Partial Discharge Detector Price: What Drives the Cost

There is no single list price for a partial discharge detector. Two quotations for what looks like "the same" instrument can differ by two or three times, because the price follows the configuration. This page explains what moves the number, so you can read a quotation properly and specify what you actually need.

What determines the price

Factor Why it moves the price
Detection methods A two-method handheld (TEV + AA) sits at the entry level. Each additional method - AE, UHF, HFCT - adds sensors, channels and firmware, so multi-method instruments cost more.
Channels and synchronisation Single-channel units are for survey rounds. Multi-channel units that record several points at once, or synchronise with a phase reference, are used for diagnosis work.
Calibration and certification A traceable calibration certificate and a calibrator are separate items. If your procedure or client requires documented calibration, budget for it.
Accessories and sensors Probes, couplers, clamps and spare sensors are usually quoted separately. A "cheap" detector with three extra sensors often costs more than a multi-method unit.
Software and data handling Wireless apps, reporting software and trending tools vary between models and can be licensed per user or per site.
Branding and packaging OEM branding, neutral packaging and custom labels are quoted as a one-off tooling cost plus a per-unit difference.
Quantity and incoterms Wholesale quantities reduce unit price. The trade term (EXW, FOB, CIF, DDP) and the destination change the landed cost, not the instrument price.

How to compare two PD detector quotations

  1. Same method list. Check both instruments cover the methods you need, not just the headline one.
  2. Same scope of supply. Count sensors, probes, calibrator, case, charger and software licences.
  3. Same calibration. A certificate and a calibrator are the difference between a survey tool and a documented test result.
  4. Same trade term. Compare EXW with EXW, or FOB with FOB, then add freight and duty separately.
  5. Same support. Ask about warranty length, spare parts availability and lead time in writing.

What to put in a request for quotation

  • The assets you inspect (switchgear, cables, GIS, transformers, machines) and their voltage class.
  • Whether you work energised, and which access points you have (enclosure wall, cable earth, GIS compartment, tank surface).
  • Whether you need a handheld survey instrument, online monitoring, or both.
  • Quantity, branding requirement and destination port or address.

With those five lines we can quote a configuration that fits the work, instead of quoting the most expensive instrument in the catalogue.

Where the money is usually saved

  • Right method count. Teams that only survey switchgear rarely use UHF. Not paying for methods you never use is the single biggest saving.
  • Buy from the maker's channel. Working directly with the supplier removes a distribution margin, and buying the detector together with acoustic or thermal instruments removes a second shipment and a second set of freight charges.
  • Standard packaging. Neutral packaging costs less than custom OEM tooling unless you order in volume.

Partial discharge detector price FAQ

How much does a partial discharge detector cost?

It depends on the configuration: how many detection methods the instrument covers, channels, calibration, accessories, software and branding. Send us the assets you inspect and the methods you need and we will quote a specific configuration with its current price.

Why are two PD detector quotations so different?

Usually because they cover different method lists, scopes of supply and calibration. Compare the method list, the included sensors and probes, the calibration certificate and the trade term before comparing the number at the bottom.

Is a multi-method detector cheaper than buying several single-method ones?

For survey work at sites that mix switchgear, cables and machines it usually is, because one instrument covers the common access points. Single-method instruments still make sense where a procedure names one specific method.

Can I get a price for OEM branding and wholesale quantities?

Yes. Send the quantity, the branding requirement and the destination, and we will quote the tooling and per-unit difference together with the instrument price.
