The RDJB-802H Handheld Relay Protection Tester is designed for power grid companies, power plants, power construction firms, protection device manufacturers, petrochemical enterprises, and rail transit traction power supply systems. It is also suitable for other users working with electrical secondary equipment in operation, maintenance, and debugging. The device has a built-in large-capacity lithium battery. It is lightweight, compact, and easy to operate. It is especially useful for outdoor maintenance tests of power system distribution network automation devices. It can also perform action logic tests of protection devices.
Products Features
10-inch HD LCD touch screen. No physical buttons. Full touch operation, simple and convenient.
Lightweight and portable. The latest tool for debugging personnel.
Supports multiple connection methods. RS232 serial port, RJ45 Ethernet, and wireless WiFi control.
Modular internal structure. Mostly imported components. Stable and reliable output.
Built-in large-capacity rechargeable lithium battery. Standby time over 8 hours. Continuous working time over 4 hours.
New chassis and operation panel design. Multiple shortcut keys for fast and efficient operation.
Complete self-protection function. Includes current overheat alarm, voltage short-circuit protection, overheat protection, and overload protection.
Voltage and current menu. Supports testing of overcurrent protection, zero-sequence current protection, voltage protection, and other logic functions of intelligent terminal devices. In manual mode, users can freely adjust amplitude, phase, and frequency of each voltage and current.
Status sequence menu. Users can customize test modes. The program provides 50 test states. Voltage, current amplitude, phase, and frequency are fully adjustable. Switching between states is controlled by time, key, or open contact. Each state allows free control of two pairs of opening outputs, simulating protection outlet contact action. Very convenient for terminal device debugging.
Group test menu. Supports phase-ground, phase-phase, and sequence component inputs. Amplitude, angle, phase, and frequency of analog signals can be set freely. Enables testing of distance protection impedance characteristics. Can simulate single-phase, two-phase-to-ground, and three-phase short circuits. Also supports distance, overcurrent, and zero-sequence protection with reclosing tests (including no-voltage detection). Can simulate permanent, transitional, and transient faults.
Harmonic test menu. Each analog channel can add DC and harmonics from 1st to 20th order.
Waveform playback menu. Can replay fault recording data in COMTRADE format.
DC voltage and current menu. Tests voltage, current, time, intermediate relays, and three-phase unbalanced relays. Measures action value, return value, and sensitive angle.
