HEYI Current Transducer and its partners provide power monitoring components for Tenaga Nasional Berhad (TNB)’s distribution network in Malaysia. We have extensive experience in substation monitoring in Malaysia, collaborating with companies such as TMS, Toshiba, and EPE. These components allow grid operators to access distribution system data for grid monitoring.

1. Who are HEYI’s equipment supply partners in Malaysia?

1.1 TMS Integration with Local Teams

The TMS distribution network in Malaysia includes several companies specializing in electricity metering and distribution. When upgrading distribution systems, local system integrators verify that existing substation monitoring systems can receive signals from the new system.

1.2 Toshiba Protection and Control System

Toshiba Power Transmission & Distribution Systems Asia provides power distribution systems, as well as protection, control, and automation solutions. When designing electrical switchgear and monitoring systems, various teams must align the electrical measurement data provided by the switchgear with the signals expected from the receiving equipment. This interface determines whether the measurement data can be correctly displayed at the facility.

1.3 Application of EPE switchgear and TNB power distribution system

Malaysian electrical switchgear manufacturer EPE Switchgear has won an order from TNB for a power distribution system. In electrical switchgear development projects, defining checkpoints during the design phase allows the commissioning team to obtain a precise list of measurements that must be verified before acceptance.

2. How does data from the control panel get to the control center?

2.1 Signals from SCADA power distribution and monitoring panels

Electric power distribution systems may require current or voltage to be transmitted from power lines to local displays or remote monitoring systems. To integrate SCADA into substations, a metering interface converts these values into signals that can be interpreted by receiving devices. Multinational corporations use remote terminal units and SCADA systems to monitor devices in their power distribution networks.

2.2 Monitoring channels and protection relays

The protection control panel can use a dedicated measurement channel to transmit measured values to the substation monitoring system for periodic testing. Protection relays detect faults and initiate control actions according to their configuration.

2.3 Checking during debugging

During the facility commissioning process, the team can verify the monitoring system’s readings by comparing known test inputs with the values displayed on the operator screen. If the operator unit and the receiving device use different scales, the signal may have reached the control center, but the original value displayed on the screen may be incorrect.

3. What should a buyer include in the tender documentation for the provision of surveillance services?

3.1 Construction and reconstruction of distribution boxes

Do you require electrical monitoring components in your control cabinet? If so, please provide the measurement points, input signal requirements for receiving equipment, and control cabinet configuration. For modernization projects, we will require your existing circuit diagrams. We will be happy to analyze your substation monitoring needs and provide you with sample solutions or commercial proposals.
