Power Quality Analyzers & Solutions

Approx. Rs 25,000 / Per DayGet Latest Price

Pre-requisites (What we should know before quoting for service)

1. SLD of the plant proposed to be audited
2. Is harmonics study required?
3. Visit by our Engineer helps in understanding exact scope of work.

Typical cost parameters

Cost per day: Rs. 25000 plus GST. If we can make preliminary visit to understand scope of work, we can provide most efficient estimate. HSN/SAC Code: 998331. GST: 18%

Deliverables:

1. Detailed report of analysis of Flicker, Transients frequency & voltage variations (sag & swell)
2. Transient behaviour of mapped points is identified.
3. Exact areas of power loss are identified.
4. If harmonics study is included in the scope of work, harmonics analysis of target non-linear loads is provided.
5. Value added services: Comparison of energy consumption of specified metering points, Development of preventive & predictive maintenance schedules, Assess sensitivity of specific equipment to disturbances.

Typical Service Delivery Timescale

The duration of each audit depends on number of power points identified for the audit. We simplify costs as number of points rises. Certain studies requires us to put our analysis setup running overnight.
