安徽PROFITEST S1德国GMC-I安全规格测试仪PROFITEST S1

TT and TN systems with overcurrent protection and RCDs can be simulated with this model (systems with overcurrent protection may be equipped with standard RCCBs as well as with selective RCCBs).

In combination with appropriate measuring and test instruments, all measurements and tests can thus be performed which are required for safety testing of electrical systems with up to 500 V including various types of networks and safety devices.

Measurements include:

Insulation resistance measurements

Low-resistance measurements at equipotential bonding conductors

Measurements for testing RCDs

Loop impedance measurements

Earthing resistance measurements

Line voltage measurements
