safe level, avoiding any dangerous voltage exposure to personnel.
