Safety and Protection Relays

Captech offers a range of electrical safety equipment including protection relays and fault monitoring devices to protect both people and infrastructure.

Captech are partnered with Bender, a global leader in electrical safety solutions for all industries and applications.

 

When is fault monitoring right for you? Are you experiencing…

  1. Unstable equipment operation including spurious tripping of protection devices
  2. Production losses due to unplanned downtime to service equipment
  3. High maintenance costs

What is a fault monitoring device?

Fault monitoring devices are designed to detect and locate developing earth faults on essential electrical systems and equipment to enable repairs to be carried out prior to system failure.

They can be used in grounded and ungrounded system applications to ensure the integrity of an electrical circuit, improve electrical safety for personnel and reduce the risk of damage to equipment due to earth faults, insulation failure, under/over voltage, under/over current, phase unbalance and frequency deviation conditions.

Our Products

Bender specialises in the design and manufacture of highly sensitive insulation monitoring devices and on-line earth fault location systems and are recognised across a wide range of industries.

Bender has a range of monitoring devices including:

Insulation Monitoring Devices

Bender Insulation Monitoring Devices provide appropriate solutions for a diverse range of electrical power supplies. Accounting for all system structures and loads, Insulation Monitoring Devices using Bender’s patented measuring principles guarantee reliable evaluation of the insulation resistance for a number of applications.

Residual Current Monitoring Devices

Bender residual current monitors for earthed power supply systems (TN/TT systems) monitor electrical installations for residual and/or fault currents. The devices display the latest measured value and signal when pre-set response values are exceeded as required by the relevant standards.

Integrity Monitoring Devices

The occurrence of loose connections between the NER and star point or earth, or the loss of integrity of the NER results in the conversion of the resistance grounded system into an ungrounded system, rendering the current sensing earth fault detection ineffective and a false belief that the system is in a healthy functioning state.

Current and Voltage Monitoring Devices

Bender’s line of voltage and current relays are powerful, fully-featured devices which can monitor over and under voltage, over and under current and over and under frequency. Three-phase voltage monitoring devices also monitor phase sequence and failure. All compact devices feature digital displays showing values in real-time and also allow for entering precise alarm values.

Power Quality and Energy Monitoring Devices

To ensure personnel and equipment safety, operating conditions of electrical installations have to be monitored continuously. PEM series universal measuring devices (Power Quality and Energy Measurement) record all relevant parameters including current, voltage, frequency, power, harmonics and the energy consumption of electrical supply systems.
