For three phase applications such as manufacturing plants, data centers, medical facilities and commercial buildings, voltage fluctuations are not just an inconvenience, but an operational deterrent that can cripple productivity. Loss of control logic, electrical component failure, or motor malfunction can all be traced to input voltage irregularities. The WTA 3 Phase Regulator overcomes these problems with a combination of precise engineering and localized intelligence. But, any quality hardware needs quality support and technical expertise to provide a sustainable solution. Our support system offers continuous stable, efficient, and trouble-free operation as described below:
PrePurchase Technical Consultation for Proper Sizing
Most of the installation problems of voltage regulators arise from wrong regulator selection. If the chosen regulator is undersized for its load; it will trip when there are peaks of demand, increasing expenses with a non performing system and power loss. Many customers face the difficult task of predicting variable load demands or of dealing with harmonic distortions, both very common issues in a modern building.
WTA technicians start with your pre purchase phase. Application engineers work closely with the client, analyze their system's specific electrical requirements (load type-motor, lighting, data IT; fluctuations range, fault current capacity and ambient environment). Using live readings from their current setup or an onsite measurement, we calculate and recommend the correct WTA 3 Phase Regulator (SCR, relay based or servo motor driven) as well as provide single line diagrams and installation notes to electrical contractor. The aim is to eliminate possible errors in regulator sizing while minimizing the overall installation costs.
FactoryTrained Installation and Commissioning Assistance
A voltage regulator that has been poorly wired or improperly setup simply won't work to specification, regardless of the regulator quality. Incorrect connection to the three phase system or an incorrect setting on the bypassed units are two common causes for post installation problems.
WTA can perform either a remote assistance or a site service of installation and commissioning. A WTA technician will support the local electrical team in setting up and configuring the regulator and system on site by verifying correct three phase connection and testing the protection relays and fine adjusting voltage. Field service engineers can also be provided for large-scale installations or sensitive critical environments. The unit is also supplied with connection diagrams and commissioning check lists for easy installation.
24/7 Technical Hotline and Remote Diagnostics
The voltage fluctuations are most likely to occur in off hours, affecting operations and resulting in lost production hours, damaged components, or raw material spoilage. During these hours the waiting time for support must be minimal.
WTA technical staff is available to respond to your calls round the clock, 365 days of the year. All our hotline technicians are knowledgeable with the hardware and software of all our products and will be able to diagnose your problem immediately, helping you step-by-step through menus, or aiding in the interpretation of alarm codes and logged events. Remote diagnostics can be used on some regulators via the unit's communication port (Modbus, RS485 or Ethernet). Through remote access we are able to see what the regulators are measuring (input and output voltage, position of tap and all other alerts) without needing a technician on-site. This usually allows us to solve most issues in minutes, not hours or days.
Spare Parts, Repair Services, and Extended Warranty
Like all electrical equipment, voltage regulators contain components that may eventually require maintenance — thyristors, cooling fans, or contactors. Shipping critical equipment for repair off site or waiting for the necessary spare parts can seriously impact your operation.
WTA stocks all spare parts for every current and discontinued WTA 3 Phase Regulator models. The majority of these can be shipped with 24 hour express delivery service. We have two service centers available for repaired equipment that is under an extended warranty plan, where technicians perform repairs and ship the component back to the client, all in a documented amount of time and at competitive costs. Extended warranty clients may also take advantage of annual site visits where a WTA technician can check over the connections of the system and test its performance. This may increase your regulator's life span for over 15 years, without any malfunction.
Summary
The quality of support and assistance of the WTA 3 Phase Regulator is structured in four key points: pre-installation technical consultation for proper system design and sizing; installation and commissioning assistance from factory trained technicians for a flawless setup; 24/7 support line combined with remote diagnostics capability for instant problem solving; a robust network of spare parts, repair services and an optional extended warranty program. As an official partner and designer of the national industry standards, an OEM with a 50,000 m² production facility, and in-house core component production and integrated intellectual property, WTA not only delivers a high quality 3 phase voltage regulator, but the necessary technical support and services to keep it operating efficiently for many years.
