Overview: The K68 Series Relay Test Set is a three-phase relay test set designed for both automatic and manual testing. It supports various tests including DC, AC, distance, harmonic, and frequency protection ramp tests. Optional PC control software is available for advanced testing capabilities such as differential, advanced distance, and state sequence tests.
Technical Specifications:
- AC Voltage Outputs: The test set provides 4-phase AC outputs with a range of 0 to 300V (L-N) and 2-phase AC outputs with a range of 0 to 600V (L-L). The accuracy is ±2mV for 0.2V-2V and ±0.1% for 2V-300V.
- AC Current Outputs: It offers 3-phase AC outputs with a range of 0 to 35A (L-N) and a single-phase output up to 105A. The accuracy is ±1mA for 0.2A-1A and ±0.1% for 1A-35A.
- Frequency Range: The frequency range is from 1 to 1000Hz with a phase range of -360° to 360° and an accuracy of less than 0.2°.
- DC Outputs: The voltage range is 0 to 300V with an accuracy of ±25mV for 0.5V-5V and ±0.5% for 5V-300V. The current range is 0 to 20A with an accuracy of ±5mA for 0.2A-1A and ±0.5% for 1A-20A.
- Auxiliary DC Voltage Source: Provides a range of 0 to 300V at 0.6A.
- Binary Inputs and Outputs: The device includes 8 pairs of binary inputs and 4 pairs of binary outputs.
- Harmonic Stacking: Capable of stacking harmonics 2 to 9 times.
Ordering Information: The K68 Series is available in different models, with model numbers 05 and 06, offering variations in current and voltage outputs.
