Case Study For Radio Televisyen Malaysia (Rtm) & Pt Indosat Tbk

 

Radio Televisyen Malaysia (RTM)
Radio Televisyen Malaysia, also known as the Department of Broadcasting, Malaysia is the national public broadcaster of Malaysia. Established on 1 April 1946 as Radio Malaya, it is the first and the oldest broadcaster in the country.

 

PT Indosat Tbk
PT Indosat Tbk, doing business as Indosat Ooredoo since 2015 due to Ooredoo’s majority stake, is a telecommunications provider in Indonesia.

 

 

The Problem:
Broadcast Interrupted

 

Broadcasting businesses commonly face issues with voltage drop problems due to long distances and long cable runs – especially in rural outskirts and mountainous areas (as far as 10km from substations). This voltage drop issue affects performance and operational efficiency for broadcasting & communications equipment in Broadcast Relay Stations. Some other loads that are also negatively impacted include airconditioning in remote sites etc.

 

 

The Ashley Edison (UK) Solution 

  • AE offered a reliable voltage drop solution to overcome severe voltage drops plaguing the broadcasting industry.
  • To ensure all broadcasting equipment and sensitive electronics receive optimal, stable, and constant incoming voltages for maximum operational efficiency, we supplied an entire suite of Automatic Voltage Stabilizers (Servo Electronic design), AC Power Line Conditioners, and Isolation Transformers as their solution. Providing optimized voltage drop compensation while maintaining constant voltage regulation at nominal voltage values.
  • Voltage regulation stabilizes the boosted voltage values with high accuracy voltage at ±0.5%, overcoming all irregularities – from no load to full load.
  • Selected units we supplied were built to cater to up to 60% input voltage drops.
  • Depending on the installation sites, a range of both indoor (IP20 enclosures) and outdoor (IP54 enclosures) units were supplied to help these Government broadcasting corporations.
  • Forced-air cooling was customized for enhanced cooling and better efficiency in hot climate environments.
  • Independent Phase Balancing & Control – automatic voltage sensing & precise regulation to ensure the individual phase voltages remain stable regardless of load change or unbalance.
  • Improved Corrosion-Resistant and Salt-Tolerant Design to ensure high maintainability and reliability.
  • Our AVR includes Transient Voltage Surge Protection (TVSS) to protect loads against harmful high energy surges, transients and spikes.
  • Our AVR includes Lightning Surge Protection to protect loads against extremely high voltage surges and transients caused by lightning strikes on the supply line.
  • Remote Operational Status Monitoring for full control over any alerts/information in building management systems
  • High power rating capacity that helped cater for expansions for many many years (need to check how many years), and optimally prolonging AVRs life span so that it minimises risk of overloading and preventing any possible faults – protecting their uptime and revenue.

 

 

The Results

  • No matter how severe the voltage drops were, our clients have managed to solve this problem with Ashley Edison’s voltage compensating solutions.
  • Loads were continuously receiving optimal and stabilized voltage levels at ±0.5% accuracy.
  • Since the installation of our solution, our client’s high-value broadcasting equipment have running on maximum operational efficiency, with no breakdowns, and lesser maintenance was ever required.
  • Over the course of close to 20years, Ashley Edison has supplied over 428 units voltage regulating equipment to the multiple remote site locations throught the world.

Stay Safe With Greater Protection

As safety is our utmost priority, Ashley Edison prepares for every scenario possible
—taking the puzzle out of your protection.

Designed And Engineered With Safety In Mind

We leave nothing to chance when it comes to larger capacity units (≥400KVA). By installing high-quality protective acrylic shields in front of live parts, we ensure the safety of your personnel at all times. For enhanced protection during installation, all distances between uninsulated metal parts, busbars, and cable sizes are compliant with IEC61439-1 and IEC 61439-2 guidelines.

Outfitted with fireproof cable trunking, this protective solution safeguards against long fire exposure even in hazardous areas and explosive atmospheres—providing maximum safety for mission critical applications.

Fuss-Free Installation. Seamless Operations.

To ensure ease of installation, Ashley Edison addresses the concerns of contractors and installers by keeping it simple.

Internal-AVR

ALL TERMINATION POINTS ARE MANUFACTURED FOR EASY ACCESS

We keep the installation process simple and streamlined by allowing sufficient working space for installers. Taking the nut and bolt intrusions into consideration, we ensure that the distance between the uninsulated metal parts, the busbars, and cable sizes are compliant with IEC61439-1 and IEC 61439-2 guidelines.

 

Even in units with larger capacities, all busbar terminals are clearly marked out, and well positioned in line for easy identification of individual input and output terminations. Installation of these terminations are similar to those practised in high voltage transformers.

Universal Presettable Function

The Universal Presettable Function onboard the Ashley Edison MBB Card allows seamless control of your desired output voltage value on all 3 Phases—with just a touch of a button. This multifunctional feature enables each AVR to fully operate with just 1 card, instead of separate cards for each individual phase. Fitted LED Output Voltmeter Display and Alert Indicator better facilitates easy status monitoring while performing maintenance on your AVR.

AE MBB Card

Microcontroller Unit (MCU)

MicroController Unit (MCU) helps you to deliver high speed and reliable efficiency in the AVR’s operations with less heat generation and reduced power consumption. Used in Supercomputers, Surface Mount Technology (SMT) allows components in the Ashley Edison MBB Card to be aligned closer together, creating a more compact and lightweight end product.
