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 I_A trip current and tripping time t_A for currents 0.5 I_Δn, 1 I_Δn, 2 I_Δn, 5 I_Δn
• R_E and U_B measurement without RCD tripping
• Extended AUTO function of RCD measurement, with the possibility of measuring Z_L-PE with low current
• Measurement of I_A and t_A during one RCD tripping

Insulation resistance measurement
