This tester adopts a heavy-duty integrated mobile trolley design, which is convenient for moving in substation sites and has a built-in storage compartment for test lines and accessories. It supports 3-phase current/voltage simultaneous output with a maximum output current of 100A, meeting the testing needs of high-voltage substation protection devices. It meets IEC 61000-4-2 ESD level 4 and IEC 61000-4-4 EFT level 4 anti-interference standards, and has national explosion-proof certification, making it suitable for high-risk substation sites. The tablet-based remote control function allows technicians to operate the tester away from high-voltage areas, improving operation safety.
Overall dimensions with trolley: 1200mm × 700mm × 1500mm; Net weight: 85kg; Power supply options: AC 220V 50/60Hz or built-in 20000mAh lithium-ion battery; 3-phase AC/DC output voltage range: 0~400V; 3-phase AC/DC output current range: 0~100A; Measurement accuracy: ±0.08% of full scale; Anti-interference level: IEC 61000-4-2 ESD level 4, IEC 61000-4-4 EFT level 4; Explosion-proof certification: Ex ib IIB T4 Gb; Continuous operating time: 12 hours with full battery; Communication interfaces: Ethernet, USB, Bluetooth; Data storage capacity: 128GB; Operating temperature range: -10℃ ~ 50℃; Relative humidity: 5%~95% non-condensing.
This tester is applicable to on-site calibration and maintenance of relay protection devices in 220kV~1000kV UHV substations, offshore platform power systems and industrial high-voltage power distribution systems. Typical application scenarios include annual calibration of substation main protection devices, post-maintenance performance verification, emergency fault handling and new substation equipment acceptance testing. It is especially suitable for high-risk, high-electromagnetic-interference substation sites.
