ELECTRIC POWER DIVISION
Transformer Wireless Load Monitoring System (DTMS),
Fault Current Path Monitoring System (FPI), POWER CT
This, where installed, will provide a mean of indicating the passage of fault current along the medium voltage overhead line and It shall be made of Fault detection systems with LED falsh0ing and wireless communication to be installed on Medium Voltage Overhead Electric networks. It must be positioned in strategic locations, for example at the start of each branch and at the location of manual switchgear. Send fault location message to pre-set person
Feature
- It is designed monitoring of overhead MV line
- The LED indicates fault type as permanent and transient
- Set up parameter by RF modem
Description
- Easy to detect fault location on MV line and do faster recovery
- LED light is visible from a 360⁰
Inrush filtering
- It depends whether it is inactive or active in case that the current on conductor is higher than pre-set fault current.
Reset
- By FCS program / By Magnetic / Reset after the set time has elapsed
Advantages
- Improve revenue by shorten rounding time & recovery time
- Reduce consumer complaining by outage managemen
