Description
Features:
Measurement of short circuit loop parameters
- Measurement of short circuit loop impedance in networks with
- rated voltage: 220/380 V, 230 V/400 V, 240/415 V and frequency 45…65 Hz, operating voltage range: 180…460 V
- Indication of short circuit loop resistance R and short circuit loop reactance X
- Measurements of short circuit loop impedance with 15 mA current, without tripping the RCD circuit breaker
- Maximum test current: 7.6 A (at 230 V), 13.3 A (at 400 V)
Testing RCD breakers of AC, A types
- Testing of prompt, short-delay and selective RCDs with rated current values 10, 15, 30, 100, 300, 500 mA
- Measurement of IA trip current and tripping time tA for currents 0.5 IΔn, 1 IΔn, 2 IΔn, 5 IΔn
- RE and UB measurement without RCD tripping
- Extended AUTO function of RCD measurement, with the possibility of measuring ZL-PE with low current
