Testing Instruments for Various Testing

1. 3 phase Power System Simulator, Make Doble, Type: F6150. Quantity: 3 Nos.

Power System Simulator uses a signal processing power amplifier to simulate the operation of protective relays for various testing applications. This Power System Simulator can check protection systems and verifies protection settings by simulating system events.
This Power System Simulator tests all the protective relays covered under IEEE device Nos. This Power System Simulator is supported by a versatile and automatic protection software F6 Test.

Power System Simulator

The F6000 Control Panel software is for quick manual style interactive testing. This Simulator can also be used for calibration/testing of transducers and metering applications, including the 0.2 class standard metering system.

2. ISA Make: T3000 : Sub-station Test System : Quantity 3 Nos.

This is a sub-station Maintenance and Commissioning test equipment. It’s a Multi-Function system for testing substation equipment such as,
  • Current Transformers,
  • Voltage and Power Transformers,
  • Protection Relays,
  • T3000 can carry out testing operations during the commissioning and maintenance of substations.
  • It tests relays of all types (voltage, current/power, frequency and df/dt) and current and voltage transformers.
  • T3000 has a powerful multi-meter and phase angle meter with oscilloscope functions.
