What Nortroll does

Nortroll AS, founded in 1977 in Levanger, Norway, develops and manufactures fault detection and remote control equipment for Medium Voltage (MV) electricity distribution networks. The company's product portfolio is organized into three sub-brands: LineTroll (conductor- and pole-mounted fault passage indicators for overhead lines at 6-132kV), CableTroll (fault current indicators installed on Ring Main Units in underground cable networks at 6-36kV), and ComTroll (a modular Remote Terminal Unit / SCADA system with actuators, repeaters, and short-range radio collectors). Hardware is designed for operation in extreme climates (specified for -40°C to +80°C on the RTU-600), with long-life lithium batteries (10-15 years) and support for multiple communication media (GSM/GPRS, radio, fiber, Ethernet, Rakel/TETRA, LON, Modbus), enabling integration with third-party SCADA platforms or standalone operation.

The company serves electrical utilities and Distribution Network Operators (DNOs) globally, with the value proposition centered on reducing outage time, penalties for non-supplied energy, equipment wear, and line-patrolling risk by enabling rapid fault location, isolation, and re-energization. Go-to-market is sales-led, combining direct sales from the Norwegian headquarters with a distributor network covering 40+ countries and regional offices in Sweden, Malaysia, and the UAE. Revenue is generated through hardware product sales and associated professional services (project management, installation, commissioning, training, and after-sales support). Pricing is not publicly disclosed and is structured per project or per unit depending on configuration. Nortroll operates as a wholly-owned subsidiary of the SICAME Group, an international electrical equipment conglomerate, and is certified to ISO 9001, 14001, 45001, and 27001. No public revenue, funding history, or headcount figures beyond a 1-10 employee range are disclosed.

Core offering

Nortroll develops and manufactures fault detection and remote control equipment for Medium Voltage (MV) electricity distribution networks. The portfolio includes overhead line and underground cable fault passage indicators, Remote Terminal Units (RTUs), motorized switch actuators, and SCADA systems that enable utilities to quickly locate faults, isolate affected sections, and remotely restore power. Products are sold through direct sales and a global distributor network in over 40 countries.

Product overview

Nortroll offers a comprehensive portfolio of power distribution products organized into three main product lines: LineTroll (overhead line fault passage indicators), CableTroll (underground cable fault current indicators), and ComTroll (modular Remote Terminal Units and SCADA systems). The company provides a platform-plus-modules architecture where products can function independently or be integrated into a complete smart grid solution. LineTroll indicators mount on overhead power lines (6-132kV) to detect short circuits and earth faults. CableTroll units are installed on Ring Main Units in substations for underground MV networks (6-36kV). ComTroll RTUs and SCADA systems provide monitoring, control and automation capabilities with various communication protocols. All products are designed for extreme weather conditions and can be mounted on live networks. The system enables utilities to identify fault locations, isolate faulty sections, and restore healthy parts of the network rapidly.
