ENERGOTEST ARC PROTECTION ZL1
ENERGOTEST ARC PROTECTION ZL1
Basic realy PL-1 futures:
- sends tripping signal (3 switching contacts);
- detect voltage drop on switchgear's bus-bars;
- gets an information about input state of fiber optic loops;
- generates alarm signals
Optical fiber loops
The main function of optical fiber loops is detection of an arc fault light. This loops are not covered, and they are using the effect of side penetration of light. The maximal length of one loop is 60m (optionally 100m). Each relay has two loops.
ENERGOTEST ARC PROTECTION ZL4
ENERGOTEST ARC PROTECTION ZL4
ZL-4 is on innovative protection with module structure - central unit and bay units (max. 99 for one central unit). The communication between units is executed by fast CAN bus. Together with CAN bus, power supply circuits are distributed. Functions such as voltage measurement and power supply are centrally grouped. In new construction a lot of proven solutions, like front light detectors have been used. The key advantage of ZL-4 is the possibility of selective tripping of bays in witch the arc fault has occurred. The protection is dedicated to the modern closed switchgears.
The idea of ZL-4 installation in the switchgear
The signal from voltage measurement bay is leaded to the protection relay (under voltage condition). Central unit is connected with bay units by CAN bus. Each bay unit has up to four front detectors placed in different sectors of protected switchgear bay. In case of detection arc light in first zone, the whole switchgear is tripped off. In case of detection arc light in second zone, only this bay is tripped off, in which the light has been detected.
CAMTO弧光偵測電驛(系統) Arc Detection Relay
Major highlights of the new ARC-detector unit from Camto A/S type: 601E0100 & 601E0900:
Input voltage: 9-32VDC (601E0100) 110Vac/230Vac (601E0900)
Four individual detector zones
Unlimited numbers of sensors for each sensor zone
The possibility of series connection of sensors in the same zone (savings on sensor cables
and installation costs)
100% self-test feature option; even tests of the optical parts are included
Pre-detection of small levels of fault
Simple serie code output for event status (PLC interface)
Trip coil outputs as latched and open contacts
Combination of sensor types like smoke, ARC, humidity, temperature and levels are
available
Standard DIN unit with spring terminals
Realtime eventlog with time and date information for fault status
Simple PC interface (MSP) for monitor and setting use
Low unit and installation costs

SEL 487B 87B保護電驛
The SEL-487B Relay provides bus current differential protection, circuit breaker failure protection, and
backup overcurrent protection. The relay has 18 analog current inputs and three analog voltage inputs. For
buses with no more than six terminals, use one SEL-487B in a single-relay application. For buses with seven
to nine terminals, use two SEL-487B relays. For buses with up to 18 terminals, use three SEL-487B relays;
each relay provides up to six dedicated zones of protection.
