NEW: current transformer by DOSSENA

The DER3B, differential relay with separate toroid our is a protective device that determines, by using actuators such as coils shunt or undervoltage release, the interruption of the power line if it detects a leakage current to ground type AC, AC pulsating or continuous higher than set threshold. They can be used on LV networks up to 1000V DC (with a pole to ground),...

In systems with isolated neutral IT-M is not required the intervention of the protections for the first fault to earth: the breakdown must be indicated acoustically and optically by one or more small remote panels signaling PSR3. The surveyor is able to detect insulation defects of the resistive type even in presence of continuous voltages. Standards : The safety of...

The PFR RFX is capable of measuring: Power factor (PF), Voltage (TRMS), Current (TRMS), Active power, Reactive power, Temperature (through internal sensor NTC or external probe). It is capable of calculating: Weekly average value of PF (sliding window), Max voltage value, Capacitors overcurrent % and others, upon customer''s requirements. The adjustment of PF is carr...
