ISOMETER® isoPV1685/isoPV1685PFR

ISOMETER® isoPV1685RTU/isoPV1685P

  • Application photovoltaic systems up to AC 1000 V/DC 1500 V
  • Separately adjustable response values 200 Ω…1 MΩ
  • Automatic adaptation to the system leakage capacitance up to 2000 μF
  • Interface selectable RS-485 or Modbus

The device is used for insulation and residual current monitoring of large photovoltaic systems up to AC 1000 V/DC 1500 V designed as IT systems. The measurement method specially developed for slow voltage fluctuations (MPP-Tracking) monitors the insulation resistance even in systems equipped with large solar generator panels where extremely high system leakage capacitances against earth exist due to interference suppression methods. Adaptation to system-related high leakage capacitances also occurs automatically.

The device generates locating current pulses required for insulation fault location. That allows the localisation of the insulation fault using permanently installed or mobile insulation fault locators. Integrated residual current monitoring allows fast signalling of a measured insulation faults on the AC side (inverter, transformer).

Caratteristiche

Only device version isoPV1685P provide a locating current injector.

  • Insulation monitoring of large-scale photovoltaic systems
  • Measurement of low-resistance insulation faults
  • Separately adjustable response values Ran1 (alarm 1) and Ran2 (alarm 2) (both 200 Ω…1 MΩ) for prewarning and alarm. Ran1 ≥ Ran2 applies.
  • Automatic adjustment to high system leakage capacitances up to 2000 μF, selectable range
  • Connection monitoring of L+, L- for reverse polarity (DC only)
  • Integrated locating current injector up to 50 mA (isoPV1685P only)
  • Device self test with automatic message in the event of a fault
  • Alarm relays separately adjustable for insulation fault 1, insulation fault 2
  • CAN interface to output measured values, statuses and alarms
  • RS-485 interface
    – isoPV1685P: BMS bus, e.g. to control the insulation fault location
    – isoPV1685RTU: BMS bus or Modbus (can be switched using the DIP switch)
  • μSD card with data logger and history memory for alarms
