With the modernization of the Philippine national power grid and the continued growth in demand for renewable energy grid integration, the demand for high-precision, long-life, and safety-certified current transformers (CTs) is rapidly increasing. Major Philippine power entities, such as MERALCO, NGCP, and power cooperatives (ECs), are upgrading their metering and protection systems; therefore, stable and accurate current sensing capabilities have become crucial for winning government and power authority tenders.
HEYI RECT series current transformers are designed for power industry applications, and are especially suitable for projects such as power distribution networks, metering upgrades, substation upgrades, pole-mounted transformer monitoring, and renewable energy grid connection in the Philippines.
1.The modernization of the national power grid is accelerating.
NGCP and local power cooperatives are replacing aging equipment to reduce line losses and improve power supply stability. High-precision CT is a core component of the following equipment:
Relay protection
Electricity metering
Feeder monitoring
Transformer protection
2.The demand for grid connection of renewable energy is rising rapidly.
With the increasing number of solar, power plant, rooftop photovoltaic, and wind power projects in the Philippines, precise CT scans are needed to meet grid connection standards and safety requirements.
3.Government-led electrification and rural power supply projects
The Philippines, with its numerous islands and coastline, demands high weather resistance from outdoor equipment. The RECT series performs exceptionally well in the following environments:
high temperature
High humidity
Salt spray (coastal areas)
Outdoor pole and tower environment
Power industry-grade high precision
The RECT series Outdoor current monitoring CT possesses long-term, stable, and high-precision measurement capabilities, and is suitable for:
Electricity Bureau Revenue Measurement
Substation monitoring
Feeder protection device
Higher accuracy means lower error and better compliance with the stringent metering standards of Philippine power projects.
Compact design, quick installation, suitable for on-site construction
The RECT series features a compact design and is easy to install.
Some models support tool-free quick snap-fit.
Compact size, suitable for narrow switchboard spaces
Supports multiple cable specifications
Reduce construction time and improve the competitiveness of bidding proposals.
High-strength design resistant to the Philippine climate
Facing the typical harsh environment of the Philippines (high temperature, high humidity, salt spray, UV radiation), the RECT series adopts:
RECT series conforms to:
IEC,CE&RoHS
And can be used for:
Main applications of HEYI RECT series in the Philippines
Intelligent metering system (AMI / Energy Monitoring)
Suitable for power bureau metering upgrades, energy consumption monitoring, and load management systems.
Solar/Wind Power Projects
It provides accurate and stable current detection for inverter monitoring and grid connection protection.
Distribution transformer protection
Applicable to common uses in the Philippines:
With the development of the Philippine EV market, reliable CTs are needed for charging load monitoring and protection.
How can RECT help you win more projects in the Philippines
