Protection Relay
HYC461 ACR controller is a new generation of digital relaying control terminal produced by HEAG. It can protect, control, measure and monitor the grid with voltage below 40.5kV. It is suitable for a variety of system operating modes, including isolated neutral system, resistance-grounded system and arc suppression coils grounding system.
The power distribution automation system is consist of the main substation, data communication system and feeder automatic terminal which is the connector of automatic system and primary device. FTU Power distribution automatic telemetry terminal (HY-PFT2C2W) is the core unit of HYS-8000B power distribution automatic system.
HYP2692 communication manager is one of important part of substation automation system. It is used in applications of miscro-comp uter prote ction, data communication between electronic devices (eg. automatic devices, detector) and main computer system of substations or grid automation systems. It realizes the wholly distributed mode system.
HYP600S is a kind of programmable protection device ,characterized in high-capacity and Resource Redundancy. It applicable for network protection, control, measuring and monitoring of grid with rated voltage no higher than 40.5kV. It can be configured to protect circuit, capacitor group, electric motors, It also applicable for different main wire connection, like a single bus, dual-bus and multi-bus wiring. It is also available for different type of grids , just as ungrounded neutral contact system, the blow-out coil grounding system and the low resistance grounding system.
HYP600 series microcomputer programmable protection relay is suitable for 110kV or below circuit as an protector, controller and monitor for the line, fuse group, motor, power transformer, three-phase asynchronism motor and parallel fuse group.
HYP400 digital microcomputer programmable relay is provided for electricity system of rated voltage 40.5kV and below for protection, controlling, measurement and monitoring purposes. It comprises of circuit, input/output line, capacitor, monitor and protective PT. It is suitable for various systems with different connections, such as non-neutro-earthing system, low resistance earthing system and arc suppression coil earthing system.
HYP-1000 series is a kind of microcomputer monitor and control device which progressed by advanced technology, it is a special design of microcomputer monitor and control device for under 12kV power used of the area of electric power, traffic, petroleum, chemical industry and architecture and so on.
