isoPV and AGH-PV

Ground Fault Detector for Ungrounded Solar Arrays up to 1100 V And Isolation Tester Prior to Array Startup (Grounded and Ungrounded)

Description

Designed specifically for photovoltaic systems, BENDER's isoPV ground detector provides early indication of ground faults before leakage current may even be present. The isoPV is specifically designed for PV systems and detects both AC and DC ground faults by monitoring the system's insulation resistance. The isoPV's digital display shows the insulation resistance in real-time. Alarm LEDs provide visual indication of an alarm state. Two voltage-free SPDT alarm contacts are available. The isoPV is compatible with BENDER's advanced communication system for remote visualization capabilities. The isoPV may also be used for determining PV circuit isolation prior to system startup per upcoming requirements in the 2014 NEC.

Function

When the insulation resistance from system to ground falls below the set response value, the alarm relays switch and the alarm LEDs activate. Two separately adjustable alarmcontacts can be set to a prewarning and main warning alarm. The measured value is indicated on the LCD display or an externally connectable measuring instrument. A fault storage setting allows the device to reset automatically or require a manual reset. An external and internal test/reset can be activated remotely or on the device. A comprehensive INFO menu displays additional information such as the system's leakage capacitance. The isoPV monitors the equipment ground connection to ensure proper operation. The device's easy-to-use onboard menu manages all settings via the detailed LCD screen.

Additional Features

• History memory with real-time clock to store up to 300 timestamped event records
• Galvanically isolated RS-485 interface for data exchange with other Bender devices and communication gateways
• Standby contacts and RS-485 communication for operating multiple ground fault detectors in systems tied together with tiebreakers or interlocks
• Galvanically isolated analog output, 0(4 )…20 mA

Use in Interconnected Ungrounded Systems

Only one BENDER insulation monitor may be active when several ungrounded systems are coupled together. The disconnect relays and control inputs F1/F2 integrated into the iso-PV guarantee no interference with other BENDER devices when system coupling is activated.
