Monitors

DOLD monitoring devices provide reliable supervision of the condition of electrical installations in single-phase, three-phase, DC and hybrid AC-DC systems, even in environments with increased requirements, such as medical applications compliant with the VDE 0107 standard. They offer comprehensive solutions for fault detection, network parameter measurements and continuous insulation condition monitoring.

The offer includes, among others:

Fault annunciator systems – fault signalling systems for quick identification and location of faults in complex systems,
Measuring relays – for precise monitoring of voltage, current, frequency and power factor in industrial and building networks,
Insulation monitoring devices – ensuring continuous monitoring of insulation resistance in IT systems, allowing dangerous drops to be detected before a short circuit occurs,
Insulation fault locators – enable quick identification of the branch of the installation where the problem has occurred, reducing service response times,
Residual current monitors – dedicated to earthed networks (TN, TT), detecting current leaks and protecting against the risk of electric shock.

DOLD products in this group are characterised by high sensitivity, integration with energy management systems and compliance with industry standards. They can be used in industrial facilities, public buildings and the healthcare sector.
