Our Major Products:

Numerical Protection Relays :

  • Numerical Relays has large number of protection functions. The unique programmability allows the user to form its own logic suitable for existing site conditions. This saves a lot of wiring and panel space and becomes very cost effective. The relay is having open communication protocol, which allows monitoring the substation remotely.

  • ASHIDA has designed economical & reliable Multifunction Draw-out/Non draw-out Feeder Protection Relay ADR245B/ADR241A/ADR241B/A21F provides integrated Protection, Control and Monitoring functions for Sub Transmission Lines, Underground cables and Distributed Feeders.Protection & Control System.

  • Relay designed with fast and selective tripping ensures the stability and availability of electrical power system.

  • Transformer Differential Protection Relay ADR233B/A21T provides integrated Protection, Control and Monitoring functions for Transformers.

  • Motor Protection Relay ADR244A/ADR244B/A21M provides integrated Protection, Control and Monitoring functions for Induction motors.

  • Generator Protection Relay ADR245G provides protection, control & monitoring of distributed generator to achieve sensitivity and selectivity on phase and ground faults.

  • Normally all electronics units require some sort of auxiliary power supply for its own operation. Self Power RMU Protection Relay ADR241S is a special protection relay which can take power supply from the current it is monitoring. This unique feature makes ADR241S relay well suitable for RMU (Ring Main Unit).

  • ASHIDA is one of the major Suppliers of protection system for 25kV railway traction system. ASHIDA has developed complete protection scheme for Indian Railways.

  • SCADA :

  • SCADA system is a very important tool to monitor power system effectively. ASHIDA has developed very versatile SCADA system software which can communicate with variety of Relays / RTU having different protocols such as IEC 60870-5-103, DNP 3, MODBUS, IEC 61850 etc.

  • Energy Management Software are very crucial to co-gen plants, industries etc to analyse the import/export energy etc. These reliable software from ASHIDA are a part of the ASCADA suite.

  • Proven SCADA systems with in-house development of hardware (RTU) as well as the SCADA software.

  • ASHIDA has Designed, Developed & Perfected SCADA (Supervisory Control & Data Acquisition System) System especially for Substation Automation for Electrical Utility application.

  • The concepts we have used in our ASHIDA SCADA system employs Remote Terminal Units (RTUs), Station Controller, Intelligent Electronic Devices (FCCM) etc. A-SCADA can integrate different makes of Bay Controller Units (BCUs), Numerical Protection Relays and Multi Function Meters with integration of multiple protocols.

  • ASHIDA SCADA system covers complete Energy Management System, Alarms & Status monitoring, recording & controlling outputs. It measures Digital Inputs (DI), Analog Inputs (AI) & Digital Outputs (DO) and executes complete protection Relay analysis.

  • Control & Relay Panels :

  • ASHIDA Numerical Protection & Auxiliary Relays offer a perfect solution for integration into Substation Automation System. ASHIDA manufactures Control & Relay Panels for protection of Feeders & Transformers at 11kV to 220kV voltage levels. ASHIDA also gives solution for Line Differential Protection, Bus Bar & Bus Coupler Protection, Integrated Motor Control Systems etc.
