Solutions for residual current monitoring, insulation monitoring, insulation fault location and for the detection of electrical and physical quantities in earthed as well as unearthed systems.
The devices detect and report at an early stage when critical limit values of electrical quantities, such as current, voltage, power, insulation resistance, etc., are exceeded. Hazards for man and machine can thus be reliably avoided. Furthermore, the availability of your machines and systems is increased and production downtimes are minimized. The portfolio ranges from standard devices for monitoring individual measured variables (residual current monitors, insulation monitors, etc.) to multifunctional devices and flexible fault indication systems.
Monitoring Devices Products
Residual current monitors
Insulation monitors
Insulation monitors, also called IMD (Insulation Monitoring Device), monitor the insulation resistance in unearthed AC, AC/DC and DC power supplies (IT systems). This involves measuring the insulation resistance of the IT system to be monitored against earth.
Equipment for insulation fault location
Insulation fault locators enable fast and precise fault location of insulation faults in unearthed power supplies (IT systems) during operation. The insulation fault location system of the VARIMETER EDS series, consisting of a test current generator and an insulation fault locator,
Measuring relays / Monitoring relays
Alongside a multitude of monofunctional safety switching devices, DOLD also offer high-performance multifunctional safety switching devices and systems.
Fault annunciators
The Wireless Safety System from DOLD in the SAFEMASTER W family allows the safe operation and shut-down of systems with hazardous areas, such as in automatic operation.
