Electrical Safety for Personnel, Equipment, and Fire Protection in Industrial Facilities

Service and Main System Protection

Bender products provide advanced ground-fault protection and power isolation transformer solutions for solidly grounded, high-resistance grounded, and ungrounded systems at the service entrance or main. By incorporating Insulation Monitoring devices and Low resistance Grounding, Bender products provide comprehensive protection for service and main system installations. Using the latest monitoring technology, Bender ground-fault monitors provide accurate readings of AC and DC ground faults, including mixed AC/DC ground faults from power conversion equipment.

Bender ground-fault relays, used for system protection, comply with numerous NEC Articles and CEC Rules. Many types of loads that are temporarily disconnected (standby mode) must function as intended at all times. This applies to fire pumps, slide-valve drives, lift motors, or emergency power generators. However, due to humidity or other impacts, ground faults may occur during prolonged downtimes at the supply line or the load itself. If these ground faults are not detected when connecting the installation, the protective device triggers, and operation is impossible. In more severe cases, engine fires may occur. Bender offers solutions, including power isolation transformers to prevent this, as they monitor the insulation resistance of de-energized loads to report faults early.

Branch Ground-Fault Protection and Location

Nowadays, technical installations in all industries are characterized by ever-increasing complexity and automation. From highly developed production lines to robot technology, the amount of equipment that requires a reliable power supply to function smoothly is steadily growing. Therefore, the foundations for reliability and availability of an installation are already laid by selecting the right power supply system.

Bender manufactures ground-fault location equipment for industrial electrical systems of virtually all types and sizes. With this, we can locate ground faults down to the circuit or load level while the system remains online. Automated ground-fault location helps to identify issues before they escalate to the point of requiring a ground fault breaker intervention, thus reducing system downtime and service costs significantly. Fault location systems can be integrated into existing Fieldbus networks and are compatible with Bender's POWERSCOUT cloud-based analytics solution.

Protect personnel and equipment and keep everything online in even the most demanding industrial facilities. Bender products are developed and manufactured with you in mind.

Building Management Integration and Cloud-Based Analytics

Today's smart manufacturing facilities use a building management system to automate processes, trend behaviors, and plan for the future. Bender products are easily integrated into existing fieldbus networks, including Modbus and Profibus. Communication gateways provide web-based interfaces for seeing systems at a glance. POWERSCOUT delivers a comprehensive, scalable cloud-based solution that can span multiple systems, facilities, and locations for facilities looking to redefine how they trend and analyze system health.
