ISOSCAN® EDS150 / EDS151
6-channel insulation fault locators with integrated current transformers for main (EDS150) and control (EDS151) circuits in IT systems of plants, power stations and ships.
Description
The ISOSCAN® EDS150 (main circuits) and EDS151 (control circuits) work with an ISOMETER® to locate insulation faults in unearthed IT systems. All current-carrying conductors of an outgoing line are routed through the six integrated measuring current transformers.
Key features
- 6 integrated measuring current transformers
- Response sensitivity: EDS150 5 mA, EDS151 0.5 mA
- Alarm response time including display indication of max. 8 s (AC system, IEC 61557-9)
- Up to 88 devices on RS-485 (BMS protocol), monitoring up to 528 circuits
- Cyclical self test
Applications
Insulation fault location in AC, AC/DC and DC IT systems, including DC main circuits in industrial plants, power stations and ships.
