HF-RT-214 Protection Relay Secondary Injection Tester

Product Overview

Technical Features

1. Current and voltage output accuracy up to 0.05%, smooth waveform and excellent stability to meet all kinds of testing requirements.
2. Handheld compact design with light overall weight for easy carrying and field transportation.
3. Modular internal structure mostly built with imported components, ensuring stable and reliable output performance.
4. Brand-new chassis and operation panel layout with multiple shortcut keys for efficient and convenient operation.
5. 10.1-inch high-definition capacitive touch screen enables intuitive touch control operation.
6. Powered by built-in lithium battery pack; equipped with emergency socket for external spare battery connection, and compatible with power bank power supply.
7. Continuous three-phase 10A current output lasts over 4 hours; standby time exceeds 10 hours.
8. Embedded Linux operating system delivers more stable operation compared with Windows CE system.
9. Testing software adapted to Linux system optimizes touch operation experience; parameter setting and testing functions are simple and efficient.
10. Multiple communication modes available: RS232 serial port, RJ45 Ethernet port and Wi-Fi wireless control.
11. Voltage & Current Test: Detects overcurrent protection, zero-sequence current protection, voltage protection and other action logics of intelligent power terminal devices. Under manual control mode, amplitude, phase and frequency of each channel voltage & current can be adjusted arbitrarily.
12. State Sequence Test: Users can customize testing procedures; the system provides 50 test states. The amplitude, phase and frequency of voltage/current for each state are fully adjustable, and state switching can be triggered by time, button or access contacts. The on/off status of two pairs of output contacts under each state is controllable, which simulates the action of protection outlet contacts and is ideal for single debugging of terminal devices.
13. Group Test: Supports phase-ground, phase-phase, positive/negative/zero-sequence input modes. Amplitude, angle, phase and frequency of analog quantities can be set freely to test impedance characteristics of distance protection. It simulates single-phase/phase-to-phase/three-phase short-circuit faults, distance protection, overcurrent protection, zero-sequence protection, auto-reclosing tests (check synchronization & no-voltage check), post-acceleration tests, as well as transient & conversion faults.
14. Harmonic Test: Each analog channel can superimpose DC component and 1~20 order harmonic components arbitrarily.
15. Waveform Playback: Supports playback of fault recording data in COMTRADE format.
16. Measures pick-up value, reset value and sensitive angle of DC relays including voltage relays, current relays, time relays and three-phase unbalance relays.
17. Mixed output of analog quantity, digital quantity, SV/GOOSE digital signals, satisfying testing requirements for “analog + GOOSE” protection devices.
18. Optical power testing function for ST & LC optical ports.
19. Comprehensive professional protection testing modules: manual test, state sequence, harmonic superposition, group test, under-frequency load shedding, under-voltage load shedding, distance protection, zero-sequence protection, overcurrent protection, percentage differential protection, harmonic braking protection, etc.
20. Abnormal condition handling: automatic detection & alarm for voltage source short circuit, current source open circuit, overheating and signal distortion.
21. Low power consumption design with PWM temperature control system for internal temperature regulation.
22. Automatic firmware upgrade via USB flash disk.
23. Automatically generate test reports, which can be copied and archived via USB disk.
