Why is this metering current transformer increasingly favored in Middle Eastern power projects

HEYI Electric’s CP series Metering current transformer series is both “beautifully compliant” and “safe to use”, and can also be customized according to project requirements .

In the hot and dusty working environments of Saudi Arabia, the UAE, and Qatar in the Middle East , many customers are most concerned about difficulties encountered in audits , installation mismatches , and unstable current transformer accuracy. The HEYI CP metering current transformer gradually addresses these three challenges .

compliance certification : compliance with test standards and test reports

It is fully consistent with the “standard language ” required by power authorities such as DEWA and SEC , and the technical terms correspond one-to-one .

Third-party type test report in hand:

It is not just a verbal statement of “compliance”, but contains a conclusion page, a report number, and reviewable data.

Routine testing before leaving the factory:

each one has a “certificate of conformity” and is directly used as “hard currency” in the bidding documents.

The result is:

just tick the technical deviation form and it will pass, the review will not be tangled, and procurement will be easier.

 Only those who truly adapt to the environment can be shortlisted :

HEYI’s CP current transformers are designed for the heat and dust of the Middle East

Not afraid of high temperatures :

Temperature rise tests are conducted according to the actual installation scenario, and issues that need to be addressed , such as heat dissipation in the switch cabinet and the direction of the conductor busbar, are taken into consideration.

Dust-proof :

The housing and wiring terminals are designed strictly in accordance with specifications, and the control/auxiliary circuits provide solutions with a rating of no less than IP20, making the complete set of equipment safer to use .

The nameplate is clearly printed :

primary/secondary rating, Ith (short-time thermal stability current), Idyn (dynamic stability current), polarity and terminals are all fully marked-during construction and installation , the short-circuit capacity is checked and errors in construction wiring are avoided as much as possible .

Suitable for both metering and protection scenarios: HEYI CP current transformers meet dual standards

accurate metering : Supports accuracy levels of 0.2S/0.5S/1.0, meeting the standards for electricity metering and energy efficiency auditing .

More stable protection :

Conventional 5P10/5P20 and other protection requirements are naturally covered, and we can also customize relay protection for leakage scenarios .

VA load matching: 2.5/5/10/15 VA and other points are optional, matching the actual power consumption of your meter/relay.

OEM customization: meet the special requirements of your project

The primary ratio range is wide :

from 100/5A to 1600/5A are all within the design range , and multiple ratio solutions ( 3200A ) are also supported .

The window/busbar size is based on the power project :

there are ready-made solutions for common specifications such as aperture Φ50.5, and special sizes can also support mold customization .

Flexible installation:

inside/outside the cabinet, ring network cabinet, distribution box , etc., adjust the current transformer structure and terminal layout according to your complete equipment structure.

Core Value: Fewer design changes, less rework, and fewer NCRs (non-conformities), resulting in more confident bidding and more stable delivery.

A set of information to meet the requirements of the bidding documents

A “three-piece set” has been specially prepared for bidding, which explains the evaluation focus in one go:

Compliance Certification : Check IEC 61869-1/-2 item by item and clearly tick “Meets”.

Type test report summary: report number, test scope, conclusion page, all clearly visible.

Selection and size table:

primary ratio, secondary, accuracy, VA, window size, terminal diagram, on-site verification to avoid pitfalls.

You only need to provide the project specifications and current level list, and we will immediately generate your exclusive bidding attachments.

Three typical application scenarios

Public Utilities/Distribution Networks:

Focus on both metering and protection, with stable accuracy, complete records, and easy procurement.

Industrial and commercial power distribution/complete cabinet factory:

can be installed even in limited space, terminals and nameplates are friendly, and there is no need for worry about delivery.

New energy and large-scale industrial and mining:

In high temperature and load fluctuation scenarios, protection level and stability are more critical.

Summary:
HEYI’s CP current transformer = IEC 61869 hard-core compliance + true Middle East operating conditions adaptation + feasible OEM customization + one-stop bidding package.

Not only can the review be passed more smoothly , but the application effect on the construction site will also be better .
